      This chapter describes several areas to consider when planning the configuration for your installation. It explains connections between HCL Workload Automation for Z systems and provides some examples of basic configurations.
      - Planning considerations
        HCL Workload Automation for Z 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.
      - How to connect HCL Workload Automation for Z systems
        HCL Workload Automation for Z systems can be connected by using any of the following methods.
        TCP/IP
        HCL Workload Automation for Z uses Transmission Control Protocol/Internet Protocol (TCP/IP) to connect a tracker to the controller using a TCP/IP link.
        z/OS cross-system coupling facility
        HCL Workload Automation for Z uses the z/OS cross-system coupling facility (XCF) to connect HCL Workload Automation for Z systems using XCF communication links.
        VTAM® (network communication function)
        HCL Workload Automation for Z uses the network communication function (NCF) to connect a tracker to the controller using a VTAM® link.
        Shared DASD
      - Workstation destination
        The various physical and logical locations where tasks are performed at your installation are represented in HCL Workload Automation for Z 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 HCL Workload Automation for Z 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 HCL Workload Automation for Z configuration.

TCP/IP

HCL Workload Automation for Z uses Transmission Control Protocol/Internet Protocol (TCP/IP) to connect a tracker to the controller using a TCP/IP link.

The controller transmits work to the tracker through TCP/IP, and the same connection is used to pass back event information. The scheduler uses TCP/IP also to connect a distributed agent to the server. The TCP/IP connection between the server and the clients is established by the server.
