I got the same thing. SR indicated to upgrade agents to 10.2.0.4 and to do that OEM should be upgraded as well to 10.2.0.4. patches 7031906, and 3731593. havn't looked into them yet. You can try a work around in the mean time. Backup then edit the file agent ORACLE_HOME/sysman/admin/default_collection/instance.xmlp and change the line: <Metric NAME="health_check" TYPE="TABLE"> to <Metric NAME="health_check" TYPE="TABLE" DISABLED="TRUE"> Joel Patterson Database Administrator joel.patterson@xxxxxxxxxxx x72546 904 727-2546 ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Arnold, Sandra Sent: Monday, July 21, 2008 3:22 PM To: oracle-l@xxxxxxxxxxxxx Subject: OEM Agent Issues after Upgrade 10.2.0.4 I am having some major issues with the OEM Agent after I upgraded it to 10.2.0.4 on my production server. The OS is Solaris 64-bit version 5.10. I had this same issue on my Sandbox which is 5.10 and my DEVTEST server which is 5.9. I applied patch 6276119 which fixed the problem on those two servers. However on this server that is not the case. I don't know whether all the errors are caused by one problem or whether I have multiple issues. Here are some of the errors I am getting and the files they are in. I have removed any port #, server name, ip address, or sid name since that informationis considered to be sensitive information. I think I have provided all the errors. One thing I haven't done is to delete everything in the OMS server for the production server and rediscover it. Any help that I can get would be greatly appreciated. I know Oracle support is going to want log files, configuration files, etc. Unfortunately because of security policies here I can not send those files.
