Issue/Introduction

How do I get rid of Disk temporary Catalog Entries?

Environment

Release: Disk™ Backup and Restore

Resolution

Disk™ Backup and Restore needs a volser before OPEN so it uses DMSTMP until a real volume is allocated. If the Disk job abends before a volume is assigned, then a catalog entry of DMSTMP is left behind. If Disk™ Backup and Restore fills a tape and then requests a new tape but then discovers there is nothing left to archive, then a DMSTMP catalog entry can remain. Disk does not have any knowledge of these catalog entries so there is nothing that needs to be cleaned up in Disk™ Backup and Restore.
 
To get rid of the DMSTMP catalog entries, they can simply be uncatalog / deleted.  There is no possibility of any data loss. No Disk utilities are available to automatically uncatalog the entries.

Additional Information

Some references to DMSTMP can be found in this manual:

Refer to Disk™ Backup and Restore tech docs for the description of Sysparm ARCTNAME.

If your security system protects tape volumes and you want to specify options C or G for sysparm ARCTNAME,
you must also ensure that all users running backup or archive jobs have access to tape volume DMSTMP.
