Maintaining the DSN Catalog (TSIDUTL) RESTORE
Chapter. 6 Additional BIM-EPIC Utilities 6-13
RESTORE
RESTORE restores and reorganizes the DSN Catalog from a backup dataset created using
TSIDUTL BACKUP. RESTORE can be used to create a DSN Catalog with a different size
and location. See 4-8 for complete restore procedures in an emergency situation.
See BACKUP.
When running a RESTORE, no other job or CPU should access the DSN Catalog. Do not
attempt to back up and restore the DSN Catalog in the same TSIDUTL execution.

SORTWK1 is required. SORTWK1 must be specified as either Start Track 1 or uncontrolled.
SORTWK1 must be large enough to contain a 50-byte record for every dataset name and
volume serial number in the DSN Catalog.
BACKUP is required. Its tape volume serial number or disk location must be identified.
WORK is required. WORK must be specified as either Start Track 1 or uncontrolled.
WORK must be large enough to contain an 50-byte record for each subdataset (NSU) in the
DSN Catalog. For tape-only systems, if a VSAM/SAM dataset is used for the WORK dataset,
specify RECSIZE=50.
