This space provides the same content as before, but the organization of the home page has changed. The content is now organized based on logical branches instead of legacy book titles. We hope that the new structure will help you quickly find the content that you need.

DFLTGRP parameter

The optional DFLTGRP parameter identifies the Cross-System Coupling Facility (XCF) group name that is to be used at CAS startup.

This parameter uses the following syntax:

DFLTGRP={BBGROUP | name}

The default is BBGROUP.

DFLTGRP can be used during migration from one release of MainView to another. You can use it to start a test CAS on a system image that is already running a production CAS. By specifying different XCF group names, you can run two CASs on the same system image.
