par_usage_goal.wlm

Chapter 9 311

# host-based configurations. It was also the first version that does

# not require mincpu/maxcpu statements; thus, this configuration file

# must be run on A.03.00 or later.)

# 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_usage_goal.wlmpar used by

# the WLM global arbiter (see that file for details)

# 5. Activate the par_usage_goal.wlmpar file on the primary host:

# wlmpard -a par_usage_goal.wlmpar

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

# wlmd -a par_usage_goal.wlm

# NOTE: You will activate both the par_usage_goal.wlmpar file and

# the par_usage_goal.wlm file on the primary host.

# 7. Monitor each SLO’s request for CPU shares, using the following

# wlminfo command:

# wlminfo slo -v [-l]

# The output will show the shares request (“Req” column)

# increasing for the partitions as the loads on those partitions

# increase.

# To monitor the partitions, use the following wlminfo command

# at the host on which wlmpard is running:

# wlminfo par -l

# The output will include information about the CPU resources

# associated with each partition.

# The primary_host keyword specifies the host name for the partition
