OCI-00354
        corrupt redo log block header
        
        
        Cause
        The block header on the redo block indicated by the accompanying error, is not reasonable.
        Action
        Do recovery with a good version of the log or do time based recovery up to the indicated time. If this happens when archiving, archiving of the problem log can be skipped by clearing the log with the UNARCHIVED option. This must be followed by a backup of every datafile to insure recoverability of the database.
