Migrating from WLM to gWLM
25
Migration example: vPar-based workloads with usage goals
As with WLM, you can manage virtual partitions with gWLM. gWLM greatly simplifies the
configuration however.
The WLM configurations
WLM requires two configurations to manage partitions: one for wlmd and one for wlmpard.
The two configurations below are based on the files par_usage_goal.wlm and
par_usage_goal.wlmpar, both available in /opt/wlm/examples/wlmconf/ on systems with WLM
installed.
First, we have the wlmd configuration file. This file is used in every virtual partition.
primary_host = myserver; # Change this value
tune {
wlm_interval = 5;
}
slo slo_myslo {
pri = 1; # Change this value
goal = usage _CPU;
}
Next, consider the wlmpard configuration file.
par {
interval = 10;
}
