z/OS cross-system coupling facility

Tivoli Workload Scheduler for z/OS uses the z/OS cross-system coupling facility (XCF) to connect Tivoli Workload Scheduler for z/OS systems using XCF communication links.

When one or more trackers are connected to the controller through XCF communication links, the Tivoli Workload Scheduler for z/OS systems form an XCF group. The systems use XCF group, monitoring, and signaling services to communicate. The controller submits work and control information to the trackers using XCF signaling services. The trackers use XCF services to transmit events back to the controller.

XCF connections let Tivoli Workload Scheduler for z/OS support a hot standby controller and automatic-workload-restart functions.
