I have been trying to find the problem for 2 days and think it's time to ask someone else... My "TEST" database was set up, configured and I was able to log into the OEM. Now I can't do that... I am getting "Invalid Option for Alter Session" when I type in any login that I normally used before. I have de-installed OEM and components, and tried to reconfigure and still no luck. I have looked at the sqlnet, tnsnames, listener, and init files thinking I would find a problem... It looks ok to me. I have one instance named orcl... I have gone into the svrmgr and done the connect Internal... and granted sysdba and sysoper to system... still can't log in or start the service.

Can someone tell me what else it might be ?

Thanks so much, Cadence
