Dual JT log data set problems

When IBM Tivoli Workload Scheduler for z/OS finds an error with a dual job-tracking data set, the dual-logging process is disabled. The IBM Tivoli Workload Scheduler for z/OS current plan and normal job-tracking logs continue as normal. You should stop IBM Tivoli Workload Scheduler for z/OS, and reallocate the dual JT log data set. The dual-logging function is activated again when the controller is started.
