HP-UX Workload Manager A.03.01 Release Notes for HP-UX 11i v1 and HP-UX 11i v2

HP-UX Workload Manager Release Notes

Compatibility information and installation requirements

Disk and memory requirements

This version of WLM requires:

• 16 Mbytes of disk space in /opt/wlm/

• disk space in /opt/prm/:

8 Mbytes

• 5 Mbytes of memory (Also, your system must have at least 100 Mbytes of available

memory for WLM to properly manage the workloads’ memory usage. If extended_shares

is enabled, WLM memory control requires at least 512 MB of memory.)

Network operating environment

WLM’s network interfaces are designed to operate correctly and defend against attacks in a

moderate to high threat environment, such as a DMZ. You may use network protections such

as firewalls to provide an additional level of defense and to give you additional time to react in

the event that a security loophole is found.

NOTE As of A.03.01, WLM enables secure communications by default when you start

WLM using the /sbin/init.d/wlm script. You should ensure that the secure mode

variables are enabled in /etc/rc.config.d/wlm. You also must distribute security

certificates to all systems or partitions being managed by the same WLM global

arbiter (wlmpard). For more information on using security certificates and other

tasks necessary to enable secure communications, refer to the wlmcert(1M)

manpage.

The WLM wlmpard and wlmcomd daemons use the following port numbers by default:

wlmpard 9691

wlmcomd 9692

Make sure these ports are kept open. To change these port numbers, refer to the wlmpard(1M)

and wlmcomd(1M) manpages.
