This parameter indicates a value which serves as the multiplier for the number of concurrently active duplication jobs that can access a single storage unit. This parameter applies to tape media.
Storage unit configuration includes limiting the number of jobs that can access the resource at one time. (The Maximum concurrent write drives value.) This value specifies the optimal number of jobs that the Resource Broker can consider running on that resource.
This parameter helps administrators ensure a balance in the following situation:
To overload the Resource Broker with jobs that it can't run is not prudent.
Make sure that there's enough work that is queued so that the devices won't become idle. The TAPE_RESOURCE_MULTIPLIER entry lets administrators tune the amount of work that the Resource Broker can evaluate for a particular storage unit.
For example, a particular storage unit contains three write drives. If the TAPE_RESOURCE_MULTIPLIER parameter is set to two, then the limit on concurrently active jobs is six. Other duplication jobs requiring the storage unit remain queued.
