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.

If an operation is restartable, it can be started again after a workstation failure. If an operation is reroutable, it can be moved to an alternative workstation for running when its workstation is no longer active.

For WLR purposes, the status of a workstation can be either active or inactive. An inactive workstation has a status of offline, failed, or unknown. The actions that WLR performs depend on the new status of the workstation and on the values you specify on the WSFAILURE and WSOFFLINE keywords of the JTOPTS initialization statement. The inactive status that a workstation can have depends on the type of connection between the tracker and the controller. The connection type and the new workstation status determine whether workload restart actions can be invoked automatically. You can use the full capabilities of WLR on systems that are connected by XCF.

Note: JES also has restart functions, which can be used when the system is restarted after a failure. JES can restart jobs that were active when the failure occurred. To prevent jobs from being started twice, ensure that both JES and WLR do not perform restart actions for jobs on the failing system.
