TCP/IP connected

Figure 4 shows two Tivoli Workload Scheduler for z/OS address spaces with a TCP/IP connection on a z/OS system.

You represent this system to the scheduler by defining a computer workstation with a destination field that specifies the destination name of the tracker. The controller transmits JCL, release commands, WTO messages, and cleanup requests across the TCP/IP link. The tracker receives data across the TCP/IP link and performs the following actions:

The event-tracking routines create event records to describe activities that occur on the system. These records are added to the tracker event writer queue in ECSA. The tracker processes the queue, transmits the records to the controller across the TCP/IP link, and writes the events into the event data set. The IP task in the controller receives the event records, and the current plan is updated.

Note:
You must specify EQQEVDS for a controller, even if an event writer is not started in the controller address space. The EQQEVDS data set is used for submit checkpointing. It can be the same data set that is used by an event-writer function. Use a unique EQQEVDS for each address space of the scheduler.

The graphic shows a system with a TCP/IP link between the controller and tracker.

Table 6 shows the initialization statements you can use to create the configuration in Figure 4.

In this example, the name of the destination is DEST1. The destination name is defined also in the destination field of the workstation.
