When_to_Run_AUTOGEN

   VSI recommends that you run AUTOGEN in the following
   circumstances:

   o  During a new installation or upgrade.

   o  Whenever your work load changes significantly.

   o  When you add an optional (layered) software product. Certain
      layered products might require you to execute AUTOGEN to
      adjust parameter values and page and swap file sizes. (For
      information about using AUTOGEN to modify page and swap files,
      refer to the chapter on managing page, swap, and dump files
      in the VSI OpenVMS System Manager's Manual.) Refer to specific
      product documentation for installation requirements.

   o  When you install images with the /SHARED attribute. The
      GBLSECTIONS and GBLPAGES parameters might need to be increased
      to accommodate additional use of global pages and global
      sections.

   o  During normal operation, as part of a batch-oriented
      command procedure that runs AUTOGEN on a regular basis and
      automatically sends a report to an appropriate Mail account.
      The recommended procedure is described in the chapter on
      managing system parameters in the VSI OpenVMS System Manager's
      Manual.

   After a new operating system installation or upgrade, examine the
   results of calculations that AUTOGEN made to determine whether
   AUTOGEN has set system parameter values that are appropriate for
   your workload requirements.
