Threshold options ignored for system relation area

  Explanation:  The storage area that contain the system relations
  must have UNIFORM page formats.  Either through the use of the
  defaults, or by directly specifing THRESHOLD options, SQL has
  been told to apply threshold options for the area containing the
  system relations.  SQL is ignoring those options.

  User Action:  None.  This is an informational message.  The user
  might want to change the command if it originated in a command
  file.  This may avoid confusion later.
