1 System Tables

TimesTen stores metadata (information about the contents of your database) in system tables in your database.

Your applications can read the system tables, but it cannot update the system tables. If your application defines a table with the same name as a system table, then your application can read a system table by prefixing the system table name with SYS. For example, SELECT * FROM SYS.TABLES selects rows from the TABLES system table.

Information specific to system tables:

- Locks acquired by users on system tables may prevent others from defining data or executing the SQLPrepare ODBC function or the Connection.prepareStatement JDBC method.

- The last character in name columns is always a space. Therefore, while the column length for name columns is 31, the maximum object name length is 30.

- On 64-bit systems, TimesTen system tables declare certain fields as data type TT_BIGINT. When retrieving these columns with an ODBC program, the application must bind them using SQL_C_BINARY. For information about SQL_C_BINARY, see ODBC documentation.

Note:

Some tables contain columns named SYSnumber. Because these columns contain values used internally by TimesTen, they are not documented in this chapter.

Tables and views reserved for internal or future use

Several system tables and views in TimesTen are reserved for internal or future use. These tables are not described in detail in this chapter:

- SYS.ACCESS$

- SYS.ALL_EXTERNAL_TABLES

- SYS.COLUMN_HISTORY

- SYS.DIR$

- SYS.OBJAUTH$

- SYS.SYN$

- SYS.SYSAUTH$

- SYS.TABLE_HISTORY

- SYS.USER_ASTATUS_MAP

PL/SQL system tables are reserved for internal use. Use the PL/SQL system views instead. PL/SQL system tables in TimesTen are:

- SYS.ARGUMENT$

- SYS.DEPENDENCY$

- SYS.ERROR$

- SYS.IDL_CHAR$

- SYS.IDL_SB4$

- SYS.IDL_UB1$

- SYS.IDL_UB2$

- SYS.NCOMP_DLL$

- SYS.PLSCOPE_IDENTIFIER$

- SYS.PROCEDURE$

- SYS.PROCEDUREINFO$

- SYS.PROCEDUREPLSQL$

- SYS.SETTINGS$

- SYS.SOURCE$

- SYS.USER$

- SYS.WARNING_SETTINGS$

If PL/SQL is enabled in your database, there are tables and views created for the operation of the package UTL_RECOMP:

- SYS.UTL_RECOMP_COMPILED

- SYS.UTL_RECOMP_ERRORS

- SYS.UTL_RECOMP_SORTED

- SYS.UTL_RECOMP_ALL_OBJECTS (PL/SQL view)

- SYS.UTL_RECOMP_INVALID_ALL (PL/SQL view)

- SYS.DBA_INVALID_OBJECTS

- SYS.DISK_AND_FIXED_OBJECTS

- SYS.ERROR_SIZE

- SYS.PARSED_PIECES

- SYS.PARSED_SIZE

- SYS.SOURCE_SIZE

Required privileges to access system tables and views

By default PUBLIC has SELECT privileges on various system tables and views and EXECUTE privileges on various PL/SQL objects. You can see the list of objects by using this query:

SELECT * FROM sys.dba_tab_privs WHERE grantee='PUBLIC';

The ADMIN or SELECT ANY TABLE privilege is required to access other system tables and views.

SYS.ALL_ARGUMENTS

The ALL_ARGUMENTS view lists the arguments of the procedures and functions that are accessible to the current user.

Related views

- SYS.DBA_ARGUMENTS lists the arguments of the procedures and functions that are available in the database. It has the same columns as ALL_ARGUMENTS.

- SYS.USER_ARGUMENTS describes the arguments of the procedures and functions that are owned by the current user. This view does not display the OWNER column.

Columns

Column name

Type

Description

OWNER

VARCHAR2(30) INLINE

Object owner.

OBJECT_NAME

VARCHAR2(30) INLINE

Object name.

PACKAGE_NAME

VARCHAR2(30) INLINE

Package name.

OBJECT_ID

TT_BIGINT NOT NULL

Object number.

OVERLOAD

VARCHAR2(12) INLINE

Indicates the nth overloading ordered by its appearance in the source; otherwise, it is NULL.

SUBPROGRAM_ID

TT_INTEGER

Unique subprogram identifier.

