BACKUP Maintaining the DSN Catalog (TSIDUTL)
6-6 BIM-EPIC Installation and System Guide
BACKUP
BACKUP performs a logical record backup of the DSN Catalog. DSN Catalog access is
denied to other jobs while BACKUP is running. BACKUP tests record pointers to ensure
catalog integrity. If any errors are detected, a diagnostic report is produced.
After BACKUP is run, we recommend backing up and clearing the Recorder File. For
increased security, perform the two backups on separate tapes.
Catalogs backed up with the BACKUP function can only be restored with RESTORE.
RESTORE can be used to create a DSN Catalog with a different size and location.
See RESTORE
BACKUP
None
No label information for the DSN Catalog is needed. BACKUP accesses the currently active
catalog (the one that was opened when BIM-EPIC was started).
The backup dataset can be a controlled dataset, but it must be available even when BIM-EPIC
is not running, so be sure to manually record the volume serial number on which the backup is
written. A TLBL or DD statement for BACKUP is required.
The backup dataset must not be reblocked. A reblocked backup dataset cannot be used to
restore the DSN Catalog.
This example produces a backup on tape.
