1 Oracle Database 11g Release 1 (11.2.0.1) New Features

This chapter contains descriptions of all of the features that are new to Oracle 11g Database, Release 2. This chapter contains the following sections:

- Application Development

- Availability

- Business Intelligence and Data Warehousing

- Clustering

- Database Overall

- Diagnosability

- Performance

- Security

- Server Manageability

- Unstructured Data Management

1.1 Application Development

The following sections describe the new application development features for Oracle Database 11g Release 2 (11.2).

1.1.1 Oracle Application Express

The following sections describe Oracle Application Express features.

1.1.1.1 Application Date Format

You can now define a date format to be used throughout an application. This date format is used to alter the NLS_DATE_FORMAT database session setting prior to showing or submitting any page within the application. This format is used by all reports showing dates and is also picked up by form items of type "Date Picker (use Application Date Format)".

The ability to specify a date format at the application level ensures consistency across the application. Therefore, whenever dates are displayed or input, they are in the same format.

1.1.1.2 Custom Themes

In addition to the default themes provided with Oracle Application Express, you can create your own customized themes. You can either start with one of the twenty standard themes available with Oracle Application Express and modify the underlying templates or define your own templates from scratch. Each theme consists of a set of templates defined with cascading style sheets (CSS) and HTML.

The ability to publish custom themes enables you to design a specific look and feel to meet your corporate requirements and then publish them as a theme for all other applications to use.

1.1.1.3 Declarative BLOB Support

Declarative BLOB support enables files to be declaratively uploaded in forms, and downloaded or displayed using reports. BLOB display and download can also be authored procedurally using PL/SQL.

The storing of binary large objects (BLOBs) within the database is growing in popularity due to the many advantages over storing content on disparate file systems. By incorporating declarative support for managing BLOBs into Application Express, the loading and manipulating of content is greatly simplified.

1.1.1.4 Documented JavaScript Libraries

This release includes an improved framework for advanced Oracle Application Express developers to build and leverage custom Web 2.0 capabilities, improving performance and enabling developers to create more dynamic application widgets. Oracle Application Express also includes the ability to suppress standard JavaScript and CSS files. All included JavaScript files are now compressed to improve page load time.

Many developers want to extend their applications to include additional Web 2.0 capabilities or to minimize the page weight for use on mobile devices such as iphones and smartphones. The documentation and declarative capabilities allow developers to design applications for these disparate requirements.

1.1.1.5 Enhanced Report Printing

Release 3.1 includes XML as a download format and supports multiple SQL statements.

Oracle Application Express interactive reporting provides the ability to manipulate the way in which the data is displayed on the screen. Users can also download this data in various formats including PDF, RTF, XLS and now XML.

1.1.1.6 Forms Conversion

Forms Conversion captures the design of existing Oracle Forms and automatically converts some components, primarily the user interface. Other components, such as complex triggers, need to be manually converted post-generation.

Moving to native HTML is not seamless and changes to the user interface are required to deliver optimal Web interactivity.

The Oracle Application Express Forms Conversion enables you to take advantage of Oracle Application Express dynamic HTML capabilities, including interactive reports. Given the similarities between Oracle Forms and Oracle Application Express development (both use SQL and PL/SQL), retraining requirements are also low.

1.1.1.7 Improved Security

Oracle Application Express offers a number of security enhancements. Key enhancements include the ability to declaratively encrypt session state and specify session time outs for maximum idle time and maximum session duration as well as create new password item types that enable users to enter passwords without ever saving them to session state.

Other features include reducing the privileges required by the Oracle Application Express database account, disabling database monitoring by default, and the ability to specify HTTPS for administration. In addition, administrators can now restrict password reuse. This release also includes a new Hidden and Protected item type. This item type greatly simplifies the developer's task of protecting item session state. This, together with other minor improvements, makes the default security functionality more robust within Oracle Application Express.

The additional declarative security capabilities make it easier for developers and administrators to harden the security of their applications and the development environment. These new capabilities complement existing Oracle Application Express security features some of which include flexible authentication, authorization schemes, and URL tampering protection.

1.1.1.8 Interactive Reporting Region

Interactive Reporting Regions enable end users to customize reports. Users can alter the layout of report data by choosing the columns they are interested in, applying filters, highlighting, and sorting. They can also define breaks, aggregations, different charts, and their own computations. Users can create multiple variations of the report and save them as named reports and download to various file formats including comma-delimited file (CSV) format, Microsoft Excel (XLS) format, Adobe Portable Document Format (PDF), and Microsoft Word Rich Text Format (RTF).

Oracle Application Express Interactive Reporting enables developers to quickly develop reports that can be manipulated by end users to meet a wide range of reporting requirements. Therefore, instead of developers having to define specific report layouts for different users or groups, they can define a common report that can be used to meet the majority of the different requirements.

1.1.1.9 Runtime-Only Installation

For testing and production instances, Oracle Application Express now supports the ability to install a runtime version of Oracle Application Express. This minimizes the installed footprint and privileges. Scripts are also provided to remove or add the developer interface from an existing instance.

The ability to implement a runtime-only environment improves application security as developers cannot inadvertently or maliciously update a production application.

1.1.2 Other General Development Features

The following sections describe new features in the areas of OCI, Pro*C, JDBC, and other development APIs.

1.1.2.1 Support WITH HOLD Option for CURSOR DECLARATION in Pro*C

The WITH HOLD option can now be specified during cursor declaration.

This new option provides easy migration of Pro*C applications.

Pro*C/C++ Programmer's Guide for details

1.1.2.2 Pro*C Support for 8-Byte Native Numeric Host Variable for INSERT and FETCH

Oracle Call Interface (OCI) now provides Pro*C support for 8-byte native numeric host variable for INSERT and FETCH on 32-bit and 64-bit platforms.

Fusion applications need Pro*C to be able to support 8-byte native data type for bind/define while inserting or fetching data to and from a NUMBER(18) column.

See Also:

Pro*C/C++ Programmer's Guide for details

1.1.2.3 Pro*COBOL Support for 8-Byte Native Numeric Host Variable for INSERT and FETCH

Oracle Call Interface (OCI) now provides Pro*COBOL support for 8-byte native numeric host variable for INSERT and FETCH on 32-bit and 64-bit platforms.

Fusion applications need Pro*COBOL to be able to support 8-byte native data type for bind/define while inserting or fetching data to and from a NUMBER(18) column.

1.1.2.4 JDBC Support for Time Zone Patching

The JDBC driver is updated to conform with the new time zone upgrading scheme.

This feature provides a simplified time zone patching process. As a result, Java applications using the TIMESTAMP WITH TIME ZONE data type are immune to Daylight Saving Time (DST) changes.

1.1.2.5 JDBC Support for SecureFile Zero-Copy LOB I/O and LOB Prefetching

JDBC now supports SecureFile zero-copy LOB I/O and LOB prefetching.

This feature allows performant and secure Java access to structured (relational) and unstructured data.

See Also:

Oracle Database JDBC Developer's Guide for details

1.1.2.6 OCI Support for 8-Byte Integer Bind/Define

Oracle Call Interface (OCI) now provides support for 8-byte integer bind/define on 32-bit and 64-bit platforms.

Fusion applications need Pro*C or Pro*COBOL to be able to support 8-byte native data type for bind/define while inserting or fetching data to and from a NUMBER(18) column. Pro*C or Pro*COBOL need this support from OCI to be able to pass it on to application developers.

Oracle Call Interface Programmer's Guide for details

1.2 Availability

The focus of this Availability section is aimed towards providing capabilities that keep the Oracle database available for continuous data access, despite unplanned failures and scheduled maintenance activities. These various capabilities form the basis of Oracle Maximum Availability Architecture (MAA), which is the Oracle blueprint for implementing a highly available infrastructure using integrated Oracle technologies.

1.2.1 Backup and Recovery

The following sections describe new features in this release that provide improvements in the area of backup and recovery.

1.2.1.1 Automatic Block Repair

Automatic block repair allows corrupt blocks on the primary database or physical standby database to be automatically repaired, as soon as they are detected, by transferring good blocks from the other destination. In addition, RECOVER BLOCK is enhanced to restore blocks from a physical standby database. The physical standby database must be in real-time query mode.

This feature reduces time when production data cannot be accessed, due to block corruption, by automatically repairing the corruptions as soon as they are detected in real-time using good blocks from a physical standby database. This reduces block recovery time by using up-to-date good blocks from a real-time, synchronized physical standby database as opposed to disk or tape backups or flashback logs.

1.2.1.2 Backup to Amazon Simple Storage Service (S3) Using OSB Cloud Computing

Oracle now offers backup to Amazon S3, an internet-based storage service, with the Oracle Secure Backup (OSB) Cloud Module. This is part of the Oracle Cloud Computing offering.

This feature provides easy-to-manage, low cost database backup to Web services storage, reducing or eliminating the cost and time to manage an in-house backup infrastructure.

1.2.1.3 DUPLICATE Without Connection to Target Database

DUPLICATE can be performed without connecting to a target database. This requires connecting to a catalog and auxiliary database.

The benefit is improved availability of a DUPLICATE operation by not requiring connection to a target database. This is particularly useful for DUPLICATE to a destination database where connection to the target database may not be available at all times.

See Also:

Oracle Database Backup and Recovery User's Guide for details

1.2.1.4 Enhanced Tablespace Point-In-Time Recovery (TSPITR)

Tablespace point-in-time recovery (TSPITR) is enhanced as follows:

- You now have the ability to recover a dropped tablespace.

- TSPITR can be repeated multiple times for the same tablespace. Previously, once a tablespace had been recovered to an earlier point-in-time, it could not be recovered to another earlier point-in-time.

