• SYSVIEW Performance Management Option for DB2 for z/OS

Issue/Introduction

After changes to GSS in support of Sysview Performance Management Option for Db2 for z/OS (IDB2) encountered several DBG11015E error messages:
    
DBG11015E 16:00:16 IMOD ERROR RETURN CODE 16 REASON 22
DBG11016I 16:00:16 GSS ERROR: PC table entry not found
DBG11015E 16:02:36 IMOD ERROR RETURN CODE 16 REASON 22
DBG11016I 16:02:36 GSS ERROR: PC table entry not found
DBG11015E 16:09:50 IMOD ERROR RETURN CODE 16 REASON 22
DBG11016I 16:09:50 GSS ERROR: PC table entry not found
 
Checked the MSSUB parameter to identify the GSS ssid in the IDB2 data collector and GSS started task but all the names were correct.

Resolution

The GSS started task was executed by program SRVSYS, the SRVSYS program is used to bring up a secondary GSS address space.
There must also be a primary GSS address space. If this GSS started task is the only GSS address space running on the LPAR,
you must change the JCL and execute PGM=GSSMAIN instead of SRVSYS.
