Always-call support for migrated data sets and backup copies

The DFSMShsm option NORACFIND in the SETSYS command requires that you protect DASD migration copies and backups with generic profiles in an always-call environment. DFSMShsm does not set the RACF® indicator on for these data sets.

The SETSYS command has MIGRATEPREFIX and BACKUPPREFIX parameters that allow all migration data sets and backup data sets to have a high-level qualifier selected by the installation.

When the SETSYS MIGRATEPREFIX and BACKUPPREFIX parameters are used, you can define one or two generic profiles to protect all the migrated and backed up data sets. These profiles should have an empty (or nearly empty) access list and a UACC value of NONE. The following example shows how RACF definitions can be set up to protect the migrated and backed up data sets.

SETROPTS GENERIC (*)
   ADDGROUP (prefix)
   ADDGROUP (bprefix)
   ADDSD 'prefix.*' UACC(NONE)
   ADDSD 'bprefix.*' UACC(NONE)

For an explanation of prefix and bprefix, see Specifying the first qualifier for names of migrated data sets and Specifying the first qualifier for names of backup versions.

Set the system-wide RACF options to include generic profiles.
If you choose MIGPREF as the migration prefix and BAKPREF as the backup prefix, generic profiles MIGPREF.* and BAKPREF.* protect all the DFSMShsm migrated and backed up data sets.
The ADDSD command builds a generic profile for MIGPREF and another for BAKPREF.