- DBMS_TTS.TRANSPORT_SET_CHECK is automatically run to ensure that TSPITR is successful.

- AUXNAME is no longer used for recovery set data files.

This feature improves usability with TSPITR.

1.2.1.5 New DUPLICATE Options

The following are new options for the DUPLICATE command:

- NOREDO
NOREDO indicates that archive logs are not applied. Because targetless DUPLICATE does not connect to the target database, it cannot check if the database is running in NOARCHIVELOG mode. It can also be used during regular duplication to force a database currently in ARCHIVELOG mode to be recovered without applying archive logs (for example, because it was in NOARCHIVELOG mode at the point-in-time it is being duplicated).

- UNDO TABLESPACE <tsname> [ , <tsname> ... ]
When not connected to a recovery catalog and not connected to an open target database, RMAN cannot obtain the list of tablespaces with undo segments, therefore, you must specify them with this clause.

This feature improves the usability of the DUPLICATE command.

1.2.1.6 New SET NEWNAME Clauses and Format Options

The following are new clauses and format options for the SET NEWNAME command:

- A single SET NEWNAME command can be applied to all files in a tablespace, or for all files in the database. For example:

SET NEWNAME FOR TABLESPACE <tsname> TO <format>;

Or,

SET NEWNAME FOR DATABASE TO <format>;

- New format identifiers for SET NEWNAME...<format> are as follows:

- %U
Unique identifier. data_D-%d_I-%I_TS-%N_FNO-%f

- %b
UNIX base name of the original data file name. For example, if the original data file name was ORACLE_HOME/data/tbs_01.f, then %b is tbs_01.f.

The benefit is improved flexibility of RESTORE, DUPLICATE, and TSPITR.

See Also:

Oracle Database Backup and Recovery User's Guide for details

1.2.1.7 Tablespace Checks in DUPLICATE

The DUPLICATE...TABLESPACE and DUPLICATE... SKIP TABLESPACE commands now perform the following initial checks:

- Excluded tablespaces are checked to see if they contain any objects owned by SYS.

- DBMS_TTS.TRANSPORT_SET_CHECK is run to ensure that the set of tablespaces being duplicated are self-contained before the actual duplicate process.

These checks are not possible for a targetless DUPLICATE as they are required to be run at the target database.

This feature improves usability of DUPLICATE. Any tablespace issues are immediately identified prior to commencement of the actual duplicate operation.

1.2.2 Online Application Maintenance and Upgrade

The following sections describe online application maintenance and upgrade features.

1.2.2.1 Edition-based Redefinition

Edition-based redefinition allows an application's database objects to be changed without interrupting the application's availability by making the changes in the privacy of a new edition. Every database has at least one edition. The DBA creates a new edition as a child of the existing one. The changes are made in the child edition while you continue to use the parent edition. When needed, changes to data are made safely by writing only to new columns or new tables not seen by the old edition. Editioning views expose a different projection of each changed table into each edition to allow each to see just its own columns. Crossedition triggers propagate data changes made by the old edition into the columns of the new edition. When the installation of the changes is complete, some users start to use the new edition while others drain off the old edition. Here, crossedition triggers propagate data changes made by the new edition into the columns of the old edition.

Large, mission critical applications are often unavailable for long periods of time while database objects are patched or upgraded. Edition-based redefinition allows this cost to be avoided.

Oracle Database Advanced Application Developer's Guide for details

1.2.2.2 Enhance CREATE or REPLACE TYPE to Allow FORCE

The FORCE option can now be used in conjunction with the CREATE or REPLACE TYPE command.

This feature provides enhanced usability and allows a CREATE or REPLACE TYPE operation to be performed even when TYPE dependent objects are present. However, if at least one TABLE dependent is present, then FORCE does not allow CREATE or REPLACE TYPE to succeed.

See Also:

Oracle Database Object-Relational Developer's Guide for details

1.2.2.3 Fine-Grained Dependencies for Triggers

Oracle Database 11g Release 1 (11.1) brought both fine-grained dependency tracking and the new possibility that a trigger might be a dependency parent by virtue of the new FOLLOWS keyword.

In release 11.1, dependents on triggers did not have fine-grained dependency. In release 11.2, this fine-grained dependence exists. (Release 11.2 also provides the new PRECEDES keyword which also allows trigger-upon-trigger dependencies.)

See Also:

Oracle Database Advanced Application Developer's Guide for details

1.2.2.4 IGNORE_ROW_ON_DUPKEY_INDEX Hint for INSERT Statement

With INSERT INTO TARGET...SELECT...FROM SOURCE, a unique key for some to-be-inserted rows may collide with existing rows. The IGNORE_ROW_ON_DUPKEY_INDEX allows the collisions to be silently ignored and the non-colliding rows to be inserted. A PL/SQL program could achieve the same effect by first selecting the source rows and by then inserting them one-by-one into the target in a block that has a null handler for the DUP_VAL_ON_INDEX exception. However, the PL/SQL approach would take effort to program and is much slower than the single SQL statement that this hint allows.

This hint improves performance and ease-of-programming when implementing an online application upgrade script using edition-based redefinition.

Oracle Database SQL Language Reference for details

1.2.3 Oracle Data Guard

The following sections describe new features in this release that provide improvements in Oracle Data Guard.

1.2.3.1 Compressed Table Support in Logical Standby Databases and Oracle LogMiner

Compressed tables (that is, tables with compression that support both OLTP and direct load operations) are supported in logical standby databases and Oracle LogMiner.

With support for this additional storage attribute, logical standby databases can now provide data protection and reporting benefits for a wider range of tables.

See Also:

Oracle Data Guard Concepts and Administration for details

1.2.3.2 Configurable Real-Time Query Apply Lag Limit

A physical standby database can be open for read-only access while redo apply is active only if the Oracle Active Data Guard option is enabled. This capability is known as real-time query.

The new STANDBY_MAX_DATA_DELAY session parameter can be used to specify a session-specific apply lag tolerance, measured in seconds, for queries issued by non-administrative users to a physical standby database that is in real-time query mode.

This capability allows queries to be safely offloaded from the primary database to a physical standby database, because it is possible to detect if the standby database has become unacceptably stale.

See Also:

Oracle Data Guard Concepts and Administration for details

1.2.3.3 Integrated Support for Application Failover in a Data Guard Configuration

Applications connected to a primary database can transparently failover to the new primary database upon an Oracle Data Guard role transition. Integration with Fast Application Notification (FAN) provides fast failover for integrated clients.

Flexibility and manageability of disaster recovery configurations using Oracle Data Guard is improved.

See Also:

Oracle Data Guard Broker for details

1.2.3.4 Support Up to 30 Standby Databases

The number of standby databases that a primary database can support is increased from 9 to 30 in this release.

The capability to create 30 standby databases, combined with the functionality of the Oracle Active Data Guard option, allows the creation of reader farms that can be used to offload large scale read-only workloads from a production database.

Oracle Data Guard Concepts and Administration for details

1.3 Business Intelligence and Data Warehousing

The following sections describe new Business Intelligence and Data Warehousing features for Oracle Database 11g Release 2 (11.2).

1.3.1 Improved Analytics

The following sections describe new and improved analytical capabilities in this release.

1.3.1.1 Analytic Functions 2.0

New and enhanced analytical functions are introduced in this release. A new ordered aggregate, LISTAGG, concatenates the values of the measure column. The new analytic window function NTH_VALUE (a generalization of existing FIRST_VALUE and LAST_VALUE functions) gives users the functionality of retrieving an arbitrary (or nth) record in a window.

The LAG and LEAD functions are enhanced with the IGNORE NULLS option.

The new and enhanced SQL analytical functions allow more complex analysis in the database, using (simpler) SQL specification and providing better performance.

See Also:

Oracle Database Data Warehousing Guide for details

1.3.1.2 Recursive WITH Clause

The SQL WITH clause has been extended to enable formulation of recursive queries.

Recursive WITH clause complies with the American National Standards Institute (ANSI) standard. This makes Oracle ANSI-compatible for recursive queries.

See Also:

Oracle Database SQL Language Reference for details

1.3.2 Improved Data Loading

The following sections describe new and improved data loading capabilities in this release.

1.3.2.1 EXECUTE Privilege for DIRECTORY Objects

EXECUTE privilege is allowed for DIRECTORY objects in this release. The ORACLE_LOADER access driver creates a process that runs a user-specified program. That program must live in a directory path specified by a directory object defined in the database. Only a user that has been given EXECUTE access to the directory object is allowed to run programs in it.

This feature allows the DBA to control who is allowed to run preprocessors as part of loading data with external tables. It also allows the DBA to restrict which programs those users can run. No existing users with access to the directory object are allowed to run any programs from that directory unless the DBA gives them EXECUTE access to that directory.

See Also:

Oracle Database Utilities for details

1.3.2.2 Preprocessing Data for ORACLE_LOADER Access Driver in External Tables

The syntax for the ORACLE_LOADER access driver is extended in this release to allow specification of a program to preprocess the data files that are read for the external table. The access parameters can specify the name of a directory object and the name of an executable file in that directory object. When the access driver needs to read data from a file, it creates a process that runs the specified program, passing in the name of the data file. The output from the program is passed into the access driver which parses the data into records and columns.

The initial use of this feature is by a customer who needs to load data that is stored in compressed files. The user specifies the name of the program used to decompress the file as part of the access parameters. The access driver reads the output of the decompression program.

Large customers want to load data from compressed files which requires less disk space and uses the I/O bandwidth between the disk and memory more efficiently.

