Deleting Expired Backed-Up Reports

After the retention period for backed up reports has expired, delete the reports and release the tape (cartridge) on which they reside. Control-D utility CTDCLHST (clear history) deletes expired backed up reports.

Utility CTDCLHST performs the following tasks:

• Deletes entries of expired reports from the History User Report file.
• Produces a list of all tape (cartridge) volume serial numbers that are no longer needed. Under HSM, an HSM DELETE command is performed for each of the deleted reports.

There is no need to specify parameters for this utility. Just submit the example from the Control-D JCL library.

It is recommended that you run this utility once a day, or at least once a week.
