par_manual_allocation.wlm

Chapter 9 305

# Dependencies:

# This example was designed to run with HP-UX WLM version A.03.00 or

# later. (A.03.00 was the first version to support strictly

# host-based configurations.)

# To implement WLM’s dynamic partition resizing:

# 1. Set the primary_host keyword in this file

# 2. Copy this WLM configuration to each partition in the system

# 3. Adjust the priority for the SLO named slo_myslo to reflect the

# priority of the applications for the current partition relative

# to the priority of the applications in all the other partitions

# 4. Customize the configuration file

# par_manual_allocation.wlmpar used by the WLM global

# arbiter (see that file for details)

# 5. Activate the par_manual_allocation.wlmpar file on the

# primary host:

# wlmpard -a par_manual_allocation.wlmpar

# 6. Activate the WLM configuration file on each partition:

# wlmd -a par_manual_allocation.wlm

# NOTE: You will activate both the par_manual_allocation.wlmpar

# file and the par_manual_allocation.wlm file on the primary

# host.

# 7. Change the number of cores a partition requests using wlmsend

# Using the wlmsend command on a partition, you can explicitly

# request a certain number of cores for that partition. The

# configuration below defines a metric named num_cpus. You can

# change the value of this metric with wlmsend. For example, the

# following command requests 3 cores:

# % /opt/wlm/bin/wlmsend num_cpus 3

# After using wlmsend, wait one wlm_interval (set at 5 seconds

# below) then use the wlminfo command from the next step to see

# how the group’s allocation is affected. Continue changing the