Oracle Database Utilities for details

1.3.3 Improved Partitioning

The following sections describe new and improved partitioning capabilities in this release.

1.3.3.1 Allow Virtual Columns in the Primary Key or Foreign Key for Reference Partitioning

Virtual columns can be used as the primary or the foreign key column of a reference partition table.

Allowing the use of virtual columns for reference partitioned tables enables an easier implementation of various business scenarios using Oracle Partitioning.

1.3.3.2 System-Managed Indexes for List Partitioning

System-managed domain indexes are now supported for list partitioned tables.

This feature provides enhanced completeness of domain-specific indexing support for partitioning to meet user requirements including Oracle XML DB. Performance of local domain indexes on list partitioned tables is improved in this release.

See Also:

Oracle Database SQL Language Reference for details

1.3.4 Improved Performance and Scalability

The following sections describe new and improved performance and scalability capabilities in this release.

1.3.4.1 In-Memory Parallel Execution

Traditionally, parallel execution has enabled organizations to manage and access large amounts of data by taking full advantage of the I/O capacity of the system. In-memory parallel execution harnesses the aggregated memory in a system to enhance query performance by minimizing or even completely eliminating the physical I/O needed for a parallel operation. Oracle automatically decides if an object being accessed using parallel execution benefits from being cached in the SGA (buffer cache). The decision to cache an object is based on a well defined set of heuristics including size of the object and the frequency that it is accessed. In an Oracle RAC environment, Oracle maps fragments of the object into each of the buffer caches on the active instances. By creating this mapping, Oracle knows which buffer cache to access to find a specific part or partition of an object to answer a given SQL query.

In-memory parallel query harnesses the aggregated memory in a system for parallel operations, enabling it to scale out with the available memory for data caching as the number of nodes in a cluster increases. This new functionality optimizes large parallel operations by minimizing or even completely eliminating the physical I/O needed because the parallel operation can now be satisfied in memory.

Oracle Database VLDB and Partitioning Guide for details

1.3.4.2 Minimal Effort Parallel Execution - Auto Degree of Parallelism (DOP) and Queuing

When activated, Oracle determines the optimal degree of parallelism (DOP) for any given SQL operation based on the size of the objects, the complexity of a statement, and the existing hardware resources.

The database compensates for wrong or missing user settings for parallel execution, ensuring a more optimal resource consumption and overall system behavior.

See Also:

Oracle Database VLDB and Partitioning Guide for details

1.3.4.3 The DBMS_PARALLEL_EXECUTE Package

The DBMS_PARALLEL_EXECUTE package provides subprograms to allow a specified INSERT, UPDATE, DELETE, MERGE, or anonymous block statement to be applied in parallel chunks. The statement must have two placeholders that define the start and end limit of a chunk. Typically, these are values for the rowid or a surrogate unique key in a large table. But, when an anonymous block is used, the block can interpret the values arbitrarily. The package has subprograms to define ranges that cover the specified table. These include rule-based division of a table's rowid or key range and support user-defined methods. The SQL statement together with the set of chunk ranges define a task. Another subprogram starts the task. Each task is processed using a scheduler job and automatically commits when it completes. Progress is logged. Untried, successful, and failed chunks are flagged as such on task completion or interruption. Another subprogram allows the task to resume to try untried and failed chunks.

Many scenarios require the bulk transformation of a large number of rows. Using an ordinary SQL statement suffers from the all-or-nothing effect. In the common case, where the transformation of one row is independent of that of other rows, it is correct to commit every row that is transformed successfully and to roll back every row where the transformation fails. Some customers have implemented schemes to achieve this from scratch, using the Oracle Scheduler and suitable methods to record progress. This package provides a supported solution and adds database-wide manageability through new catalog views for parallel task metadata. The package is especially useful in online application upgrade scenarios to apply a crossedition trigger to all the rows in the table on which it is defined.

1.3.5 Oracle Warehouse Builder

The following sections describe improvements to the extraction, transformation, and loading (ETL) capabilities available with Oracle Warehouse Builder (OWB).

1.3.5.1 Advanced Find Support in Mapping Editor

The mapping editor has been enhanced with advanced find capabilities to make it easier to locate and make updates to operators, groups, and attributes in a mapping diagram, in the Available Objects tab, and in the Selected Objects tab.

This feature enhances ETL mapping developer productivity, especially on large and complex mappings and, for example, when working with complex data sources with large numbers of tables, views, or columns.

See Also:

Oracle Warehouse Builder Data Modeling, ETL, and Data Quality Guide for details

1.3.5.2 Business Intelligence Tool Integration

Oracle Warehouse Builder (OWB) now offers metadata integration with Oracle Business Intelligence Standard Edition (Discoverer) as well as Oracle Business Intelligence Enterprise Edition.

For Oracle Business Intelligence Enterprise Edition (OBI EE), this feature allows derivation of ready-to-use physical, business model and presentation layer metadata from a data warehouse design, visualization and maintenance of the derived objects from within OWB, and deployment of the derived objects in the form of an RPD file that can be loaded into OBI EE.

Oracle Discoverer integration was added in a previous release, and includes derivation of metadata for Discoverer from the data warehouse design, and deploying those derived objects into Discoverer. In this release, similar capabilities are now available for OBI Enterprise Edition. All business intelligence application objects are modeled in OWB and can be included in lineage and impact analysis at the column level.

Customers using Oracle business intelligence tools with their Oracle data warehouses can get better answers from their warehouses faster, with no additional design or development effort.

1.3.5.3 Copy and Paste of Operators and Attributes in Mapping Editor

In the mapping editor, users can now copy and paste operators within a mapping or across mappings, including attribute settings.

This enhancement saves time and reduces errors in the development of complex ETL mappings that reuse common or similar elements.

1.3.5.5 Enhanced Support for Flat File Imports

There are numerous support improvements for importing flat files, including a simplified Flat File Sampling wizard, support for multi-character and hexadecimal format delimiters and enclosures, simplified support for fixed format fields, and support for bulk flat file loads into heterogeneous targets.

Flat files are frequently used for simple and high performance data movement in ETL applications. These changes improve ETL developer productivity and provide flexible handling of flat files in more scenarios.

1.3.5.6 Enhanced Table Function Support

OWB now has improved support for table functions, including importing metadata for existing table functions, an editor for creating table functions from within OWB, and better support for table functions in mappings.

Improved support simplifies using table functions for much more flexible and powerful transformations, such as user-defined aggregations and data mining sampling operators.

1.3.5.7 Experts Available in Editor Menu

It is now possible to add OWB experts to the mapping editor menu.

This feature makes it possible to enhance and extend the functionality of the mapping editor, improving developer productivity.

1.3.5.8 Expression Editing in Operator Edit Dialog

Expressions associated with operator attributes can now be entered directly into an Operator Edit Dialog or Expression Editor, rather than requiring that these expressions be entered into a property in the Property Inspector.

Developers can finish more of their work in one place when creating operators in ETL mappings, thus improving their productivity.

See Also:

Oracle Warehouse Builder Data Modeling, ETL, and Data Quality Guide for details

1.3.5.9 Grouping and Spotlighting of Objects in Mapping Editor

In the mapping editor, users can now temporarily or permanently group objects in the mapping editor so that they are collapsed to a single icon. This hides complexity in mappings. Users can also spotlight a single operator, which temporarily hides all objects in the mapping except for those objects that connect directly to the operator.

These features improve productivity for developers working with complex mappings with large numbers of operators.

See Also:

Oracle Warehouse Builder Data Modeling, ETL, and Data Quality Guide for details

1.3.5.10 Improved Management of Locations Registered in Multiple Control Centers

1.3.5.12 Key Lookup Operator Enhancements

Extensive changes have been made to the key lookup operator:

- More efficient use of screen real estate.

- Support for non-equality lookups.

- Dynamic lookups, where the lookup table may be modified during the mapping execution.

These changes make the lookup operator more powerful in many situations, including improving Type 2 slowly changing dimension support.

1.3.5.13 Mapping Debugger Enhancements

There are numerous enhancements to the OWB mapping editor, including:

- Improved support for watch points and enabling and disabling individual break points.

- Support for user-defined type columns.

- Enhanced support for numerous existing operators, such as VARRAY, EXPAND, and CONSTRUCT.

- Support for key lookup and table function operators.

- Support for correlated joins.

- Improved cleanup of debugger-specific objects.

These enhancements improve productivity for ETL mapping developers, especially when working with complex mappings where the mapping debugger adds the most value.

1.3.5.14 New JDeveloper-Style User Interface

The Oracle Warehouse Builder Design Center user interface has been updated to use the Fusion Client Platform, the same core Integrated Development Environment (IDE) platform as Oracle JDeveloper and Oracle SQL Developer.

The advantages of this user interface include:

- More efficient and flexible use of screen real estate.

- Support for opening multiple editors of the same type, for example, editing several ETL mappings at once in different windows.

- More consistent behavior across different parts of the OWB user interface.

This change brings Oracle Warehouse Builder Design Center in line with other development tools from Oracle. Developers experience increased productivity in the Oracle Warehouse Builder environment, which now benefits from the usability research behind the Fusion Client Platform and consistency with other Oracle products.

1.3.5.17 Repository Browser Changes

The Repository Browser has been updated to support foldering, expose the new types of metadata associated with the release 11.2 feature set, and support OC4J 10.3.3.

These changes improve Oracle Warehouse Builder manageability.

1.3.5.18 Simplified Oracle Warehouse Builder Repository Upgrades

The repository upgrade automatically upgrades an Oracle Warehouse Builder (OWB) repository to the current release with less user intervention.

This feature simplifies the task of upgrading from one release to the next.

