Prerequisites for the execution of PVSREN

PVSREN renames pubsets or converts pubset notations. For simplicity, this is referred to as “renaming pubsets” below.

The following basic requirements apply to the PVSREN program execution:

• PVSREN is executable only under the TSOS user ID.

• The default catalog ID can only be modified with the system privilege USER-ADMINISTRATION.

• PVSREN uses the SVC 79, so the system parameter SVC79 must be set to 0 or 1.

DRV pubsets

PVSREN also supports the renaming of DRV pubsets. To do this, all disks must be operated in dual mode, since an inconsistent status could otherwise be produced. This requirement is checked by PVSREN.
