# configure WLM for dynamic partition resizing.
#
# The WLM global arbiter’s interval is set to 10 seconds. Every interval,
# the arbiter takes CPU requests from the WLM instances running on the
# partitions and makes changes in the partitions’ CPU allocations. (If you
# change the global arbiter interval, be sure it is greater than the
# wlm_interval value you use in any of the partitions’ WLM configuration
# files.)
#
# Several additional par structure keywords are included below but commented
# out. Use the port keyword to specify the port that the global arbiter
# should monitor for input from the various WLM instances. Specify a port
# number greater than 0. If you specify a port number, you must specify the
# same port number in each partition's WLM configuration file. The default
# port used by WLM is 9691. In the example below, port 9692 is specified.
#
# Use the wlmpardstats_size_limit keyword to automatically trim the global
# arbiter statistics log file /var/opt/wlm/wlmpardstats. This file is created
# when you use the -l option to wlmpard. Specify the file size (from 0 to
# 2048 megabytes) at which you want the file trimmed. The default is 0,
# which disables trimming. In the example below, the file would be trimmed
# when its size reaches 1024 megabytes.
#
# If Temporary Instant Capacity or Pay per use resources are available,
# you can optimize the use of these resources by specifying the utilitypri
# keyword. The global arbiter will then adjust the total number of active
# cores on the system to ensure that certain SLO resource demands are met.
# Specify an integer value greater than or equal to 1. This value determines
# the priority levels at which SLO demands will be met. In the example below,
# the value specified is 2, meaning that any available Temporary Instant
# Capacity or PPU resources are used whenever SLOs with a priority from 1 to
# 2 (inclusive) are demanding more CPU resources.
#
# See wlmparconf(4) for complete HP-UX WLM global arbiter configuration
# information.
