The Tape Retention System (TRS) runs in batch mode.
TRS accesses the VMF in read-only mode using its own private copy of TLMSVMRW.
The Retention Master File (RMF) is accessed to determine any special retention handling to be applied on a DSN basis.
Various printed reports are prepared.
VMF updates (for example, scratches) are performed by building CA TLMS transaction, type 5, and writing it to a transaction file. TLMSTRAN reads this file after a successful TRS run and issues the TLMSQMGR SVC.
TLMSQMGR is activated through the SVC.
The TLMSQMGR module gains control, receives each transaction, and cross-memory posts TLMSMAIN.
TLMSMAIN is activated by the cross-memory post.
TLMSMAIN responds to the post by calling TLMSMSGQ.
TLMSMSGQ receives a copy of the transaction by calling the TLMSQMGR SVC and then calls TLMSUPDT.
TLMSUPDT accesses the Volume Master File specified in the CTS procedure through routines in its copy of TLMSVMRW.
The VMF is accessed by volume serial number (VSN).
The retrieved VMF record is updated.
(Optional) A copy of the transaction is written to the Alternate Log file if the RECOVRY system option is set to ALTLOG.
TLMSMSGQ is notified that the update is completed.
