Server

IBM Z Workload Scheduler provides a server you use to access the controller remotely from ISPF dialogs, PIFs, and the Dynamic Workload Console interface. Connections with the server run through Advanced Program-to-Program Communications (APPC) sessions or Transmission Control Protocol/Internet Protocol (TCP/IP). The server runs in its own address space; however, it is optional if you do not access the controller remotely.

The server is also used to communicate with the distributed agents for the end-to-end scheduling with fault tolerance capabilities.

Using a Started Task JCL you start and stop one or more servers either individually, using the Start and Stop operator commands, or automatically with the controller, using a keyword in the OPCOPTS statement. A server must start on the same z/OS image as its controller. Only one server can be started with the end-to-end scheduling with fault tolerance capabilities active.

The PIF dialog connection to the controller, whether via server or subsystem interface, is allowed only when the code is at the same level on both sides of the interface.
