Each application that uses a coupling facility structure must provide the information necessary to define the structure in a CFRM policy. In z/OS®, information about the following structures for IBM® products can be found in the associated documentation.

Table 1. Coupling facility structures in z/OS for IBM products

Structure Function	Structure Type	User-Managed Rebuild	User-Managed Duplexing Rebuild	Alter	System-Managed Processes	Where Documented
XCF signaling	List	Yes	No	Yes	No	See Planning signaling services in a sysplex.
Note: For communications in the sysplex, JES3 uses the XCF signaling structure if it is defined. As a result, you do not need to define JES3 signaling structures in the sysplex. For information about JES3 and the sysplex, see z/OS JES3 Initialization and Tuning Guide.
