Data set retention date

DFSMSrmm uses the earliest date for a data set as the retention date for the data set. DFSMSrmm sets the retention date for the data set by using the current vital record subchain as follows.

CATRETPD, when the WHILECATALOG retention type retains CATRETPD, but is not yet cataloged.
The earliest actual date. The actual date is the day on which the current matching vital record specification no longer retains the data set. If a data set is permanently retained, the retention date is set to PERMANENT and not 1999/365. DFSMSrmm sets the retention date based on one of these dates.
1. The date a data set is created or last referenced when the DAYS or LASTREFERENCEDAYS retention type is specified.
2. The date the name vital record specification starts to retain the data set when the EXTRADAYS retention type is specified.
3. The volume expiration date, if the UNTILEXPIRED retention type, is specified.
4. The vital record specification deletion date if a DELETEDATE other than DELETEDATE(1999/365) is specified.
WHILECATLG, if WHILECATALOG is specified.
'CYCL/ccccc', if BYDAYSCYCLE or CYCLES is specified.
PERMANENT, which specifies that the data set is retained forever.

Note: DFSMSrmm uses the retention date that is the earliest when a data set matches both a primary and a secondary vital record specification, is still eligible for retention, and the primary vital record specification includes the UNTILEXPIRED retention type.
