Small data set packing data set security

Because data sets that migrate to small data set packing (SDSP) data sets are treated as records in the SDSP data set, they must be protected by applying security to the SDSP data set. The security applied to the SDSP data set prevents non-DFSMShsm access to the data in the data sets treated as records.

To maintain data set security on your system’s small data set packing data sets, RACF-protect them with a discrete or generic profile. Erase-on-scratch should be specified in the discrete or generic profile if erase-on-scratch is specified for DFSMShsm data sets not in SDSP data sets.

If data sets on volumes managed by DFSMShsm are protected by a password and you specified SETSYS SMALLDATASETPACKING, protect the SDSP data sets on ML1 volumes with a discrete or generic profile to extend the protection of the data sets contained in the SDSP data sets. DFSMShsm can still access the data sets in a protected SDSP data set without being given access authority to the SDSP data set.
