Upgrading and extending existing pubsets

Indicating whether large objects are permitted in a pubset

Existing pubsets can be upgraded to large pubsets with and without large files using the SET-PUBSET-ATTRIBUTES command (see SET-PUBSET-ATTRIBUTES / SHOW-PUBSET-ATTRIBUTES).

Changes to the LARGE_OBJECTS attributes only take effect the next time the pubset is initialized (using the IMPORT-PUBSET command).

Adding large volumes to a pubset

Individual volumes can be added to an SF pubset or to a volume set in an SM pubset using the MODIFY-PUBSET-PROCESSING command; new volume sets can be added to an
SM pubset in the same way.

If the volumes to be added are large volumes or if the (empty) volume sets that are to be added contain large volumes, the pubset being extended must be a LARGE_OBJECTS pubset. If this is not the case, the attempt to extend the pubset will be rejected with message DMS1383 (with insert '06'):

DMS1383    VOLUME INCONSISTENT. ERROR TYPE '(&00)'. COMMAND REJECTED
          '06': A volume is larger than 32 GB, but the pubset doesn't have
                the attribute for large volumes.

The addition of a large volume in the context of IMPORT processing will only be successful if the pubset to be extended is a LARGE_OBJECTS pubset. If this is not the case, the attempt to extend the pubset will be aborted with message DMS037E (with insert &00='04'):

DMS037E    FORMAT OF VOLUME '(&02)' INCONSISTENT WITH PUBSET/VOLUMESET
          '(&00)'. IMPORT PUBSET TASK ABORTED WITH ERRORCODE '(&01)'
          '04': A volume is larger than 32 GB, but the pubset doesn't have
                the attribute for large volumes.
