HP UX 11i Workload Management (gWLM/WLM) Software manual Combining psets and virtual partitions

(Windows), increase the CMS database cache size by increasing the value of the com.hp.gwlm.cms.cachesize property by 25%. (The cache is more memory efficient if the size is near a power of 2. If your target cache size is close to a power of 2, round it up to the next power. For example, if your target cache size is 60,000, round it up to 66,000.)

2.Stop and restart gwlmcmsd using the following commands.

NOTE: Stopping gwlmcmsd disables HP Matrix OE visualization and Capacity Advisor.

#gwlmcmsd --stop

#gwlmcmsd

Combining psets and virtual partitions

When using psets on virtual partitions, assigning CPUs to virtual partitions by either path or cell specification can result in processes losing their processor set affiliations when CPUs are removed.

Workaround

Two workarounds are available:

•Do not assign CPUs to virtual partitions by either path or cell specification.

•Set the gWLM policy minimum for pset 0 (the default/OTHER workload) to be greater than or equal to the sum of path-specific CPUs and cell-specific CPUs.

Error during discovery of compartments

The following message might be displayed when you use the Manage New Systems wizard or the gwlm discover command:

Error during discovery of compartments.

In addition, the /var/opt/gwlm/gwlmagent.log.0 file contains the following message:

com.hp.gwlm.common.PlatformException: /usr/sbin/parstatus -w exited

with a non-zero exit status. Captured stderr is: Error: Unable to get the local partition number.

Workaround

This is most likely due to having an outdated version of the nPartition Provider software. Global Workload Manager uses a command that is made available by the nPartition Provider, which is typically in every version of HP-UX, to determine system capabilities.

You can also use the /opt/vse/bin/vseassist command to diagnose the issue. Install the latest nPartition software, even if you are not using nPartitions.

For HP-UX 11i v1, use version B.11.11.01.03.01.01 or later.

For HP-UX 11i v2 on HP 9000 servers, use version B.11.23.01.03.01.01 or later. For HP-UX 11i v2 on HP Integrity servers, use version B.11.23.01.04 or later. You can find the nPartition Provider at the following locations:

•The quarterly AR CD starting May 2005

•The Software Depot website: http://software.hp.com

Modifying Java while gWLM is running

gWLM does not support any actions (including the use of update-ux) that remove, overwrite, or otherwise modify the version of Java that gWLM is using in a managed node or CMS that is part of a deployed SRD.
