Message Characteristics for XCF Groups

To define suitable transport classes for an XCF group, you must know the lengths, frequency and performance requirements for messages sent by the group.

For message information on MVS™ groups, see Message information for some MVS groups.
Coupling facility structures for IBM products provides reference sources for IBM® product applications.
An application programmer who codes a multisystem application that uses signaling services should provide you with the lengths, frequency, and performance requirements for messages sent by members of the group.

The RMF™ XCF Activity Report is another source of information about messages for the groups in the system.
