    27086, 00000, "unable to lock file - already in use"
    // *Cause: the file is locked by another process, indicating that it is
    // currently in use by a database instance.
    // *Action: determine which database instance legitimately owns this file.

    Other instances running on same box?

    Either way, ask sysadmin to check status of file /LOcation/DBISNTANCE/oradata/DBISNTANCE_redo02.log
