Using the Cross-System Coupling Facility (XCF) - ibm.com
The cross-system coupling (XCF) services provide the following functions that a multisystem application or subsystem programmer can use: A way to define a collection of unique parts of a program, and a way for each part to identify the other parts so they can work together.

IBM XCF - Wikipedia
In IBM mainframes, a Cross-system Coupling Facility, or XCF, is a component of z/OS that manages communications between applications in a sysplex. Applications may be on the same system or different systems. Systems communicate using messages transported by one of two mechanisms: Dedicated channel-to-channel links (CTC links).

Displaying cross system coupling facility (XCF) information
Parameters XCF Displays a summary of the current sysplex. PATHIN or PI Displays in message IXC355I the device number of one or more inbound signalling paths that XCF can use and information about inbound XCF signalling paths to this system.

Parallel Sysplex Performance: XCF Performance ...
Some installations implementing parallel sysplex have seen performance issues due to XCF signaling. These performance issues are generally solved by tuning changes to the XCF transport class definitions, buffer definitions, and signaling paths. This document is intended to review recommended XCF configurations and known performance tuning options.

z/OS Parallel Sysplex® Update and New XCF Client/Server APIs
z/OS 1.10 or later with the PTFs for APAR OA32807. A new version of the z/OS Coupling Facility Resource Manager (CFRM) Couple Data Set (CDS) is required in order to define more than 1024 CF structures to z/OS. z/OS allows up to 2048 structures to be defined, but at most 2047 could be allocated due to the smaller CF limit.

z/OS Parallel Sysplex Configurations - CA Technologies
If you operate z/OS in a parallel sysplex configuration, CAICCI can take advantage of XCF and XES hardware to provide high performance messaging between members of the sysplex. Use XCF or XES to achieve high-bandwidth connections between z/OS systems in a sysplex, without the need for a network protocol such as TCP/IP or VTAM. Contents

A z/OS Sysplex - publib.boulder.ibm.com
A z/OS Sysplex. Figure 24 shows four systems, each connected by cross-system coupling facility (XCF) communication links.. System A is the controlling IBM Tivoli Workload Scheduler for z/OS system and Systems B, C, and D are controlled systems.

XCF Groups - IBM
XCF Groups. A IBM Tivoli Workload Scheduler for z/OS XCF system consists of one controller and one or more trackers defined as members in the IBM Tivoli Workload Scheduler for z/OS XCF group. You can include one or more standby controllers in the group.

Some installations implementing parallel sysplex have seen performance issues due to XCF signaling. These performance issues are generally solved by tuning changes to the XCF transport class definitions, buffer definitions, and signaling paths.
