This section is of interest to systems programmers who want to set up a multi-CPU environment in a sysplex, or who want to provide a communications link between Beta products on different LPARs.
BSA XCF is the BSA Cross Coupling Facility, which can be used to provide a communications link between Beta products on different LPARs in a sysplex or parallel sysplex. It supplements the current OCF protocol and can even be used to replace it; for example, XCF can be used for communication within a sysplex instead of OCF.
BSA XCF communication uses the extended capabilities of the Cross Coupling Facility (XCF) component of the z/OS operating system. It enables Beta products and CPUs to be accessed beyond LPAR borders without requiring the use of an additional task such as the OCF Cross System Router. Beta products and all the connected CPUs are readily available to online users and batch jobs throughout the entire sysplex.
The BSA XCF Global Connect component is a started task with its own address space that remains constantly active in the XCF environment. It facilitates XCF communication for Beta Systems products that do not set up their own Beta Systems product address space in the XCF environment, for example, _beta access.
