Can't log from OEM to database
I am using OEM 13.5 with a db repository 19.4 on linux enterprise edition 7
I have a test database that gets refreshed every three months. I change the sys and system passwords manually after the refresh takes place.
I have in the OEM a named credential for this database which have been working for years now.
I tried to access the database last week on Thursday to check its performance while some testing was underway but I got
ORA-01017: invalid username/password; logon denied
I went to the database and verified I had given the right password to the sys and system users, run the script again and went back to OEM and had the same error.
