Define the z/VM CF Service Machines to z/OS

Before z/OS® can use the z/VM® Guest Coupling Simulation support, the administrative policy data in the Coupling Facility Resource Manager (CFRM) must be updated to define the CF Service Machines to z/OS. The following is the JCL required to define our sysplex. The sysplex will use two z/VM CF Service Machines. The first CF Service Machine user ID is CFCC1 and the second one is CFCC2.

The information for TYPE(), MFG(), PLANT(), and SEQUENCE() can be obtained by using the CP QUERY MSGPROC command (see Verify the Sysplex Configuration). The TYPE(). MFG(), and PLANT() information will always be the same when using z/VM Guest Coupling Simulation support. The SEQUENCE() value must be unique and is based on the user ID of the CF Service Machine. For more information about z/VM's fabricated Node Descriptor, Refer to Node Descriptor (ND) Support for the Message Processor.
