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.
