DSNB307I   csect-name GROUP BUFFER POOL gbpname WAS SUCCESSFULLY ALLOCATED BUT THE EXCLUSION LIST WAS NOT HONORED

Explanation

DB2® successfully connected to the group buffer pool and allocated the group buffer pool in a coupling facility. However, the group buffer pool was allocated in a coupling facility containing a structure in the exclusion list.

System programmer response

If you require that the exclusion list be honored, you must ensure that there is sufficient space in the coupling facilities that are not in the exclusion list. IFCID 0250 provides information about which facilities were attempted.