1.3.5.19 Support for Extracting Data From Tables Containing LONG Data Type

Oracle Warehouse Builder can now generate SQL*Plus code to extract data from database schemas supporting the deprecated LONG data type, such as occurs in PeopleSoft application data sources.

Support for LONG data types used in PeopleSoft data enables OWB users to integrate more effectively with PeopleSoft data or any other data source that uses the LONG data type.

1.3.5.20 Support for Subqueries in Join Operator

The join operator in Oracle Warehouse Builder (OWB) now supports several new behaviors related to the use of subqueries in joins:

- Specifying subqueries using EXISTS, NOT EXISTS, IN, and NOT IN.

- Specifying outer joins using the input role instead of the + (plus) sign.

- Generating ANSI SQL syntax for all join types instead of only outer joins.

More flexible handling for join operations improves developer productivity and makes possible more flexible data transformations.

1.4 Clustering

The following sections describe new clustering features for Oracle Database 11g Release 2 (11.2).

1.4.1 Oracle Real Application Clusters Ease-of-Use

- Faster relocation of services on node failure.

- Support for up to 5 copies of the OCR for improved availability of the cluster.

- Storage of OCR in Automatic Storage Management (ASM).

The tools to manage the OCR have changed to support the new management options.

These enhancements improve performance in Oracle Clusterware and Oracle Real Application Clusters environments and provide easier management of the cluster through consistent storage management automation

See Also:

Oracle Clusterware Administration and Deployment Guide for details

1.4.1.6 Grid Plug and Play (GPnP)

Grid Plug and Play (GPnP) eliminates per-node configuration data and the need for explicit add and delete nodes steps. This allows a system administrator to take a template system image and run it on a new node with no further configuration. This removes many manual operations, reduces the opportunity for errors, and encourages configurations that can be changed easily. Removal of the per-node configuration makes the nodes easier to replace, because they do not need to contain individually-managed state.

Grid Plug and Play reduces the cost of installing, configuring, and managing database nodes by making their per-node state disposable. It allows nodes to be easily replaced with regenerated state.

See Also:

Oracle Grid Infrastructure Installation Guide for details

1.4.1.7 Oracle Restart

Oracle Restart improves the availability of your single-instance Oracle database. Oracle Restart automatically restarts the database instance, the Automatic Storage Management (ASM) instance, the listener, and other components after a hardware or software failure or whenever your database host computer restarts. Server Control (SRVCTL) is the command line interface to manage Oracle processes that are managed by Oracle Restart on a standalone server.

This feature provides improved reliability and automated management of a single-instance Oracle database and the management of any process or application running on the database server.

See Also:

Oracle Database Administrator's Guide for details

1.4.1.8 Policy-Based Cluster and Capacity Management

Oracle Clusterware allocates and reassigns capacity based on policies defined by you. This enables faster resource failover and dynamic capacity assignment using a policy-based management.

Policy-Based Cluster and Capacity Management allows the efficient allocation of all kinds of applications in the cluster. Various applications can be hosted on a shared infrastructure being isolated regarding their resource consumption by policies and, therefore, behave as if they were deployed in single system environments.

See Also:

Oracle Clusterware Administration and Deployment Guide for details

1.4.1.9 Improved Clusterware Resource Modeling

In this release, there are now more options for managing all types of applications and creating dependencies among them using Oracle Clusterware.

Improved Clusterware Resource Modeling enables a granular definition of dependencies among applications or processes to manage them as one entity.

See Also:

Oracle Clusterware Administration and Deployment Guide for details

1.4.1.10 Role-Separated Management

Role-separated management for Oracle Clusterware allows certain administrative tasks to be delegated to different people, representing different roles in the company. It is based on the idea of a clusterware administrator. The administrator may grant administrative tasks on a per resource basis. For example, if two databases are placed into the same cluster, the clusterware administrator can manage both databases in the cluster. But, the clusterware administrator may decide to grant different administrative privileges to each DBA responsible for one of those databases.

Role-separated management allows multiple applications and databases to share the same cluster and hardware resources, but ensures that different administration groups do not interfere with each other.

See Also:

Oracle Clusterware Administration and Deployment Guide for details

1.4.1.11 Agent Development Framework

Oracle Clusterware provides an agent framework for managing all kinds of applications with Oracle Clusterware. Using the agent framework provides optimized application startup, checking, and stopping based on user-defined scripts.

Making it easy to protect applications with Oracle Clusterware reduces costs allowing you to efficiently enable high availability for applications.

Oracle Database SQL Language Reference for details

1.9 Security

The new features discussed in the following section cover areas that include encryption and auditing. Significant new encryption key management functionality has been introduced in Oracle Database 11g Release 2 to enable complete integration with Hardware Security Modules and increased performance for Transparent Data Encryption. Audit Management has been simplified through the introduction of a new package for managing audit data on the Oracle database.

1.9.1 Audit Data Management

Simplify the management of audit data created by the Oracle Database to facilitate compliance with various privacy and compliance mandates such as SOX, HIPAA, and PCI.

1.9.1.1 Audit Trail Cleanup

Audit Trail Cleanup provides the ability to manage the Oracle database audit trail by:

- Automating the periodic deletion of audit records from the database tables and operating system files after they have been securely backed up or are no longer needed.

- Controlling the size and age of the audit trail written to operating system files before a new operating system audit trail file is created.

- Moving the database audit trail tables out of the SYSTEM tablespace to a different tablespace.

Audit Trail Cleanup reduces the time and cost required to manage the Oracle database audit content. It enables you to dedicate an optimized tablespace for audit records and move the audit tables out of the SYSTEM tablespace for improved performance. In addition, it provides automated deletion of audit records from the database tables and operating system files.

1.9.2 Encryption Key Management

Encryption key management provides the ability to change the master key associated with transparent data encryption (TDE) encrypted tablespaces. The tablespace master key is used to encrypt the encryption keys associated with individual tablespaces. This is commonly referred to as a 2-tier key architecture. Prior to Oracle Database 11g Release 2 (11.2), changing the master key was only possible when using TDE column encryption.

1.9.2.1 Tablespace Master Key Rekey

In Oracle Database 11g Release 2 (11.2), Oracle Advanced Security capability allows customers to change the master key used to protect the encryption keys used to encrypt Oracle tablespaces.

Industry initiatives, such as the Payment Card Industry Data Security Standard (PCI DSS), mandate periodic rotation of encryption keys associated with credit card data. This support is now available in this release.

1.10 Server Manageability

The following sections describe server manageability features for Oracle Database 11g Release 2 (11.2).

1.10.1 Automatic Storage Management for All Data

These features extend the capabilities of Automatic Storage Management (ASM) to support all types of data including database files, clusterware files, and file system data such as Oracle homes and binaries.

The following sections describe ASM features.

1.10.1.1 ASM Cluster File System (ACFS)

The ASM Cluster File System (ACFS) extends Automatic Storage Management (ASM) by providing a robust, modern, general purpose file system for files beyond the Oracle database files. ACFS provides support for files such as Oracle binaries, report files, trace files, alert logs, and other application data files. With the addition of the Oracle ASM Cluster File System, ASM becomes a complete storage management solution for both Oracle database and non-database files.

ACFS supports large files with 64-bit file and file system data structure sizes leading to exabyte-capable file and file system capacities. ACFS scales to hundreds of nodes and uses extent-based storage allocation for improved performance. A log-based metadata transaction engine is used for file system integrity and fast recovery. The ACFS on-disk structure supports endian neutral metadata. ACFS file systems can be exported to remote clients through industry standard protocols such as NFS and CIFS.

Oracle ASM Cluster File System (ACFS) complements and leverages Automatic Storage Management (ASM) and provides a general purpose journaling file system for storing and managing non-Oracle database files. This eliminates the need for expensive third-party cluster file system solutions while streamlining, automating and simplifying all file type management in a single node as well as Oracle RAC and Oracle Grid infrastructure for a cluster computing environments.

ACFS supports dynamic file system expansion and contraction without any downtime. ACFS is highly available leveraging the ASM mirroring and striping features in addition to hardware Redundant Array of Inexpensive Disks (RAID) functionality.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

1.10.1.2 ASM Dynamic Volume Manager (DVM)

The ASM Dynamic Volume Manager (DVM) is a kernel-loadable device driver that provides a standard device driver interface to clients (for example, ACFS). File systems or other processes can do I/O to this device driver as they would to any other disk device driver on the system. DVM is the primary I/O interface for ACFS to perform I/O and build a file system leveraging ASM as a volume manager. DVM is loaded on ASM start up. The device driver is cluster-aware and communicates with ASM for extent map information, extent rebalancing, and I/O failures.

The ASM Dynamic Volume Manager (DVM) provides a standard I/O interface allowing general purpose file systems to leverage the full functionality of ASM as a volume manager. Oracle database files as well as non-Oracle database files, for example Oracle binaries, can now reside on ACFS eliminating the need for third-party file systems or volume managers to host general purpose files.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

1.10.1.3 ASM FS Snapshot

ASM FS Snapshot is a point-in-time copy of a file system and can provide up to 64 snapshot images. ASM FS Snapshot performs fast creation of persistent ASM FS images at a specific point-in-time with low overhead leveraging the Copy on Write technology.

Read-only ASM FS Snapshots can be generated on an interval basis. They may reside in existing ASM FS storage or in an additional storage device and persist following a system restart.

Even as the file system changes, the snapshot does not, giving you the ability to view the file system as it was at the time the snapshot was created. Initially, snapshots are read-only, which preserves their point-in-time capture. The following are the benefits of ASM FS Snapshots:

- ASM FS Snapshots can be used as a source for backup. The original file system can continue to change but the static nature of the snapshot makes them ideal as a source for backup without keeping the original file system offline.

