As data centers work toward the goal of providing round-the-clock availability of both their systems and applications, CA Datacom provides a solution through use of a Shadow MUF for both planned and unplanned outages on a system running the database engine.

This article will provide links to resources to help understand the functionality and configuration of the Shadow MUF.
