The PURGE command accepts the optional operand OLDVOLNO and will check the data sets that had been migrated to volumes that match the volume specified to determine if they are still cataloged to it, and will purge the MIGRECAT records for any data sets that are no longer cataloged to that volume and that the expiration date has expired. The optional operands NOEXP and NOCAT instruct the utility to ignore the expiration date and catalog status in the eligibility determination. It also accepts the SIMULATE operand and will perform a test run if it is specified.
The PURGE command syntax is:
PURGE SIMULATE,VOLUMES=,DSNAMES=,LIST=,SCRATCH=,DELPROF=,NOVALIDATE,FORCE
The volume serial, or a pattern, of the original volume that should be checked for Purge eligibility.
The presence of this keyword causes messages to be produced as if purging was taking place when, in fact, no MIGRECAT records will be purged.
The presence of this keyword causes the expiration date that was stored in the MIGRECAT record to be treated as if it has expired. This is the only method to purge records with a permanent retention date.
The presence of this keyword eliminates the check of the data set's catalog status. It will cause the data set to be treated as if it were no longer cataloged to the original output volume.
