Using the Tape Retention System (TRS) › Running the Tape Retention System

Running the Tape Retention System

You will normally run the Tape Retention System as a daily production job. It will use the information in the Volume Master File and Retention Master File to determine whether to:

• Release tape volumes to the scratch pool if their retention period has expired and no other locations have been specified.
• Move them from the data center to another location.
• Move them from one location to another location.
• Move them back to the data center for scratching when all retention periods have expired and no other locations have been specified.

It will then produce the following reports:

• A movement report showing which volumes must be moved from location to location.
• A scratch report showing which volumes are ready for release to the scratch pool.
• An optional Volumes By Retention Method report in data set name sequence showing how individual volumes are being retained at their current location, and where they are destined to move when their current retention criteria are satisfied.
• An error/exception report showing retention errors and exceptions, as well as conflicts between controlling data sets on multi-data set volumes.

Important! If the SCRATCH=ALL option is coded in TLMSIPO, tapes do not go scratch until all data sets expire by type 3 retention, regardless of the retention type in effect before the CDS. This option may prevent proper vault movement or a shortage of available scratch tapes.

SCRATCH=ALL is not recommended. Retention type A, B, or C should be assigned as needed.
