Understanding CICS VR AIX processing for BWO backups

CICS® VR performs additional AIX® processing for a DFSMShsm logical backup that was made using the BWO facility.

A VSAM sphere backup made while the sphere was being updated by CICS using the BWO facility can be in a "fuzzy" status. A "fuzzy" status indicates that the backed up base cluster might include some updates that are not reflected in a backed up AIX. For example, the base cluster might have been updated before the backup was made, but the AIX might not have been changed to reflect this same update until after the backup completed.

When a BWO backup in "fuzzy" status is selected through the CICS VR panel interface, CICS VR removes all AIXs that are reusable and part of the upgrade set prior to forward recovery processing. The AIXs are then rebuilt after successful completion of forward recovery processing.
Note: CICS VR does not rebuild AIXs when a new name has been specified for the restoration and forward recovery of a VSAM sphere.