- ASM FS Snapshots can be used as a means for you to recover accidentally deleted or modified files.

- ASM FS Snapshots can be used as a source for data mining or report applications which need to work on a static, point-in-time data set.

Oracle Automatic Storage Management Administrator's Guide for details

1.10.1.4 Oracle Cluster Registry (OCR) and Voting Disk on ASM

Automatic Storage Management (ASM) disks are used to store the Oracle Cluster Registry (OCR) and the voting disks. ASM Partnership and Status Table (PST) is replicated on multiple disks and is extended to store the OCR. Consequently, the OCR tolerates loss of the same number of disks as the underlying disk group. OCR is relocated in response to disk failures.

ASM reserves a number of blocks at a fixed location of every ASM disk for storing the voting disk. Should the disk holding the voting disk fail, ASM selects another disk to store this data.

Storing the OCR and the voting disk on ASM eliminates the need to use expensive third-party cluster volume managers or deal with the complexity of managing disk partitions for OCR and voting disks in Oracle RAC configurations.

Oracle Grid Infrastructure Installation Guide for Linux for details

1.10.1.5 ASM Intelligent Data Placement

Disk drives have higher transfer rates and bytes per track on the outer tracks. This makes it preferable to keep the hotter data closer to the edge of the disk; that is, the lower numbered blocks. This feature enables ASM to identify higher performance disk regions. Most frequently accessed ASM files can be marked to be moved into the hot region and take advantage of higher I/O performance (for example, hot tablespaces and indices) and able to better meet the application I/O demand. This feature is only applicable when whole physical disks are presented to ASM versus local unit numbers (LUN).

Most frequently accessed Oracle database files in ASM disk groups (ASM files) can be placed in hot disk regions to deliver higher bandwidth and reduce seek latency to meet the application I/O performance requirements.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

1.10.1.6 ASM Storage Management Configuration Assistant

ASM Storage Management Configuration Assistant was previously known as Enterprise Manager Integration with ASM Optimal Disk Placement.

This release now allows the configuration, monitoring, and management of Optimal Disk Placement with Enterprise Manager which is the graphical user interface (GUI) for management.

This GUI manages ASM which makes storage management easier in an Oracle environment.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

1.10.1.7 Automatic Storage Management (ASM) File Access Control

Automatic Storage Management (ASM) on UNIX platforms implements access control on its files to isolate different database instances from each other and prevent unauthorized access. ASM implements new SQL statements to grant, modify, and deny file permissions. The new security model and syntax is coherent with those already implemented for the objects represented in Oracle Database.

Multiple database instances can store ASM files in the same disk group and, therefore, are able to consolidate multiple databases with security. This prevents unauthorized database instances from accessing or overwriting each other's files.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

1.10.1.8 ASMCMD Command Extensions

The ASMCMD tool is extended to include management of ASM disks, disk groups, and ASM instance in addition to managing ASM files.

Oracle Database 2 Day + Real Application Clusters Guide for details

1.10.2.3 Automatic Patching of Time Stamp With Time Zone Data

Time stamp with time zone data could become stale in the database tables when the time zone version file is updated. Today, users have to manually fix the affected data. This feature updates the system and user data transparently with minimal downtime and provides automatic and transparent patching of time stamp with time zone data whenever a time zone file is updated.

Also, when a server time zone version is patched, all of the clients that communicate with the server need to be patched as well. With this feature, OCI, JDBC, Pro*C, and SQL*Plus clients can now continue to work with the server without having to update their client-side files.

This new feature provides automatic and transparent patching of time stamp with time zone data whenever a time zone file is updated.

See Also:

Oracle Database Globalization Support Guide for details

1.10.2.4 Prevent Data Loss for Time Zone with Local Time Zone Data Type

This feature makes TIMESTAMP WITH TIME ZONE data type immune to Daylight Saving Time (DST) changes and reduces the overhead of patching time zone data file and upgrading data on disk.

The benefit of this feature is the elimination of the processing cost and the complexity of maintaining TIMESTAMP WITH TIME ZONE data type whenever there are new changes to DST transition rule and time zones.

See Also:

Oracle Call Interface Programmer's Guide for details

1.10.2.5 Segment Creation on Demand

The initial segment creation for nonpartitioned tables and indexes can be delayed until data is first inserted into an object.

Several prepackaged applications are delivered with large schemas containing many tables and indexes. Depending on the module usage, only a subset of these objects are really being used. With delayed segment creation, empty database objects do not consume any space, reducing the installation footprint and speeding up the installation.

See Also:

Oracle Database SQL Language Reference for details

1.10.2.6 Zero-Size Unusable Indexes and Index Partitions

Unusable indexes and index partitions no longer consume space in the database because they become segmentless.

Unusable indexes and index segments are not usable for any data access. Any space allocated by this unusable (dead) object is freed as soon as an object is marked unusable.

See Also:

Oracle Database Administrator's Guide for details

1.10.2.7 Metadata SXML Comparison Tool

The Metadata API has been enhanced to provide a cross database comparison tool to compare object metadata of the same type from different databases. This comparison depends on an alternate XML representation, called SXML. Full XML is typically complex and opaque. In contrast, SXML is somewhat simplified and more closely maps to the SQL creation DDL. These SXML documents provide the building blocks for the new comparison tool in which two SXML documents of the same type can be compared and a new SXML document is produced which describes their differences.

This feature enables users to compare objects between databases to identify drift (that is, metadata changes over time) in objects of the same type.

See Also:

Oracle Database PL/SQL Packages and Types Reference for details

1.10.2.8 Compare Period Report

A Replay Compare Period Report performs a high-level comparison of workload replay to its capture or to another replay of the same capture. The Replay Compare Period report contains a summary of the most important changes between the two runs in terms of performance, errors and data divergence. This makes it easier for Database Replay users to understand and test the impact of system changes.

Replay Compare Period Report simplifies understanding and assessment of the impact of system change in testing by providing summarized information on how the replay performed versus capture or other replays in terms of performance, errors and divergence.

1.10.2.9 Compare SQL Tuning Sets

Compare SQL Tuning Set feature of the SQL Performance Analyzer allows:

- Building a trial from SQL Tuning Set (STS).

- Comparison of two such trials built from two different STSs. A detailed comparison report including any new or missing SQL statements in one and not in another trial and any plan changes noticed in the compared trials is compiled.

Compare SQL Tuning Sets makes it possible for Database Replay users to perform SQL-centric analysis through the SQL Performance Analyzer report. The two STSs are captured as follows:

- One during workload capture on production.

- And, the other during replay on the test system.

Then, the two STSs are used to generate the SPA report.

Compare STS feature can also be used in non-Database Replay scenarios where customers already have existing test scripts and can capture the SQL into two STSs; one for before system change and one for after.

Compare SQL Tuning Sets feature simplifies assessment of system changes by providing detailed SQL-centric analysis when using Database Replay or other load testing mechanisms.

This release includes the following enhancements to SQL Tuning Advisor:

- SQL Tuning Advisor may recommend accepting a profile that uses the Automatic Degree of Parallelism (Auto DOP) feature. A parallel query profile is only recommended when the original plan is serial and when parallel execution can significantly reduce the elapsed time for a long-running query.

- While tuning a SQL statement, SQL Tuning Advisor searches real-time and historical performance data for alternative execution plans for the statement. If plans other than the original plan exist, then SQL Tuning Advisor reports an alternative plan finding.

- You can transport a SQL tuning set to any database created in Oracle Database 10g (Release 2) or later. This technique is useful when using SQL Performance Analyzer to tune regressions on a test database.

These features are introduced to enhance the capabilities of the SQL Tuning Advisor. The newest version can recommend alternative plans that were seen at some time in the past, in case they perform better, as well as recommending queries to run in parallel if that is beneficial for the total runtime of each query.

The STS export to old releases is designed to help customers with upgrades so that they are using the most recent version of the database software.

1.11 Unstructured Data Management

The new features in the following sections describe the significant performance, developer productivity and advanced capabilities in Oracle Multimedia, Oracle Spatial, Oracle Database SecureFiles, and XML Database.

1.11.1 Enhanced Oracle Multimedia and DICOM Support

The following sections describe the new features and capabilities for Oracle Multimedia and Digital Imaging and Communications in Medicine (DICOM).

1.11.1.1 Attribute Extraction of Requested Attributes Only

Oracle Multimedia now allows extraction of a subset of DICOM metadata attributes as requested by a user or an application, without first extracting all DICOM attributes from the DICOM content.

DICOM content can contain hundreds of metadata attributes. Often only a few attributes are required for indexing, searching and partitioning. Extraction of a subset eliminates the previous requirement of extracting all attributes thus improving performance.

See Also:

Oracle Multimedia DICOM Developer's Guide for details

1.11.1.2 Client-Side DICOM Attribute Extraction

Oracle Multimedia now allows DICOM metadata extraction to be performed outside the database by a client tool or in the middle-tier.

This enables extraction of DICOM metadata before the data is loaded into the database, facilitating metadata-based partitioning of DICOM data in the database.

See Also:

Oracle Multimedia DICOM Developer's Guide for details

1.11.1.3 DICOM Enhancements

The following enhancements have been added to Oracle Multimedia:

- Metadata extraction
Any portion of a DICOM attribute can now be extracted (for example, extraction of the last name portion of the patient name attribute).

- Constraint definitions
Validation of recursive structures such as DICOM Structured Reports can now be specified, and new FOR EACH syntax has been added to allow iteration through all the components in a single predicate.

