    You database is not online...

    Talk to the DBA to confirm that the instance is up and running and verify that the connection information provided to you is correct.

    If it is a local database (maybe an XE edition) then check is the service is running.

    You should provide more information (version & edition, platform, conneciton details, etc) in order to be able to help.
