Interval option 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 the INTERVAL option, SQL has
  been told to apply the INTERVAL option for the area containing
  the system relations.  SQL is ignoring that option.

  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.
