ORA-00262
        current log string of closed thread string cannot switch log
        
        
        Cause
        The log cannot be cleared or manually archived because it is the current log of a closed thread. Also, it was not possible to switch logs because another log was current. All other logs for the thread must be either archived, or cleared, and cannot be reused.
        Action
        Either archive another log in the same thread first, or clear the log. For more information on why the switch cannot be completed, see attached errors.
