DBG72032E DB5P 04:07:03 ERROR INVOKING IMOD IDB2MEXC ON ISERV ISRV (RC=0016-00000016) FOR THE FOLLOWING EXCEPTION:
DBG11016E DB5P 04:07:03 GSS ERROR: GSS Address Space is not active
Release : 20.0
Component : CA SYSVIEW Performance Management Option for DB2 for z/OS
These messages occurred due to the IDB2 DC being started before the GSS address space was initialized.
The DBG11016E DB5P 04:07:03 GSS ERROR: GSS Address Space is not active message occurred because the IDB2 DC task started before the GSS address was started. Once the GSS task was fully initialized, IDB2 could successfully communicate with the GSS address space.
