Applying an Update Prerequisite Tasks

Before applying the update to move to Oracle Enterprise Performance Management System Release 11.2.15:

  1. Disable the anti-virus software before you install and configure Release 11.2.15. Ensure that you have the anti-virus software disabled for the entire duration of the install and configuration process. Anti-virus software can be re-enabled when the installation is complete.
  2. Stop all the services. For more information, see Starting and Stopping EPM System Products.
  3. Back up the following folders:
    • EPM Oracle Home. The default EPM Oracle home location is MIDDLEWARE_HOME/EPMSystem11R1.
    • EPM Oracle Instance. The default location for the EPM Oracle Instance is MIDDLEWARE_HOME/user_projects/epmsystem1.

    You can delete these folders after you apply the update and validate the installation.

  4. Back up the keystores (only for SSL environments) from:
    • MIDDLEWARE_HOME\jdk\jre\lib\security\cacerts
    • MIDDLEWARE_HOME\EPMSystem11R1\common\JRE\Sun\1.8.0\lib\security\cacerts

    Note:

    Ensure that you restore the backed up keystores (cacerts) after the installation and configuration process.

  5. If the files (for example, "Calc Scripts", "Rule Files") in your 11.2.x Essbase instance have names that contain non-English characters , they might not be converted to Essbase 21c as part of the upgrade to EPM 11.2.15. Ensure that you manually migrate those files.

  6. Ensure that there is at least three times as much free space as the total size of the Essbase cube in your temp directory when upgrading from Release 11.1.2.x to Release 11.2.15. For example, if the data size of the Essbase cube is, for example, 10 GB, then there must be 3 * 10 (30 GB) of space available in your temp directory.

    This space will be cleaned up after the upgrade process and is only used for temporary purposes.

  7. For EPM products using Java API (JAPI) - Ensure that you take a backup of the file EPM_ORACLE_HOME\common\EssbaseJavaAPI\11.1.2.0\bin\essbase.properties and copy it to EPM_ORACLE_HOME\common\EssbaseJavaAPI-21C\11.1.2.0\bin\essbase.properties after the upgrade to Release EPM 11.2.15.