- DICOM content processing:

- DEFLATE transfer syntax support has been added.

- RLE compression is now supported.

- Encoding of multi-bit monochrome images is now supported.

- YBR photometric interpretation is now supported.

- DICOM to AVI and DICOM to MPEG conversions are now supported.

- MPEG encapsulated into DICOM format is now supported.

These new features allow more complete and powerful operations on DICOM data that include:

- Flexible extraction of metadata from DICOM data.

- Support for DICOM Structured Reports.

- Presentation of DICOM videos in any browser, without requiring specific DICOM support in the browser.

1.11.2 Enhanced Oracle Spatial Support

The following sections describe new features in Oracle Spatial support for 3D, geocoder, routing engine, GeoRaster, and network data model.

1.11.2.1 3D Visualization Framework

This release includes a set of metadata tables to describe themes, scenes, textures, viewpoints, light sources, non-geographic data, and other elements used to visualize three-dimensional (3D) content. It also delivers a number of performance improvements to the 3D analysis operations.

This metadata support for 3D content enables a consistent way to combine all 3D, raster, vector, and non-geometric data into a unified visualization framework. Information may be logically grouped into themes to simplify the development, analysis, use, and maintenance of 3D applications.

See Also:

Oracle Spatial Developer's Guide for details

1.11.2.2 Network Data Model Enhancements

Oracle Spatial network data model (NDM) delivers numerous enhancements. These include a 30-50% more memory-efficient representation of user attribute data associated with the network, many additional highly requested path and subpath analysis functions such as traveling sales person (TSP), hierarchical shortest path (HSP), and K-shortest path (KSP).

This release also allows the logical partitioning of networks based on metrics appropriate to the application. For analysis of data associated with the network, NDM has added a network buffer feature to derive the zone of influence with coverage and cost information and a "minimum cost polygon" to allow for the association of geographic points of interest or coverages with a network defined region.

These enhancements allow NDM to support more completely a wider range of requirements found in utility networks, logistics and other applications dependent upon network-based analysis.

Oracle Spatial Topology and Network Data Models Developer's Guide for details

1.11.2.3 New GeoRaster JAVA API

With Oracle Spatial, there is a new Java application programming interface (API) to all functions currently available in the existing PL/SQL interface. These include support for all the search, analysis and raster management features in Oracle Spatial GeoRaster.

In addition, this API includes calls to support the development of extraction, transformation, and loading (ETL) tools, Web applications and raster processing applications.

This new feature simplifies the development of Java applications that use, access, and manipulate raster and gridded data sets stored in Oracle Spatial.

See Also:

Oracle Spatial GeoRaster Developer's Guide for details

1.11.2.4 Raster Reprojections and Ground Control Point-Based (GCP) Georeferencing

Oracle Spatial currently includes support for over 4,000 coordinate systems when using vector data. Oracle GeoRaster now supports the reprojection of imagery to any of these 4,000 plus Oracle Spatial coordinate systems.

In this release the GeoRaster feature also supports native storage and georeferencing of Ground Control Point (GCP) data.

These capabilities remove the requirement for third-party tools currently required when using vector data and raster imagery in different coordinate systems. Oracle Spatial can now be used to perform these reprojections.

Ground Control Point-based georeferencing is used in data collection and processing applications. This native GCP storage and georeferencing can be used to georeference raw (non-rectified) and processed (rectified) raster data.

See Also:

Oracle Spatial GeoRaster Developer's Guide for details

1.11.2.5 Routing and Geocoding Enhancements

With this release, the Oracle Spatial routing engine is based on the network data model. This increases the ability of Oracle to support the restrictions and conditions required for advanced routing applications.

The Oracle Spatial 11.2 geocoder, in addition to the support for standard address geocoding based on interpolation, now supports point-based geocoding where data sets include the exact location of addresses, intersections, and points of interest.

Oracle Spatial now supports truck routing data sets to produce driving directions that include restrictions based on roads, weight, height, time of day, and other conditions applied to commercial and logistics applications.

Point-based geocoding is becoming increasingly popular because it allows for more accurate results and can be used in situations where interpolation is not possible.

1.11.3 Oracle SecureFiles

The following sections describe improvements in Oracle SecureFiles.

1.11.3.1 Database File System (DBFS)

The Oracle Database File System (DBFS) enables the database to be used as a POSIX-compatible file system on Linux. This feature includes a PL/SQL package on the database server that enables the DBFS server functionality and a Linux client for DBFS (dbfs_client). The dbfs_client client is a utility that enables mounting of a DBFS file system as a mount point on Linux. It provides the mapping from file system operations to database operations. The dbfs_client client runs completely in user space and interacts with the kernel through the FUSE library infrastructure.

DBFS Hierarchical Store provides an easy and application-transparent way to archive SecureFiles data that is stored in DBFS file systems to secondary storage tiers such as tape and storage clouds, using DBFS Links. It also allows archived data to be dearchived and brought back into the database on demand.

DBFS makes it easy for files to be accessed by database applications, and for file-based tools to access files stored in the database. With DBFS, all important file data can be seamlessly stored in an Oracle database, providing the benefits of security, backup, performance, and scalability that are standard with the Oracle Database.

SecureFiles is a high performance solution for storing files or unstructured data in Oracle Database. Customers often need to store these files for long periods of time for business or compliance reasons. Consequently, customers are looking to transfer files to cheaper forms of storage in an application-transparent manner to reduce manageability and administration overhead. DBFS Hierarchical Store provides a seamless, automatic, and transparent way to archive cold file data to inexpensive storage.

Oracle Database SecureFiles and Large Objects Developer's Guide for details

1.11.3.2 Support for Oracle SecureFiles

Oracle Database 11g Release 2 (11.2) introduces a new compression level for SecureFiles LOBs called COMPRESS LOW. This compression level introduces a lightweight compression option that removes the majority of the CPU cost that is typical with file compression. Compressed SecureFiles at the LOW level now provides a very efficient choice for SecureFiles storage. SecureFiles LOBs compressed at LOW generally consume less CPU than BasicFile (pre-11g Release 1) LOBs, consume less storage than BasicFile LOBs and typically makes the application run faster because of reduced disk I/O.

1.11.4 Oracle XML DB Scale and Performance Improvements

The following sections address key customer requirements in the area of scalability and performance by delivering partitioning of XML tables, scaling on registering large XML Schemata, significant improvements in XML indexing and query performance for common real-world workloads, and significant improvements in performance of repository operations.

1.11.4.1 Binary XML Enhancements

This release includes support for partitioning of binary XMLType table and relation tables containing binary XML columns, where the partition key is derived from the XML content. Also included are guidelines on how to optimize performance of binary XML operations.

This new feature allows Oracle partitioning to be used with binary XML content, thereby allowing large volumes of XML data to be managed effectively.

See Also:

Oracle XML DB Developer's Guide for details

1.11.4.2 Oracle XML DB Repository Performance Improvements and Guidelines

1.11.4.3 XMLIndex Enhancements

This release includes improvements to the ability for Oracle to index unstructured, semi-structured, and highly-structured XML documents stored using binary XML. Also included is support for partitioned indexes and parallel operations. These enhancements incorporate all features of existing XMLIndex and XMLTable Index into a single unified index.

The benefits are high performance query, fragments, and scalar extraction operations on schema and schema-less binary XML storage.

See Also:

Oracle XML DB Developer's Guide for details

1.11.4.4 XMLType Partitioning

This feature allows partitioning of the nested tables that are used to manage collections of child elements when storing XML documents using object-based persistence in conjunction with nested tables.

XMLType partitioning enables all the advanced features of the Oracle partitioning option to be used to manage XMLType data.

2 Oracle Database 11g Release 2 (11.2.0.2) New Features

This chapter contains descriptions of all of the features that are new to Oracle Database 11g Release 2 (11.2.0.2). This chapter contains the following sections:

- General

- ACFS Improvements

- Quality of Service (QoS) Management

- Database Replay

- Management

2.1 General

The following sections describe the new features for Oracle Database 11g Release 2 (11.2.0.2).

2.1.1 General

The following sections provide information on new features for 11.2.0.2.

2.1.1.1 Control File Updates Can Be Disabled During NOLOGGING Operations

Parameter DB_UNRECOVERABLE_SCN_TRACKING = [ TRUE | FALSE ] can be used to turn off control file writes to update fields that track the highest unrecoverable SCN and Time during a NOLOGGING direct path operation.

Performance of the NOLOGGING load operation could be limited by the control file write I/O.

2.1.1.2 New Package for Configuring Automatic SQL Tuning

A new PL/SQL package, DBMS_AUTO_SQLTUNE, has been introduced to provide more restrictive access to the Automatic SQL Tuning feature.

With this package, access to Automatic SQL Tuning can be restricted to DBAs so that only they can change its configuration settings that effect run-time behavior of the query optimizer, such as enabling or disabling automatic SQL profile creation.

See Also:

Oracle Database Performance Tuning Guide for details

2.1.1.3 Enhanced Security for DBMS_SCHEDULER E-Mail Notification

Encryption and authentication have been added to the Oracle Scheduler's e-mail notification feature.

E-mail notification on job failures was added in 11.2.0.1, but it did not support those e-mail servers that require either encryption or authentication. This feature adds this support in 11.2.0.2.

See Also:

Oracle Database Administrator's Guide for details

2.1.1.4 Enhanced TRUNCATE Functionality

While truncating a table or partition, you can now specify whether or not to keep any segments. Truncating a table or partition with the new extended syntax removes all segments and does not use any space until new data is inserted.

All allocated space in a database can now be reclaimed by truncating tables or partitions with the new extended syntax, optimizing the space foot print of any application.

