Avoiding corruption of the current plan backup

If an error occurs in the current plan while IBM Tivoli Workload Scheduler for z/OS is running and is not detected by IBM Tivoli Workload Scheduler for z/OS, it is strongly recommended that you cancel the controller address space instead of stopping it as is normally done. This prevents copying a logical error from the active current plan to the alternate current-plan data set during the backup process. When IBM Tivoli Workload Scheduler for z/OS is restarted, the active current plan will be re-created from the alternate current plan. This will remove any errors in the active current plan.

If IBM Tivoli Workload Scheduler for z/OS recognizes that the active current plan is damaged or is no longer accessible, a recovery of the active current plan is performed automatically. This is described in Current-plan recovery processing.
