Oracle Database Discussions

I think I've screwed up... I was applying the latest patches to my 9.2 Oracle DB on numerous servers we have. The 1st server patched with no trouble. As a test, I try to get into applications, and OEM to see if I can get to all the tables, etc. I also try to run an export job and then see if I can import into another test DB. After that success, I attempted another server on another network. It all worked as the previous server... however my export didn't work. I decided to roll back the patch and start again... I used Opatch and did a rollback of the patch... it worked successfully... however, now when I try to do the lsinventory, I get the message, No interim patch... I'm at a loss as to what to do. Any advice would be greatly appreciated. Thanx.
