Tasks for maintaining the control data sets

The tasks for controlling automatic backup of the control data sets require adding DFSMShsm commands to the ARCCMDxx member. The tasks for retrieving the backup control data sets require the invocation of CDS recovery utilities. The following tasks maintain the control data sets:
  • Code SETSYS CDSVERSIONBACKUP to tell DFSMShsm how to back up the data sets automatically.
  • Manually back up the control data sets using the BACKVOL CDS command, when automatic backup is not used.
  • Recover the control data sets by using the enhanced CDS recovery utilities.
  • Issue a DFSMShsm command to determine if the control data sets match the contents of the computing system catalogs and the VTOCs of the DASD volumes.
  • Issue commands to repair errors in the control data sets.
