unknown database recovery process -- DBR image not invoked by
  database monitor

  Explanation:  An attempt to bind to the database was made by a
  database recovery process (DBR) that was not created by the
  database monitor; this would happen if the DBR image was invoked
  from DCL by the user instead of the monitor.

  User Action:  DO NOT attempt to execute the DBR image from DCL.
  The database monitor will invoke the database recovery process
  to perform database recovery.
