FOCUS includes an intelligent procedure named ISETUP for applying a service pack. ISETUP refers to this function as a Refresh. The ISETUP procedure can also upgrade to a new version of FOCUS. ISETUP refers to this function as an Upgrade.

ISETUP can also download and apply a service pack from an Information Builders FTP site.

Note: In order to receive a service pack or upgrade electronically, you must use a z/OS ID that has access to FTP, TSO RECEIVE, and to the production and test FOCUS libraries.

The ISETUP procedure simplifies the update process by:

• Requiring less interaction.
• Automating most of the procedure.
• Remembering and reapplying all of the required system settings, for example site code and CPU ID.
• Providing a log of all the activity that takes place to allow for verification.

There are aspects of the upgrade or maintenance process that are not handled by ISETUP. These are detailed in this document and still require manual intervention.
