The processing of the current day’s workload (work in the tracking file) is status-driven. The CA NSM JM Option constantly monitors and tracks jobs, moving jobs from one status level to the next only after specific conditions or requirements have been satisfied.
Jobsets and jobs advance through various status levels during workload processing. The autoscan process brings qualifying jobsets and jobs into the tracking file with an initial status of LOADNG. After all the new work is loaded, the CA NSM JM Option marks it WSTART (Waiting to Start). Autoscan is then complete.
After bringing all new qualifying jobsets and jobs into the current day’s workload (into the tracking file), the CA NSM JM Option processes the workload by reviewing:
Jobsets are processed first. Jobset criteria are evaluated prior to criteria for jobs in the jobset. First, the CA NSM JM Option checks that a jobset’s early start time has arrived; second, it checks to see if all predecessor requirements for the jobset have been satisfied.
When the jobset is in START status, the CA NSM JM Option looks at similar criteria for jobs in the jobset. A jobset must be marked as started (START) before its jobs can be evaluated. For example, when a job is in WSTART (Waiting to Start) status, the CA NSM JM Option evaluates its early start time. If the early start time has been reached, the job is placed in WPRED (Waiting for Predecessors) status. Otherwise, the job stays in WSTART until the specified early start time is reached.
The CA NSM JM Option prioritizes jobs based on resource requirements (if any), early start time, and priority. Although you can fine‑tune the sequencing of your workload using early start time and priority, you typically use predecessors as the primary means to establish the sequence of workload jobset and job processing.
When all the jobs in the jobset are complete, the jobset is marked complete (COMPL). A jobset is also marked complete if none of its jobs meet the criteria for selection, or if there are no jobs in the jobset.
To summarize, the CA NSM JM Option first looks at the jobset to determine that early start time has arrived and predecessor requirements are satisfied. The CA NSM JM Option then looks at the jobs in the jobset to determine that early start time has arrived, predecessor requirements are satisfied, and that resources, must complete time, and priority can be satisfied.
