HP-UX Workload Manager A.03.00 Release Notes for HP-UX 11i v1 and HP-UX 11i v2

HP-UX Workload Manager Release Notes

What’s in this version

WLM A.03.00 provides the following new or changed functionality.

• Simultaneous management of virtual partitions and nPartitions

WLM now allows you to manage SLOs across the virtual partitions and nPartitions in a

single server at the same time.

For more information, see the wlmpard(1M) man page.

• Integration with Security Containment

The HP-UX feature Security Containment provides file and process isolation. WLM’s

integration with this feature allows you to create Secure Resource Partitions, which

combine the isolation of Security Containment and the resource allocation controls of

WLM.

For more information, see the scomp keyword in the wlmconf(4) man page.

• Secure communications

WLM’s communications can now be secured. Use the new wlmcert command to manage

security certificates, then use the -s option with wlmd, wlmpard, and wlmcomd as needed.

You can start the daemons in secure mode at boot time by editing the file

/etc/rc.config.d/wlm. You can also secure communications in wlmgui via the Preferences

menu.

For more information, see the wlmcert(1M), wlmd(1M), wlmpard(1M), and wlmcomd(1M)

man pages and the /etc/rc.config.d/wlm file.

• A WLM configuration is now host-based unless it includes a prm structure

WLM now assumes a configuration is intended for migrating CPUs between virtual

partitions or nPartitions unless the configuration includes a prm structure.

• New keywords for configurations without prm structures

The wlmd configuration file now supports the keywords hmincpu, hmaxcpu, and hweight.

Use these keywords when managing virtual partitions or nPartitions to specify minimum

and maximum CPU shares for a host as well as a CPU weight for the host. (These

keywords cannot be used in configuration files that include a prm structure.)

For more information, see the wlmconf(4) man page.

•The vpar and npar_icod structures in a wlmpard configuration are silently converted to

par structures
