I just wanted to pass this on in case it is helpful to anyone out there running 10.2 on Oracle.

We upgraded a Windows Zone from 10.1.3 to 10.2 that was running using the Oracle DB. The system update installed on the server without any problems but would fail on the agents.

We used the services-messages.log file to determine that it was unable to pass data to the correct indexes. The bad indexes were renamed or deleted and the problem was fixed.

Hope this helps someone.
