unjournaled changes made; database may not be recoverable

  Explanation:  Changes have been made to the database while AIJ
  journaling was disabled.  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.

  User Action:  IMMEDIATELY perform a full database backup.
  Following successful completion of the full database backup, the
  after-image journals may be backed up.
