Resource Amount, Weight, and Usage

The jobset resource profile references a previously defined CA NSM resource profile that describes resources required by the jobs in the jobset. Amount describes how much of this resource is needed. Weight indicates the relative importance of a resource. Usage indicates how this resource will be used by the jobs in the jobset and can be specified as one of the following:

• PRIVATE—each job needs exclusive access to a resource.
• SHARED—multiple jobs share a resource.
• COREQ—jobs can access the resource only when another job has PRIVATE access.

  Note: COREQ control typically is used to direct jobs that have a particular service to the CPU where the system is active. Consider, for example, a job that has a CPU dependency of Any available CPU and requires a co‑requisite resource named db. This job can only run on a CPU where another job, which has PRIVATE use of the resource db, is currently active.

An example of resource allocation follows. Assume that an existing resource profile named tapedevs specifies that four tape drives exist on station europa.

The following Jobset ‑ Detail Resources window indicates that each job in the jobset requires one of the four tape drives defined as available resources by the previously defined resource profile named tapedevs, and each job needs exclusive access to the tape drives.

Note: The CA NSM JM Option does not verify the physical existence or actual availability of tape drives or any other device. These resource definitions are logical rather than physical.
