    Cool Unanswered: Ora-12545

    ORA-12545 Connection failed because target host or object failed

    I have a newly created instance of 9i and when I attempt to login this is the error I get. Any ideas?

    Ensure your TNSNAMES is setup properly ... That message means that the
    service name you are trying to attach to can't be found. Usually a problem
    with the wrong IP or Hostname in TNSNAMES ... Also ensure that the listener
    (and database) are both up and running ...
