This section provides a quick overview of various commands associated
with using WLM in a PRM-based configuration (using FSS or
PSET-based workload groups and confined to a single instance of
HP-UX). For information on using WLM in host-based configurations
designed for moving cores across virtual partitions and nPartitions, see
Chapter 7, “Managing SLOs across partitions,” on page 255. To become
familiar with how WLM moves cores across partitions, see the
par_usage_goal.wlm and par_usage_goal.wlmpar configuration files in
/opt/wlm/examples/wlmconf/ and also included in Chapter 9, “Example
configuration files,” on page 283. The files includes steps to take for
implementing migration across partitions.
This chapter takes advantage of some of the configuration files and
scripts available in the directory /opt/wlm/examples/userguide/ as well as
at the following Web site:

NOTE You can define FSS or PSET-based workload groups and use WLM
partition management in the same WLM configuration. Certain
software restrictions apply to using PSET-based groups with virtual
partitions (vPars), Instant Capacity, and Pay per use. For more
information, see the WLM Release Notes (/opt/wlm/share/doc/Rel_Notes).
On HP-UX 11i v1 (B.11.11) systems, you must install PSET (PROCSET)
software to obtain PSET functionality; see the HP-UX WLM Release
Notes. PSET functionality comes with HP-UX 11i v2 (B.11.23) and
HP-UX 11i v3 (B.11.31) systems.
To become familiar with WLM, how it works in PRM-based
configurations, and some related commands, complete the following
procedure:
NOTE For this procedure to work, PRM must be installed on your system.
