I am just starting to work with Oracle.. please bear with me.

I installed for Windows 2003 server, after which everything worked fine. OEM started fine, and I was able to talk to everything.

Then I went to apply the patchset (the newest that I could find), and now OEM does not connect to the database instance. The Agent to connection Instance is down as well. The listener however, is up.

I followed the instructions in the release notes to stop all the services and databases properly, and I've looked at Metalink articles for an hour trying to troubleshoot this apparently simple issue.

I did change the SYS and SYSTEM passwords upon the install, but other than that, it was a perfectly vanilla install!! I applied the patchset immediately after and it broke.

Can anyone help me?

Thanks in advance!
