A PLEX configuration

An HCL Workload Automation for Z PLEX environment shows four systems running in a sysplex environment, connected using cross-system coupling facility (XCF) communication links.

One controller and one tracker are started on each tracker image of the sysplex; one controller becomes the active one, while the others start as standby controllers. One server is started on the z/OS® image where the active controller runs, to handle requests from dialogs and PIF applications.

The &SYSCLONE system variable is assumed to be set to KA, KB, KB, and KC on systems A, B, C, and D respectively.
