To associate an XCF group and its members with a transport class, you need to know its XCF group name. XCF group names for some MVS™ components and IBM® products are included in the discussion of Group Names and members for MVS components and subsystems.

You also need to know the XCF group names for any other multisystem application programs that communicate among members on various systems. An application programmer who codes a multisystem application that uses signaling services should give you the application's XCF group name so that you can designate transport class(es), if needed, for the group's use. Otherwise, for a list of the XCF groups defined on the system, you can issue the DISPLAY XCF,GROUP command or run the RMF™ XCF Activity Report.
