The XCF connection works within a SYSPLEX and provides a very fast connection over a Channel connection or through a Coupling Facility. XCF connections are limited to a SYSPLEX's boundaries. Connections outside a SYSPLEX require defining TCP/IP connections. These are discussed in the next section.
The XCF connection is controlled by the XCF() keyword in the GSINIT00 CAGSPARM member.
XCF(ON) or XCF(YES) tries to establish or connect to an XCF GROUP. XCF(NO) or XCF(OFF) prevents the XCF connections from being active. XCF(YES) is the default. If you don't want these connections to be established, you must change the Option to OFF or NO.
The GSXCF00 CAGSPARM member contains overrides for the XCF connection. The GROUP keyword allows you to change the name of the XCF Group that will be used. The default name of CAGSERV will be used if the member is empty or does not exist. Specifying GROUP(name) allows you to change this name.
If you do not make any changes to the default installation, CA GTS will start the XCF connection using group CAGSERV.
