Issue/Introduction

After upgrading Sysview for DB2 the following error messages occur:
DBG72032E DSN 08:20:19 ERROR INVOKING IMOD $DBGL_ILOGMSG ON ISERV ISRV (RC=-225-00000004) FOR THE FOLLOWING EXCEPTION:
DBG11016I DSN 08:20:19 GSS ERROR: IMOD was not found.  Also, the GSS task output showed: GRX0043I Execution Error....  

Environment

Release : 19.0, 20.0

Component : CA Sysview for DB2 Performance Monitor  (IDB2)

Cause

The cause of the DBG72032E error was due to the MSSUB parameter being specified in IDB2's sysparms not correctly referencing the GSS' SSNAME value. 
Also, the GRX0043I execution error message was caused by an old IMOD dataset being referenced.
 

Resolution

The DBG72032E error was corrected by changing the default MSSUB parameter value (ISRV) in IDB2's sysparms to the GSS task's SSNAME value of GSS1.
The GRX043I Execution error message in the GSS task joblog was corrected by reloading the IDB2 IMOD dataset with current IMODs.
