Create Schema Baseline fails with "Could not connect to database.."
As above, when I try to create a schema baseline, I get error as follows:
Error
Examine and correct the following errors, then retry the operation:
Source Database - Could not connect to database. Make sure the database is up and preferred credentials (if set) are valid.
The database is definitely up and I have tested my preferred credentials repeatedly with success.
I have DBA role in the database and I am a Super Administrator in OEM so I cannot understand why this is not working. Someone please advise which credentials might be wrong or where I should look for more detailed error output.
