P.S. I was referring bug 8821030, OMS Upload to Repository Fails with .... TASK_COUNT ... ID 1063856.1 Anyway, this scenario is that the agent needs another field, whereas yours is that it won't have it. Some of the Agents which are monitoring 11.1.0.x version of Databases have been upgraded to the 10.2.0.5 version. Cause Issue has been investigated in Bug 8821030: JAVA.SQL.SQLEXCEPTION: ORA-904: "TASK_COUNT": INVALID IDENTIFIER This issue occurs when Oracle Management Service version 10.2.0.4 or lower collects information from 10.2.0.5 agent(s) version. The Oracle Management Service prior to 10.2.0.4 version does not have a required column in a specific repository table, which a 10.2.0.5 agent is trying to insert to. The xml files which fail the upload are related to the latest_hdm_metric_helper metric of the 11g Database.

In your situation, if you upgrade OMS, then the 10.2.0.4 agent will send one less field than exists in that same table. I cannot tell you if it will fail or if that will generate [error] messages. Just passing the info along for your consideration. This is all buried in an SR somewhere in the past, so I don't have the specifics.

I'm reading docs and I still have some opened questions: - remote systems using 10.2.0.4 em agent will continue to work? - weblogic server have to be installed after upgrade? Which configuration requires? From metalink matrix I've found that DB may continue to be 10gR2 and need not to be upgraded to 11g Any others experience to share?
