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.
