Data Set Retention Rules

SMS maximum retention rules can be applied to data sets. If parameters SMS and SR are both specified to YES in the TMOOPTxx member of hlq.CTAPOPTN, and a valid SMS Management Class is assigned to the data set, the expiration date is checked with the SMS Management Class definition.

If the TMC expiration date exceeds the SMS Management Class rule, the expiration date is set to the current date plus one day. The X'80' bit in FLAG4 is set to indicate that the volume was expired by SMS. A warning message appears on TMS Report-85.

This method expires any volume that exceeds the SMS Management Class maximum retention value. The volumes include data sets with CA 1 keyword expiration dates.
