Real-time Tape Processing › Reset Expiration Dates in the TMC in Real Time

Reset Expiration Dates in the TMC in Real Time

CA 1 provides an optional feature that allows you to assign expiration dates in real time. The Real-time Expiration feature uses the same matching logic as the batch utility TMSEXPDT, with the exception of SELECT=ALL processing. You can apply the expiration dates that are defined in the Retention Data Set (RDS) to tape files as they are being created. 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 RDS. When Real-time Expiration is activated on all systems sharing the TMC, you no longer need to run the batch TMSEXPDT utility daily.

Note: For more information about activating 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. You can perform this function using TMSEXPDT only. TMSEXPDT is supported for users who do not implement Real-time Expiration Dates in the TMC.
