Hi.

Sounds to me like the OEM repository is out of sync with the real status of the DB.

When this has happened to me I've run the "emca -r" command to reconfigure OEM.

It asks you a few questions and then does the business. The "-r" option tells it that the repository is already present in the SYSMAN schema. Without this is fails becaue it can't create the repository tables.

Once this is complete you should be able to login as normal.

This has happened a number of times to me, without any definite set of circumstances leading up to it. I guess it's a bug

Cheers

Tim...