See Also:

Oracle Database Administrator's Guide for details

2.1.1.5 Improvements to Reduce the Occurrences of "Existing State of Packages Discarded" Errors

When the body of a stateful package is recompiled by session A, then a different session B which has already instantiated that package will experience the ORA-04068 existing state of packages… has been discarded family of errors on its next reference to that package following the recompilation. The result is severe disruption for the user of session B.

Two improvements in this release now reduce the likelihood of these ORA-04068 errors:

- A package, whose global variables is marked constant; and where the initial value can be computed at compile time, is now considered to be stateless.

- The new procedure DBMS_SESSION.RESET_SELF(), whose invocation must be in the package of interest, allows you to preempt the problem when it is safe to reinitialize the package state.

The advantage is that packages (and especially those that are not editioned) can be "hot patched" (that is, recompiled) when other sessions are using them with a greatly reduced likelihood of disrupting those sessions.

Oracle Database PL/SQL Language Reference for details

2.1.1.6 Support for In-Place Upgrade of Clients

Both in-place and out-of-place upgrades are supported for client installations.

You now have the option of doing in-place client upgrades reducing the need for extra storage and simplifying the installation process.

See Also:

Oracle Database Client Installation Guide for Linux for details

2.1.1.7 Maintenance Package for Segment Creation on Demand

Customers can manage the space allocation of any application through extended functionality of the DBMS_SPACE package. This package can be used to remove the segments for all empty tables in a database, a user schema, or for specific tables. This package also provides the opposite functionality to materialize all segments for empty tables or partitions with deferred segment creation

The explicit management of deferred segment creation enables you to take advantage of this functionality at any given point in time, even after table or partition creation. This is especially useful for systems that were upgraded in-place and makes a re-creation of all empty objects unnecessary.

See Also:

Oracle Database Administrator's Guide for details

2.1.1.8 Maximum CPU Utilization Limit

Resource Manager provides a new directive called MAX_UTILIZATION_LIMIT that allows you to place a hard limit on the amount of CPU utilized by a consumer group.

The MAX_UTILIZATION_LIMIT directive is useful for limiting the CPU utilization of low priority workloads. This directive is also useful for providing more consistent performance for the workload in a consumer group, and it helps to build systems where end users experience consistent response times for each database operation.

See Also:

Oracle Database Administrator's Guide for details

2.1.1.9 Name Matching

This feature provides an efficient method for matching proper names (and words) that take a query as input and returns a ranked list of matches. The new operator NDATA is introduced for this functionality.

In today's multicultural society, a person accustomed to the spelling rules of one demographic may have difficulty applying those same rules to a name originating from a different culture.

Name matching provides a solution to match proper names that might differ in spelling due to orthographic variation.

See Also:

Oracle Text Reference for details

2.1.1.10 Named Entity Extraction

Entity extraction is the recognition of entity names (people and organizations), places, temporal expressions, and types of numerical expressions such as currencies and measures.

The goal of entity extraction is to identify instances of a particular pre-specified class of entities in textual documents.

The benefit is to produce a "structured" view of a document that can later be used for text or data mining and more comprehensive intelligence analysis.

See Also:

Oracle Text Reference for details

2.1.1.11 Default Size of First Extent of Any New Segment for a Partitioned Table Has Changed

The default size of the first extent of any new segment for a partitioned table is now 8 MB instead of 64 K.

The goal is to improve I/O performance. However, under certain circumstances, loading a table will take significantly more disk space.

See Also:

Oracle Database Administrator's Guide for details

2.1.1.12 Parallel Statement Queuing

Parallel Statement Queuing ensures all statements run on a system get the appropriate parallel resources to perform well by allowing you to ensure that a system is neither overwhelmed nor starved for parallel server processes. Queuing can be implemented per resource group and allows for both prioritization of statements and the above mentioned management of a parallel workload. Parallel Statement Queuing works in conjunction with Automatic Degree of Parallelism.

Data Warehouses are evolving into systems that support both operational environments and the more classic strategic data warehouse workloads. These mixed workloads require active workload management. One of these resources that should be managed as part of the workload management process is the use of Parallel Server Processes. Parallel server resources are allocated by Automatic Degree of Parallelism (DOP). Statement queuing is then used to ensure that each statement can run with the optimal DOP within the system limits. Allowing each statement to run with the optimal DOP allows a system to:

- Perform well overall and avoid large wait times on system resources.

- Utilize all resources in an optimal manner without trashing the system in peak times or due to runaway queries.

- Balance overall performance to be much more predictable.

- Allocate appropriate resources based on policies, not based on user abuse.

2.1.1.13 PMML Import

This release adds support for importing external data mining models (linear and binary logistic regression) using the Data Mining Group Predictive Model Markup Language (PMML) standard. The imported models become native Oracle Data Mining (ODM) models capable of Exadata offload.

If you use an external data mining product to generate models, you could encounter difficulty when deploying those models into their production databases. The current process of deploying such models is expensive, error prone, and non-performant. This feature streamlines the movement of external models into production Oracle systems and leverages optimized performance of the ODM option.

Oracle Database PL/SQL Packages and Types Reference for details

2.1.1.14 Result Set Interface

The client interface CTX_QUERY.RESULT_SET executes a query and generates a result set. The components of the result set are:

- Documents.

- Support order by SDATA.

- A total estimated count of number of matching documents.

- A count, broken down by metadata value, of matching documents in each category.

A page of search results consist of many disparate elements (for example, metadata of the first few documents, snippet, total hit counts, and so on). Instead of accessing the database to construct bits of the search results, it would be useful to have a clean result set mechanism. The result set interface is able to produce the various kinds of data needed for a page of search results all at once, improving performance by sharing overhead. The result set interface can also return data views which are difficult to express in SQL, such as top n by category queries.

See Also:

Oracle Text Application Developer's Guide for details

2.1.1.15 Segment Creation On Demand for Partitioned Tables

The initial segment creation for partitioned tables and indexes can be deferred until data is first inserted into an object. Individual partitions will not be physically created before data is inserted for the first time.

Several prepackaged applications are delivered with large schemas containing many partitioned tables and indexes. With deferred segment creation for partitioned tables, empty database objects do not consume any space, reducing the installation footprint and speeding up the installation.

See Also:

Oracle Database Administrator's Guide for details

2.1.1.16 Simplification of XML and XQuery Interfaces

This feature extends the XQuery 1.0 standard's operator fn:doc and fn:collection to allow direct access to collections of XML documents stored in the database.

Direct access to XML content in tables and views is provided by extending fn:doc and fn:collection to support DBUri-style paths through the pseudo protocol xdb://.

Simplification of Oracle XML and XQuery interfaces provides standard mechanisms, allows building of portable XML applications that are easier to maintain, and deprecates redundant or unused functionality.

2.1.1.17 SMTP Authentication

Starting with this release, you can configure the UTL_SMTP PL/SQL package for use on both Transport Layer Security (TLS) and Secure Sockets Layer (SSL) servers."

This allows the package to be used to send to SMTP servers that require authentication to combat spam.

See Also:

Oracle Database PL/SQL Packages and Types Reference for details

2.1.1.18 SMTP Encryption

UTL_SMTP is extended in this release to provide Secure Sockets Layer (SSL) and Transport Layer Security (TLS) support.

This allows the package to be used to send to SMTP servers using SSL and TLS to ensure channel integrity.

See Also:

Oracle Database PL/SQL Packages and Types Reference for details

2.1.1.19 SPA Support for Active Data Guard Environment

If you are using Oracle Active Data Guard physical standby database, you already have full dataset or clone or both of the production environment that can be leveraged for testing with SQL Performance Analyzer (SPA). Using remote test execution SPA trial method, you can connect to a physical standby database in read-only mode and use it for testing. The physical standby database continues to be in read-only and standby mode (changes are being applied) during SPA testing. The SPA analysis and reports are available from the remote database that is orchestrating the SPA trials. The orchestrating database (SPA system) can be the primary database or any remote database running Oracle Database 11g and higher releases.

This feature allows customers to leverage existing Active Data Guard physical standby databases for SQL Performance Analyzer Testing.

See Also:

Oracle Database Real Application Testing User's Guide for details

2.1.1.20 The EDITION Attribute of a Database Service

The EDITION attribute of a database service specifies the initial session edition for a session that is started using that service. If the program that creates a new session does not specify the initial session, then the edition name specified by the service is used. If the service does not specify the edition name, then the initial session edition is the database default edition.

When an edition-based redefinition exercise is implemented to support hot rollover, some clients to the database will want to use the pre-upgrade edition and others will want to use the post-upgrade edition. In this scenario, the database default edition is insufficient because, by definition, it denotes a single edition. The EDITION attribute of a database service provides a way to allow the client to specify the edition it wants using environment data rather than by changing the client code.

See Also:

Oracle Database PL/SQL Packages and Types Reference for details

2.1.1.21 Using Binary XML with SecureFiles as the XMLType Default Storage

In this release, the default storage model has changed for XMLType from STORE AS CLOB to STORE AS SECURE FILE BINARY XML. This affects the storage used when an explicit STORE AS clause is not supplied when creating an XMLType table or column. Not specifying a STORE AS CLAUSE indicates that it is left to the database to determine what the optimal storage model should be.

Prior to database release 11.2.0.2, the default storage model was STORE AS BASICFILE CLOB. In 11.2.0.2, the default is changed to STORE AS SECUREFILE BINARY XML.

This change requires the installation of the XDB feature in order to work correctly. Customers that choose not to install the XDB feature must explicitly add STORE AS CLOB to any DLL statements that create XMLType table or columns to avoid DDL errors. Note that the use of XMLType without having the XDB installed is not a supported configuration as of 11.1.0.1.

