  1. Please ensure that the database is started.
  2. If the database is started, probably the database has not yet registered with the listener. Generally, this issue is resolved by waiting a few minutes to allow the registration to complete.
  3. Check the following in the TNSNAMES.ORA
    1. SERVICE_NAME specified should be a service known to the Listener. Please run the command "lsnrctl services " to list the services known to the listener.
    2. Check the Oracle net connectivity (from client to server) using command "tnsping SERVICE_NAME ".
