• 6.1 Local Oracle Database Client Connections

  6.2 Performance Issues with Generic Connectivity

  There is a performance issue with Generic Connectivity (hsodbc). On the first query of a new connection, there could be significant delay up to several minutes. All subsequent SQL issued through the same dblink session will proceed without delay.

  Check Oracle bug 4549924 for patch availability.

  6.3 Cluster Verification Utility

  Third Party Clusterware

  If your deployment environment does not use HACMP, ignore the HACMP version and patches errors reported by Cluster Verification Utility (CVU). On AIX 5L version 5.2, the expected patch for HACMP v5.2 is IY60759. On AIX 5L version 5.3, the expected patches for HACMP v5.2 are IY60759, IY61034, IY61770, and IY62191.

  If your deployment environment does not use GPFS, ignore the GPFS version and patches errors reported by Cluster Verification Utility (CVU). On AIX 5L version 5.2 and version 5.3, the expected patches for GPFS 2.3.0.3 are IY63969, IY69911, and IY70276.

  Check Kernel Parameter Settings

  CVU does not check kernel parameter settings.

  This issue is tracked with Oracle bug 4565046.

  Missing Patch Error Message

  When CVU finds a missing patch, it reports a xxxx patch is unknown error. This should be read as xxxx patch is missing.

  This issue is tracked with Oracle bug 4566437.

  Verify GPFS is Installed

  Use the following commands to check for GPFS:

  cluvfy stage -pre cfs -n node_list -s storageID_list  [-verbose]
  cluvfy stage -post cfs -n node_list  -f file_system   [-verbose]
  

  This issue is tracked with Oracle bug 456039.

  6.4 Oracle XML Developer's Kit Compiler Support

  6.5 Importing a User Certificate Into Oracle Wallet Using Oracle Wallet Manager

  Oracle Wallet Manager will fail to recognize the user certificate as valid if you capture the user certificate contents from the Oracle Certificate Authority site and save this as a flat file. This is because when saving as a flat file, all the lines of the user certificate are run together with no line breaks.

  Workaround: Edit the user certificate. Insert a new line after -----BEGIN CERTIFICATE----- and a new line before -----END CERTIFICATE-----.

  6.6 Removing Metrics for Wait Classes Removes Them Permanently

  Do not remove the key values for the wait class metrics. Doing so removes them permanently and currently there is no easy way to recover them.

  This issue is tracked with Oracle bug 4602952.

  6.7 Hitachi HDLM for Storage

  If you use Hitachi HDLM (dmlf devices) for storage, then automatic storage instances do not automatically identify the physical disk. Instead, the instances identify only the logical volume manager (LVM). This is because the physical disks can only be opened by programs running as root.

  Physical disks have path names similar to the following:

  • /dev/rdlmfdrv8

  • /dev/rdlmfdrv9

  7 Documentation Corrections and Additions

  This section lists the following corrections to the installation guides for AIX 5L Based Systems (64-Bit):

  • In Oracle Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide, Chapter 2, "Preinstallation," in the section "Oracle Clusterware Home Directory," it incorrectly lists the path /u01/app/oracle/product/crs as a possible Oracle Clusterware home (or CRS home) path. This is incorrect. A default Oracle base path is /u01/app/oracle, and the Oracle Clusterware home must never be a subdirectory of the Oracle base directory.

    A possible CRS home directory is in a path outside of the Oracle base directory. for example, if the Oracle base directory is u01/app/oracle, then the CRS home can be an option similar to one of the following:

    u01/crs/
    /u01/crs/oracle/product/10/crs
    /crs/home
    

    This issue is tracked with Oracle bug 5843155.

  • The following text of the section 2.6.1, "IP Address Requirements," in Chapter 2, "Pre-Installation Tasks," of Oracle Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide states that the virtual IP address (VIP) should respond to a ping command:

    During installation, Oracle Universal Installer uses the ping command to ensure that the VIP is reachable.

    The preceding statement is incorrect. Before installation, the VIP address should be configured in DHCP or /etc/hosts, or both, but it must not be assigned to a server that can respond to a ping command.

    This issue is tracked with Oracle bug 6017001.

  • Appendix H, "Database Limits" of Oracle Database Administrator's Reference for UNIX-Based Operating Systems states the incorrect maximum value (63) for the MAXINSTANCES variable. The correct maximum limit for the variable is 1055.

  8 Documentation Accessibility

  Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

  Accessibility of Code Examples in Documentation

  Screen readers may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, some screen readers may not always read a line of text that consists solely of a bracket or brace.

  Accessibility of Links to External Web Sites in Documentation

  This documentation may contain links to Web sites of other companies or organizations that Oracle does not own or control. Oracle neither evaluates nor makes any representations regarding the accessibility of these Web sites.