No data migration takes place when databases are upgraded to 11.2.0.2.

Binary XML with SecureFiles provides efficient storage, retrieval, and DML capabilities for semi-structured and unstructured XML data. Changing the default storage for XMLType to binary XML with SecureFiles helps customers to adopt best practices.

Oracle XML DB Developer's Guide for details

2.1.1.22 JDBC 4.0 SQLXML

This feature implements the JDBC 4.0 specification of the SQLXML interface for managing the XML data type in the database.

This feature allows Java applications using JDBC-Thin or JDBC-OCI to manage the XML data type in the database, using the standard SQLXML type (java.sql.SQLXML).

See Also:

Oracle Database JDBC Developer's Guide for details

2.1.1.23 ID Key LCRs in XStream

ID key LCRs enable an XStream client application to process changes to rows that include unsupported data types. ID key LCRs do not contain all of the columns for a row change. Instead, they contain the rowid of the changed row, a group of key columns to identify the row in the table, and the data for the scalar columns of the table that are supported by XStream Out. ID key LCRs do not contain columns for unsupported data types.

This feature enables XStream users to capture database changes that cannot be supported using Oracle Streams.

See Also:

Oracle Database XStream Guide for details

2.1.2 ACFS Improvements

The following sections provide information on ACFS improvements for 11.2.0.2.

2.1.2.1 ACFS, ADVM and Snapshots on Solaris and AIX

Oracle ACFS, Oracle ASM Dynamic Volume Manager (Oracle ADVM) and Snapshots were delivered in Oracle Database 11g Release 2 (11.2.0.1) on Windows NT and Linux platforms.

Oracle Database 11g Release 2 (11.2.0.2) now provides a general purpose cluster file system which leverages the capabilities of Oracle ASM on Solaris and AIX platforms.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

2.1.2.2 Oracle ACFS Replication

The Oracle Automatic Storage Management Cluster File System (Oracle ACFS) Replication feature supports asynchronous replication of an ACFS file system from a primary to standby site.

The Oracle ACFS Replication feature allows you to replicate ACFS file systems across the network to another (possibly distant) site. This provides a disaster recovery capability for the file system. This feature can be used in conjunction with Oracle Data Guard to replicate all Oracle data.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

2.1.2.3 Oracle ACFS Security and Encryption Features

Oracle ASM Cluster File System (Oracle ACFS) security feature provides realm-based security for Oracle ACFS.

Oracle ACFS encryption feature enables data stored on disk (data-at-rest) to be encrypted.

Oracle ACFS security feature provides the ability to create realms to specify security policies for users or groups for accessing file system objects. The Oracle ACFS security feature provides a finer-grained access control on top of the access control provided by the operating system.

Oracle ACFS encryption feature provides the ability to keep data in an Oracle ACFS file system in encrypted format to prevent unauthorized use of data in the case of data loss or theft.

See Also:

Oracle Automatic Storage Management Administrator's Guide for details

2.1.2.4 Oracle ACFS Tagging

The Oracle ACFS Tagging feature provides a method for relating a group of files based on a common naming attribute assigned to these files called a tag name.

You can use this feature alone or in conjunction with other features. For example, in conjunction with Oracle ACFS Replication, you can select specific files that you would like to replicate to a different remote cluster site by assigning a unique tag name to them. You would then instruct Oracle ACFS Replication to replicate files based upon this tag name. By using tagging in this respect, the need to replicate entire Oracle ACFS file systems is reduced.

Oracle Automatic Storage Management Administrator's Guide for details

2.1.3 Quality of Service (QoS) Management

A new Quality of Service (QoS) Management Server enables run time management of service levels for hosted database applications on a shared infrastructure by cluster administrators. The goal is to present an easy-to-use, policy-driven management system that ensures meeting service levels if sufficient resources are available and when they are not, allocates resources to the most business critical workloads not meeting their service levels at the expense of the less critical ones.

The following sections describe Quality of Service Management Server features.

2.1.3.1 Database QoS Management Server

The Database Quality of Service (QoS) Management Server allows system administrators to manage application service levels hosted in Oracle Database clusters by correlating accurate run-time performance and resource metrics and analyzing with an expert system to produce recommended resource adjustments to meet policy-based performance objectives.

The Database QoS Management Server enables the pooling of resources to help ensure that, when sufficient resources are available, performance and availability objectives are met, even under demand surges. Managing resource allocations to match performance objectives using a set of predefined policies, the Database QoS Management Server greatly reduces system administrator and DBA time and expertise. By continuously monitoring the system performance based on real demand, it quickly identifies bottlenecks and potential problems that can be corrected before an actual outage occurs. This system cuts time to resolve service level violations as it provides detailed metrics and bottleneck identification along with recommendations for resolution. The end result is the stakeholders trust to share resources thus reducing capital and operational expenses.

Oracle Database Quality of Service Management User's Guide for details

2.1.3.2 Database Quality of Service (QoS) Management Support

To support the Database Quality of Service (QoS) Management Server, the Oracle Database Resource Manager and metrics have been enhanced to support fine-grained performance metrics and now have the ability to manage workloads by user-defined performance classes.

By supporting the Database QoS Management Server, applications sharing a single database or multiple databases within a cluster can be managed discretely to monitor and maintain their service levels. This consolidation reduces hardware, software and management costs while maintaining business objectives.

See Also:

Oracle Database Quality of Service Management User's Guide for details

2.1.3.3 Enterprise Manager QoS Management Integration

The administration of the Database Quality of Service (QoS) Management Server is integrated into the new Cluster Administration section of Enterprise Manager. This is designed as a task-based interface to create policy sets using a wizard, manage application service levels using a dashboard, and monitor performance through historical graphs, logs and alerts.

This feature provides full task-based integration into Enterprise Manager, simplifying the administration tasks necessary to manage database application service levels using the Database QoS Management Server. It both reduces task and troubleshooting time as well as the level of training required thus reducing costs while maintaining application availability.

See Also:

Oracle Database Quality of Service Management User's Guide for details

2.1.3.4 Server Memory Stress Protection for Oracle Clusters

When QoS Management is enabled and managing an Oracle Clusterware server pool, it receives a metrics stream from the Cluster Health Monitor that provides real-time memory data including the amount available, in use, and swapped to disk for each server. Should a node be determined to be under memory stress, the CRS-managed database services are stopped on that node preventing new connections from being created thereby protecting existing sessions. Once the memory stress is relieved (for example, by either existing sessions closing or user intervention), the services are restarted automatically and the listener begins sending opening connections on that server.

Enterprise database servers can run out of available memory due to too many sessions or runaway workloads. This can result in failed transactions or, in extreme cases, a reboot of the server and loss of a valuable resource. Oracle Database QoS Management detects memory pressure in real-time and prevents the addition of new sessions from exhausting available memory thus protecting existing workloads and the availability of the server. This adds a new resource protection capability in managing Service Levels for Oracle RAC database-hosted applications.

2.1.4 Database Replay

The following sections provide information on new Database Replay features for 11.2.0.2.

2.1.4.1 Database Replay SQL Performance Analyzer (SPA) Integration

This feature allows you to perform SQL Tuning Set (STS) capture and workload capture or replay at the same time in a single process. STS is automatically exported when the AWR data for the capture or replay is exported into the specified directory object. By integrating SPA and Database Replay, you can analyze SQL-centric issues in the workload more easily than if they were to do this manually in separate steps. An SPA report can be generated at the end of workload replay to facilitate SQL-centric analysis. Oracle RAC is not yet supported.

Integration of SPA and Database Replay features provides the ability to perform SQL Tuning Set and workload capture or replay in one process and at the same time. As a result, an SPA report is available to help with SQL-centric analysis when workload replay is done.

2.1.4.2 Database Replay Timeout Function

During workload replay, it is sometimes possible that due to an execution plan, system change or otherwise, a replay call may hang or take a long time. You can specify a replay timeout parameter. If the call exceeds the timeout, that particular call is aborted. This is useful with workloads when one or a few calls result in the workload replay to run too long or hang. Aborting these will still provide a useful workload replay.

Database Replay timeout functionality provides the ability to control how long a long running or runaway replay call will take. Without this functionality, a replay call may take a long time or hang depending on the situation.

Oracle Database Real Application Testing User's Guide for details

2.1.4.3 Database Replay Workload Analyzer

Database Replay Workload Analyzer is a tool that analyzes a captured workload and provides an assessment of how reliably it can be replayed. It highlights any potential problems that might be encountered during replay by outlining the parts that cannot be replayed accurately due to insufficient data, errors during capture, and usage of features that are unsupported by Database Replay.

This feature tells you, at the time of capture, whether the specific workload captured is something that can be relied upon for future testing.

It also helps resolve installation issues at the middle of a release without either recutting the media or deferring the bug fix to a later release.

Currently, when there is a bug in the base installation, you have to wait until the next release before it can be fixed. This feature helps resolve installation issues at the middle of a release without either recutting the media or deferring the bug fix to a later release. The feature also applies mandatory patches for the base product, thereby creating more certified installations out-of-box.

The dedicated network connection, called interconnect, is crucial for the communication in the cluster. Using redundant network connections for load balancing and for failure protection is recommended. While in previous releases, technologies like bonding or trunking had to be used to make use of redundant networks for the interconnect, Oracle Grid Infrastructure for a Cluster and Oracle RAC now provide a native way of using redundant network interfaces in order to ensure optimal communication in the cluster.

Using redundant interconnects optimizes the stability, reliability, and scalability of an Oracle RAC cluster.
