Reinstalling Oracle10g Grid Control

I recently went on a very nice vacation to Curacao. Before I went on vacation the Oracle 10g Grid Control (10.2.0.2) I had installed on my Laptop for monitoring my home office systems was working. I took my laptop with me to allow offload of pictures from my cameras and to track email while I was away. When I returned home and hooked my laptop back up to my home network Grid Control wouldn’t start and of course even with the excellent (not!) troubleshooting capabilities Oracle has provided for when this happens I was unable to get it to restart leaving me up the creek as to Grid Control.

Ok, so Grid Control is down, simple, just deinstall using the Oracle Universal Installer and reinstall right? I ran OUI and selected the agent and OMS homes for deinstall, the OUI GUI puttered around a bit and then notified me it had successfully removed the selected product. Right, except for directories and registry entries. Ok, so I manually remove the remaining directories and the registry keys and reboot to eliminate the services that OUI didn’t deign to cleanup. Now finally, I can reinstall; no software, no registry entries, no directories and no services to cause me heartache.

So starting up OUI I begin the reinstall of the Grid Control. It gets all the way to the Configure the OMS Repository and then falls over dead with cryptic error screens pointing you to not one but two log files. Believe me the most important is located in: $ORACLE_OMSHOME$\oms10g\sysman\log and will be named something like:
“emca_repos_create.log”. Guess what? OUI also doesn’t remove the SYSMAN (the repository owner) user. Ok, no biggie, I just issue a “DROP USER SYSMAN CASCADE;” command and do a restart.

Oops…OUI now complains that there is a pesky ROLE it wants to recreate…MGMT_USER. Ok, I drop that and restart the repository build. Another 10-15 minutes later it complains about a public synonym that starts with MGMT…so I build a script to drop all public synonyms that begin with MGMT and then restart.

Oops…OUI now complains about another set of synonyms that begins with SMP, so I delete all of them. You guessed it, another restart, another 15 minutes and it complains about public synonym ECM_UTIL, so again I drop the synonyms (only 1 this time) beginning with ECM and restart…finally it completes and goes on to the end.

Here is the script I finally ended up with:

Now some of the drops may be not needed such as the MGMT$ synonym drops, but I left them in anyway.

So, hopefully if you run into the same issue I did with OEM this little script will help you to get it reinstalled.
