OA50356: NEW FUNCTION: AUTOMATIC DELETION OF CIM REPOSITORY BACKUPS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• Whenever an upgrade to the CIM repository is made via PTF or
  upgrade, a backup of the current repository is made to the
  /var/wbem/ directory.  These are not cleaned up and over time
  there can be numerous copies of old repositories, with a small
  chance of these being needed.  This can cause excessive growth
  of the CIM file system for unnecessary data.  Users have to
  manually remove directories to free up space.  Having aggrgrow
  on for all data sets is not a long term option as the file could
   grow excessively, again due to backups that are not needed. We
  should implement an automatic deletion of repository backups
  either based on version (like a z/OS GDG) or date . This will
  clean up old directories.
  

Local fix

• Customers have to manually remove directories to free up space

  * RECOMMENDATION:                                              *
  ****************************************************************
  Introduce a new CIM server configuration maxRepositoryBackups
  to configure how many repository backups the customer want to
  have. When there is a success repository upgrade, CIM will scan
  the repository directory for the repository backups, just keep
  the number of maxRepositoryBackups latest repository backups.
  The others will be deleted.
