In the CA Workload Automation AE environment, a resource is a system component that can be quantified. Resources govern job execution and play a vital role in scheduling. Before starting a job, CA Workload Automation AE compares the resources required with the resources available. For example, you may have specified resource requirements that must be met before a job can run. If the required resources are not available, CA Workload Automation AE defers the job run until resources are available. There are two types of resources: real and virtual.
Real resources are resources that are physically associated with the system, such as memory, disk space, and CPU time. For example, consider a job that can run only when the available memory is greater than a specified value. In that case, CA Workload Automation AE starts the job only when the required memory is available.
Note: Real resources cannot be created or manipulated in CA WCC Resources.
Virtual resources are only representative and are not tied to a physical system. The number of licenses available to all machines controlled by CA Workload Automation AE is an example of a virtual resource. As each job that requires a license is submitted to the system, the number of licenses in the pool is decremented. When the number of licenses reaches zero, no more jobs can be submitted until the license pool is replenished.
