CA 1 Scratch Synchronization Job

The Scratch Synchronization Job generates a CA 1 scratch report to determine which Virtual Volumes are in scratch status. Then the job updates those Virtual Volume entries in the Global VCAT that require a status change.

Sample JCL for the CA 1 scratch synchronization job can be found in HLQ.CCUUJCL(CA1). Follow the JCL comments to customize the job with the appropriate CA 1 options data set. You can also customize with the prefix character or characters of the defined Virtual Volume VOLSER ranges. If you use the CA 1 ROBSCR option, you still customize the Scratch Synchronization Job and execute it once a week or month to ensure that all scratched Virtual Volumes are kept in-sync.

TMSCLEAN only notifies CA Vtape when a Virtual Volume is scratched. If that notification fails, TMSCLEAN does not issue another notification. The Scratch Synchronization Job requests a CA 1 scratch report so it always checks all Virtual Volumes in scratch status to ensure that they are in-sync.