ARGUMENT_NAME

VARCHAR2(30) INLINE

If the argument is a scalar type, then the argument name is the name of the argument. A null argument name denotes a function return. If the function return or argument is a composite type, this view will have one row for each attribute of the composite type. Attributes are recursively expanded if they are composite.
The meanings of ARGUMENT_NAME, POSITION, SEQUENCE, and DATA_LEVEL are interdependent. Together, as a tuple, they represent a node of a flattened tree.

ARGUMENT_NAME can refer to:

- Return type, if ARGUMENT_NAME is NULL and DATA_LEVEL = 0

- The argument that appears in the argument list if ARGUMENT_NAME is NOT NULL and DATA_LEVEL = 0

- Attribute name of the composite type if ARGUMENT_NAME is NOT NULL and DATA_LEVEL > 0

- A collection element type if ARGUMENT_NAME is NULL and DATA_LEVEL > 0

POSITION

TT_INTEGER NOT NULL

If DATA_LEVEL is 0, then this column contains the position of this item in the argument list, or 0 for a function return value.
If DATA_LEVEL is greater than 0, then this column contains the position of this item with respect to its siblings at the same DATA_LEVEL. For a referenced record field, this is the index of the field within the record. For a referenced collection element, this is 1 because collection elements do not have siblings.

SEQUENCE

TT_INTEGER NOT NULL

Defines the sequential order of the argument and its attributes. Argument sequence starts at 1. Return type and its recursively expanded (preorder tree walk) attributes come first, and each argument with its recursively expanded (preorder tree walk) attributes follow.

DATA_LEVEL

TT_INTEGER NOT NULL

Nesting depth of the argument for composite types.

DATA_TYPE

VARCHAR2(30) INLINE

Data type of the argument.

DEFAULTED

VARCHAR2(1) INLINE NOT NULL

Specifies whether or not the argument is defaulted.

DEFAULT_VALUE

VARCHAR2(4194304) NOT INLINE

Reserved for future use.

DEFAULT_LENGTH

TT_INTEGER

Reserved for future use.

IN_OUT

VARCHAR2(9) INLINE NOT NULL

Direction of the argument: (IN, OUT, IN OUT).

DATA_LENGTH

TT_INTEGER

Length of the argument.

DATA_PRECISION

TT_INTEGER

Length in decimal digits (NUMBER) or binary digits (FLOAT).

DATA_SCALE

TT_INTEGER

Digits to the right of the decimal point in a number.

RADIX

TT_INTEGER

Argument radix for a number.

CHARACTER_SET_NAME

VARCHAR2(16) INLINE

Character set name for the argument.

TYPE_OWNER

VARCHAR2(30) INLINE

Owner of the type of the argument.

TYPE_NAME

VARCHAR2(30) INLINE

Name of the type of the argument. If the type is a package local type (declared in a package specification), then the column displays the name of the package.

TYPE_SUBNAME

VARCHAR2(30) INLINE

Relevant for package local types. Displays the name of the type declared in the package identified in the TYPE_NAME column.

TYPE_LINK

VARCHAR2(128) INLINE

Relevant for package local types when the package identified in the TYPE_NAME column is a remote package. This column displays the database link used to refer to the remote package.
TimesTen ignores this value because remote packages are not supported.

PLS_TYPE

VARCHAR2(30) INLINE

For numeric arguments, the name of the PL/SQL type of the argument. NULL, otherwise.

CHAR_LENGTH

NUMBER

Character limit for string data types.

CHAR_USED

VARCHAR2(1) INLINE NOT NULL

Indicates whether the byte limit (B) or character limit (C) is official for the string.

SYS.ALL_COL_PRIVS

This view returns no rows. The column definitions are the same as the column definitions for the SYS.ALL_COL_PRIVS view in the Oracle Database. See Oracle Database Reference.

SYS.MONITOR

The MONITOR table stores information about system performance. It contains a single row with statistics about certain events. For many columns, statistics are gathered starting from the time the database is loaded into memory and statistics are cleared when the database is unloaded from memory. With a ramPolicy of manual or always, the database remains in memory when there are no application connections.

