Installed Oracle 11g. When you open localhost:1158/em - the message: "The database is down. Please specify the host credentials to access database restart and diagnostics tools." After entering the command: Code (Text): emctl status dbconsole It is reported that Oracle Enterprise Manager 11g is running. When you type: Code (Text): emctl status agent states that the agent works. Can you please tell how to solve the problem? Translated by Google Translate.
