ORA-00259
        log string of open instance string (thread string) is the current log, cannot archive
        
        
        Cause
        An attempt was made to archive the current log of an open thread. This was not allowed because the redo log file might be in use for the generation of redo entries.
        Action
        Force a log switch in the instance where the thread is open. If no instances are open, then open the database so that instance recovery can recover the thread.
