partially-journaled  changes   made;   database   may   not   be
  recoverable

  Explanation:  Partially-journalled changes have been made to the
  database.   This  may result in the database being unrecoverable
  in the event of database failure; that is, it may be  impossible
  to  roll-forward  the after-image journals, due to a transaction
  mis-match  or  attempts  to  modify  objects   that   were   not
  journalled.   This  condition  typically  occurs  as a result of
  replicating database changes using the Hot Standby feature.

  User Action:   IMMEDIATELY  perform  a  full  (not  by-sequence)
  quiet-point  AIJ  backup  to  clear  the  AIJ journals, followed
  immediately by a full (no-quiet-point allowed) database backup.
