TEPS can be successfully configured to connect and create DB2 TEPS database, but TEPS fails to start

The problem: The TEPS can be successfully configured to connect and create the DB2® TEPS database, but TEPS fails to start

The solution: Resolve the issue with the TEPS and DB2 v9.1 upgrade by completing the following steps:

Udpate db2check.sh to point to v9.1.
Update kcqenv to point to v9.1
Udate cq.ini to point to v9.1 and lib64.
Remove /opt/IBM/ITM/bin/migrate-env.sh and /opt/IBM/ITM/aix533/cq/sqllib/migrate.log migrate files.
Run the './itmcmd config -A cq' command.
Start agent by running the './itmcmd agent start cq' command.

After completing these steps, the TABLES build and the TEPS function correctly.
