Note: If you did not set workload balancing capabilities for the CA NSM JM Option, go to How to Schedule Work by Dates. Identifying resource requirements is necessary only if you will be using advanced workload balancing.
The CA NSM JM Option maintains a list of available resources and the special resource requirements of any given job to automatically balance an active workload. This feature is typically referred to as workload balancing. Workload balancing enables the CA NSM JM Option to avoid bottlenecks and resource contention problems on a single computer or across a network of computers.
Tape drives, for example, are serial‑use devices. It would be inappropriate to simultaneously submit two jobs, each requiring a tape drive for processing, on a computer that has only one tape drive. Between these two unrelated jobs, a special resource requirement would exist that requires coordination (in this case, serial processing).
To derive maximum benefit from workload balancing, you must identify those resources that have special usage or access coordination requirements and define them to the CA NSM JM Option as resource profiles.
Changes made to resource profiles affect all jobsets and jobs that reference the resources, including work currently scheduled for processing (entries in the tracking file). Work currently scheduled for processing can be monitored or updated using Jobset Status and Job Status.
For procedures to identify resource requirements, see Defining Resource Profiles in the online CA Procedures.
