HP-UX Workload Manager overview

After you have activated a configuration using -t, use the wlmaudit command to display the audit

data. The wlmaudit command enables you to specify a date range for the data to display. By

default, the output is plain text. However, you can display output in formatted HTML as well.

Managing nested partitions

You can manage any combination of FSS and pSet workload groups inside virtual partitions inside

nPartitions. (Instant Capacity must be installed on the nPartitions to simulate movement of cores among

the nPartitions.) For example, consider the system shown in Figure 5, consisting of three nPartitions.

Two nPartitions each have three virtual partitions, while the third partition has two FSS workload

groups and a pSet-based workload group. Each virtual partition or workload group consists of a

workload with an SLO. WLM enables you to focus on the workloads and their goals. With the WLM

management of nested partitions, the resources needed to satisfy those goals can come from other

workloads in the nPartition, as well as from other nPartitions. The arrows in the figure indicate the

possible sharing.

Using HP-UX Workload Manager on multiple servers

WLM manages workloads on individual servers. To manage workloads on multiple servers, install

and configure WLM on each server.

WLM can be integrated with HP Serviceguard by storing the WLM configuration file in a file system

shared by all nodes in the cluster and then activating the configuration on each node independently.

Alternatively, you can use the HP Integrity Essentials Global Workload Manager (gWLM) to manage

workloads across multiple servers. gWLM enables you to define resource-sharing policies that can be

used across servers. For more information on gWLM, go to http://www.hp.com/go/gwlm.
