Controlled systems

About this task

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

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

The controller also controls the workload in distributed environments:
  • In the end-to-end scheduling with z-centric capabilities network.
