After upgrading a test DB2 subsystem to DB2 11 CM, why am I not able to get into Sysview Performance Monitor for DB2 for z/OS (IDB2) from the CA DB2 Tools' Main
Menu? Selecting 'IS' for Sysview Performance Monitor for DB2 for z/OS (IDB2) from the CA DB2 Tools' main menu I receive the message:
CA SYSVIEW FOR DB2 USER SESSION FAILED WITH RC=12 ENSURE THE POST INSTALL STEPS HAVE BEEN COMPLETED BEFORE INVOKING THE USER INTERFACE.
Maintenance had been applied to the CA DB2 Tools, and the propagation of the SMP/E Target libraries to the CA DB2 Tools' Runtime libraries caused the previously
modified Insight clist (from the Post Install process) to be overlaid with a 'vanilla' unedited version, thus the cause of the error message.
A backup copy of the edited Insight clist was copied into the CA DB2 Tools' runtime clist (CDBACLS0) library. This corrected the error condition.
