HP-UX 11i Version 2 Release Notes (October 2003)

General System Administration

HP Partitioning

Chapter 4

• wlminfo utility for monitoring workloads and their SLOs

• auditing and billing information

• PSET-based workload groups can now have their number of CPUs adjusted based on

SLOs

• passive mode to allow you to see how WLM will approximately respond to a given

WLM configuration

• ability to easily capture the stderr of data collectors by using coll_stderr in your

WLM configuration

• ability to temporarily remove groups with no active SLOs by using the

transient_groups keyword, ensuring that resource use is reduced to zero for such

groups

Impact

HP-UX WLM version A.02.01.01 offers greater functionality and ease of use.

Compatibility

There is a new /etc/rc.config.d/wlm file. If you've modified your

/etc/rc.config.d/wlm file, the new file is placed in

/opt/wlm/newconfig/etc/rc.config.d/wlm.

Performance

HP-UX WLM version A.02.01.01 improves application performance once you have

properly configured workload groups for critical applications. Applications that are not

placed in workload groups may experience performance degradation. Additionally,

misconfiguring WLM can degrade performance.
