PM45324: COORDINATED DB2 AND IMS DISASTER RECOVERY AND UCB ONLINE CHECK ENHANCEMENT

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• Provide the following enhancements
  1.Coordinated DB2 and IMS DR (using volume level recovery and
  recovery to end of last good log).  This will focus only on
  system restore and not application restore at this time.
  
  2.An enhancement to prevent users from accidentally overwriting
  target volume serials when performing Flash or Snap profiles
  where UCB numbers are used as targets.  With this type of
  profile, if the UCBs are online during a backup, RE will now
  issue an error message:
  
  ARYS457E - Target unit C0B0 is online with volser EA1102. It
  must be offline for this type of backup.
  ARYS118E - Check target UCBs and vary them offline before
  submitting the backup.
  
  Before this check, RE would automatically vary these UCBs
  offline and their contents would be replaced by the DB2 source
  volumes (including the volume serial).  This could cause
  potential issues on the next z/OS IPL with duplicate volume
  messages.  This check allows users to decide if this is indeed
  the desired result. If they wish to proceed,
  they need to vary the online target UCBs offline, then run the
  backup.
