Two fields in the PSS option block directly affect PSS recovery: SYSTEM NAME and PREFIX NAME. SYSTEM NAME is used as part of the enqueue name for the ADROUT library. PREFIX NAME is used to enqueue specific output. If your site has multiple CA Ideal CICS regions, PSS recovery might not work properly if these fields are not correctly set, even if each region has its own ADRPNL and ADROUT library.
When PSS recovery is initiated, an exclusive enqueue is issued against the ADROUT library. The first three characters of the enqueue name are built from the value specified in the SYSTEM NAME field of the PSS Options Block. After all eligible outputs are deleted, PSS recovery is terminated and the exclusive enqueue is changed to a shared enqueue.
When the next CA Ideal CICS region is started, PSS recovery once again uses the three characters from the SYSTEM NAME field in the PSS options block and tries to issue an exclusive enqueue. If the PSS system name specified for this CICS region is the same as the system name for the first CICS region, the exclusive enqueue request fails because the first CA Ideal CICS region is still holding a shared enqueue against the ADROUT library. Therefore, make sure that the system name and prefix name are unique for each library.
