Setting a usage limit with workload groups
Workload groups allow you to set a usage limit for a licensed program by restricting the number of processor cores that are available to be used by the licensed program with a given logical partition.
Without workload groups, a licensed program's usage count for a given partition is calculated by using the full configured processingcapacity of the logical partition. With workload groups, a licensed program and all of its workloads are associated with a workload group. This allows the licensed program's usage count for a given partition to be based on the maximum capacity of the workload group.
Limiting the usage count of a licensed program to a value less than the full configured processing capacity of a partition can affect the licensing of a product. A licensed program owner can choose to recognize the workload group maximum processor core limit as an acceptable usage count for the product. If the licensed program owner accepts the workload group maximum processor core limit, they can then choose to provide a reduced cost license key reflecting the reduced core capacity of the workload group.
- Only those licensed programs that use the *PROCESSOR usage type can be licensed using a workload group.
- IBM® i is not eligible for licensing using a workload group.
- Any given licensed program can be associated with only one workload group.
- The processor core limit for a workload group represents the local usage count for any licensed programs associated with the workload group. The global usage count is a sum of the usage of the licensed product across all the IBM i partitions in a system. The global usage count may exceed the core limit of the workload group.
