I am an instructor for a local College of Technology. I am supporting Oracle 10g release 2. I created a database some time ago for one of my classes. All went well and worked correctly. Recently, I added another database using the DBCA. Now, I cannot access the OEM attached to the database I first created. When I try to login I get an error message stating: "The application requires more database privileges than you have currently been granted. Click on Help to get more version specific information." I have tried to login as sys, and system. When I try to login in as sysman I receive the error message: "ORA-28000: the account is locked". I never locked the account and I had been able to access the OEM prior to this point. I can still access the database via SQL Plus -- but I need the OEM. Can anybody help me? What went wrong? I can access the OEM for the new database I added.

Thank you for your help.
