For some reason the PCSSID is not being passed when selecting a specific DB2 subsystem when selecting IS form the panel during the upgrade to R20. The PCSSID is setup in the *SYSP member which is concatenated to the parms in the *IDB2 task.
When the sysview clist was being called there were we two versions on the insight clist. One for the old release and one for the new release. The PCSSID for both were pointing to the same structure old release structure. Updating the CLIST to point to the correct PCSSID.
