inaccessible AIJ file forced image exit to protect database

  Explanation:  To maintain the integrity of the database, the
  database system has forced your image to exit.  An error has
  been encountered with one or more of the after-image journals
  that could jeopardize your ability to recover the database
  should a it become necessary to restore and recover the
  database.  Until the journaling problem has been remedied no
  further updates to the database are allowed.

  User Action:  The RMU or DBO /DUMP/HEADER=JOURNAL command will
  display the current state of the journals.  Various remedies are
  possible, depending on the error encountered.  Contact Oracle
  Support if you have questions on how to fix the problem.
  Typically, disabling and re-enabling journaling is the simplest
  way to restore operation of the database.  This can be done
  using the DBO or RMU SET AFTER command, or from interactive SQL.
  After the journaling problem has been resolved a full database
  backup must be done to ensure that the database can be restored
  and recovered successfully in the future.
