RELATED IDEAS

Introduce RMM defaults table (DEFTABLE) operand that can request DFSMSrmm record the data set details only for the first file on a tape volume.

The EDG_EXIT100 parameter list has a PL100_CAN_IGNORE_FILE2_TON value that can be used to request that DFSMSrmm record the data set details only for the first file on a tape volume. This is useful to help minimize the overall size of the RMM Control Data Set (CDS) in situations where only the first file on a tape volume needs to be tracked by DFSMSrmm. For example, there are software products that manage the data sets they write to tapes and only the first data set needs to be recorded by DFSMSrmm. Currently, this is only possible to do with a customized EDGUX100 installation exit. However, if there was an equivalent DEFAULT TABLE operand, then users could implement this functionality without having to maintain their EDGUX100 exit code.
