Use this panel to define the coupling facility definitions. You can also edit or delete existing coupling facility definitions. The coupling facility provides data sharing functions for multiple systems in the Parallel Sysplex configuration. A coupling facility runs as a special type of logical partition (LPAR) on a central processor (CP), defined through the Processor Resource Systems Management (PR/SM) logically partitioned mode (LPAR) feature.
Use an uninterrupted power supply for your coupling facility to ensure high availability. For recovery purposes, IBM recommends that you have at least 2 coupling facilities in your Parallel Sysplex configuration.
