Controlled systems

A controlled z/OS system requires a tracker. Communication with the controlling system is through TCP/IP, XCF, or NCF. The tracker writes event records to an event data set, and transfers the records to the controlling system if connected using TCP/IP, XCF, or NCF. NCF uses ACF/VTAM to link IBM Z Workload Scheduler systems.

If you use XCF for communication, you can include a standby Z controller on one or more controlled systems. A standby Z controller is started in its own address space. It can take over the functions of the Z controller if z/OS fails or if the Z controller itself fails. It cannot perform the functions of a tracker while in standby mode.

The Z controller also controls the workload in the end-to-end scheduling with z-centric capabilities environment.
