Test or migration coupling configuration

You can run a test or migration coupling facility to test and develop data sharing applications. You can define a test or migration coupling facility LP on the same CPC where other LPs are:

• Running z/OS® images connected to the coupling facility
• Running non-coupled production work

A single CPC configuration has the following consideration:

• Simultaneous loss of the coupling facility and any z/OS images coupled to it (a more likely possibility in a single CPC configuration) can potentially cause extended recovery times

You can define a test or migration coupling facility with or without coupling facility channel hardware. See Defining internal coupling channels (TYPE=ICP) for information about how to define a test or migration facility without coupling facility channel hardware.