For some columns, statistics are gathered as needed. TimesTen does not gather statistics from the time of the first connection for these columns:

- PERM_ALLOCATED_SIZE

- PERM_IN_USE_SIZE

- TEMP_ALLOCATED_SIZE

- LAST_LOG_FILE

- REPHOLD_LOG_FILE

- REPHOLD_LOG_OFF

- FIRST_LOG_FILE

- CHECKPOINT_BYTES_WRITTEN

For most columns, the MONITOR table is reset whenever there are no connections to the database. TimesTen does not reset the values of the following columns, even when there are no connections to the database:

- PERM_ALLOCATED_SIZE

- PERM_IN_USE_SIZE

- TEMP_ALLOCATED_SIZE

- LAST_LOG_FILE

- REPHOLD_LOG_FILE

- REPHOLD_LOG_OFF

- FIRST_LOG_FILE

TimesTen frequently updates information in the MONITOR table. To prevent these updates from slowing down the system, they are not protected by latches. Hence values in the MONITOR table are not absolutely accurate. They can be used as a reliable indication of activities in the system.

Note:

See the SYS.SYSTEMSTATS table if the desired statistic is not in the SYS.MONITOR table.

2 Replication Tables

TimesTen stores metadata about replication in replication tables in your database.

Your applications can read the replication tables, but it cannot update them. If your application defines a table with the same name as a replication table, then your application can read a replication table by prefixing the replication table name with TTREP. For example, SELECT * FROM TTREP.REPTABLES selects rows from the REPTABLES replication table.

Information specific to replication tables:

- Locks acquired by users on replication tables may prevent others from defining data or executing the SQLPrepare ODBC function or the Connection.prepareStatement JDBC method.

- The last character in name columns is always a space. Therefore, while the column length for name columns is 31, the maximum object name length is 30.

- On 64-bit systems, TimesTen replication tables declare certain fields as data type TT_BIGINT. When retrieving these columns with an ODBC program, the application must bind them using SQL_C_BINARY. For information about SQL_C_BINARY, see ODBC documentation.

Note:

Some tables contain columns named SYSnumber. Because these columns contain values used internally by TimesTen, they are not documented in this chapter.

Replication tables reserved for internal or future use

The TTREP.CLIENTFAILOVER table is reserved for internal or future use.

Required privileges to access replication tables

By default PUBLIC has SELECT privileges on various system and replication tables and EXECUTE privileges on various PL/SQL objects. You can see the list of objects by using this query:

SELECT * FROM sys.dba_tab_privs WHERE grantee='PUBLIC';

The ADMIN or SELECT ANY TABLE privilege is required to access other system and replication tables and views.

TABLECHECK

TT_CHAR(1)

One of the following values:
E (exact) - The table structures on the master and subscriber databases must be identical for replication to occur.

R (relaxed) - Replication can occur between master and subscriber if a relaxed table check has been passed. This means that the number of columns and column data types match for the tables in the master and subscriber databases.

NULL (default) - all other cases

3 System Limits

512

512

Limits on number of open files

Each process connected to a TimesTen database keeps at least one operating-system file descriptor open from the time of the first connection until the process terminates. Additional file descriptors may be opened for each database connection:

- Connections to databases that have logging to disk enabled require an additional two file descriptors for the duration of the connection.

- An additional file descriptor is needed for the duration of database checkpoints issued by the process.

- Additional file descriptors may be opened during transaction commit or rollback operations.

For multithreaded applications that maintain many concurrent TimesTen database connections, the default number of open files permitted to each process by the operating system may be too low.

- On HP-UX, the default is 4096 open files per process and may be raised through the tunable parameter maxfiles or with the ulimit command (limit for csh users). You can also set the per-process limit programmatically with setrlimit.

- On Solaris, the default limit is 256 open files and may be raised for a session with the ulimit command (limit for csh users). You can also set the per-process limit programmatically with setrlimit.

- On AIX, the limit is 2,048 open files, so you are not likely to encounter problems.

- On Linux, the default limit is 1,024 open files, so you are not likely to encounter problems.

- On Windows, the default limit is at least 2,000 open files, so you are not likely to encounter problems.

Most of the open file descriptors are used for reading and writing database recovery log files. If a process fails to open a log file, the database is marked as requiring recovery and all current connections to the database are terminated.

Path names

TimesTen does not support file path names that contain multibyte characters. Make sure that the installation path, database path, transaction log path, and temporary file path do not contain any multibyte characters.
