ORA-01622
        thread number must be specified - default not specific
        
        
        Cause
        The thread was not specified when adding a log, and the currently mounted thread was chosen by default at mount time. Since the current thread was not specified explicitly the user cannot know which thread the log will be added to.
        Action
        Explicitly specify the thread number either in the INIT.ORA parameter "thread", or in the add command.
