Planning your configuration
This chapter describes several areas to consider when planning the configuration for your installation. It explains connections between IBM Z Workload Scheduler systems and provides some examples of basic configurations.
Planning considerations
IBM Z Workload Scheduler must recognize when events occur; for example, when a started task or job begins to run or terminates, or when a data set has been printed. It uses JES and SMF exits to obtain this information from z/OS and to create event records describing the changes in the system.

        Communication
      - How to connect IBM Z Workload Scheduler systems
        IBM Z Workload Scheduler systems can be connected by using any of the following methods.
      - Workstation destination
        The various physical and logical locations where tasks are performed at your installation are represented in IBM Z Workload Scheduler by workstations. Each workstation groups related activities. Every operation in the application description database and the current plan is associated with a workstation. You define workstations in the workstation description database.
      - Workload restart
        You can use workload restart (WLR) to restart and reroute work in your IBM Z Workload Scheduler configuration. WLR tracks the status of workstations. It can be invoked when a workstation becomes inactive; that is, when the controller cannot communicate with the tracker at the destination that the workstation represents.
      - JES considerations
        The JES type and configuration in your installation has implications on your IBM Z Workload Scheduler configuration.

Planning considerations

IBM Z Workload Scheduler must recognize when events occur; for example, when a started task or job begins to run or terminates, or when a data set has been printed. It uses JES and SMF exits to obtain this information from z/OS and to create event records describing the changes in the system.

The event records are stored in a sequential file called the event data set identified by the EQQEVDS DD name.

IBM Z Workload Scheduler also uses the event data set to write checkpoint information for submission requests. The first record of the data set is used for this purpose, so the EQQEVDS DD name must be specified for all IBM Z Workload Scheduler address spaces. The same data set can be used for both submit checkpointing and the event-writer subtask.
