VMS should be executed whenever you have created tapes to be vaulted and are ready to be moved. If VMS is included in the normal CA 1 daily maintenance cycle, it should be executed after the TMSCLEAN utility has finished scratch processing. This prevents expired tapes that are being returned from a vault from appearing on the Scratch and Clean List before they have been physically returned to the library.
We recommend that you back up the TMC using TMSCOPY before executing VMS, so the secondary TMC backup created by TMSCOPY can be vaulted immediately.
When TMSVMEDT is executed without a PARM, a U4000-0006 ABEND is issued if any errors are present in the VPD. TMSVMEDT can be executed with a PARM of TEST to validate the VPD without processing the TMC prior to implementing vault pattern changes.
A condition code check should be used to suppress execution of TMSVMUPD if the TMSVMVLT step ends with a return code greater than 4. The TMC is not updated in this instance, and the movement reports are not produced.
Changes to the VPD can be tested by not executing the TMSVMUPD program, or by using PARM=TEST for the TMSVMUPD execution. Updates to the TMC are suppressed but the Picking, Distribution, and Inventory reports can be generated to show the changes.
