class, the associated performance objectives, and the availability

or override the number of servants that are active. With this task,
you can enable WLM to start additional servants to meet performance
goals.

Results
Workload Management (WLM) can start additional servant regions
to meet performance goals, based on the importance of its work compared
to other work in the system, the availability of system resources
that are needed to satisfy those objectives, and a determination by
WLM of whether starting more address spaces might help achieve the
objectives. It is also important to make the goals reasonable.
