Realtime Tape Processing › Reset Expiration Dates in the TMC in Realtime

Reset Expiration Dates in the TMC in Realtime

CA 1 provides an optional feature that allows you to assign expiration dates in realtime. The Realtime Expiration feature uses the same matching logic as the batch utility TMSEXPDT, with the exception of SELECT=ALL processing. This enables you to apply the expiration dates defined in the Retention Data Set (RDS) to tape files as they are being created. As each tape file being created goes through data set CLOSE processing, CA 1 accesses a memory resident RDS table to perform a lookup on any expiration rules matching the data set name being created. This feature is activated by adding a TMSRDS DD statement to the TMSINIT procedure that points to your installation's RDS. When Realtime Expiration is activated on all systems sharing the TMC, the batch TMSEXPDT utility no longer needs to be run daily.

Note: For information on how to activate TMSINIT see the Utilities and Reports Reference Guide.

Note: SELECT=ALL requires that the TMC be processed for all data sets that match the updated rule. This function may only be performed using TMSEXPDT. TMSEXPDT will continue to be supported for those users not implementing Realtime Expiration Dates in the TMC.
