Disk and memory requirements
WLM A.03.04 requires:
• 16 Mbytes of disk space in /opt/wlm/
• 9 Mbytes of disk space in /opt/prm/
• 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 available memory. Available memory is
the amount reported by prmavail; it is the amount that is not reserved for the kernel
(/stand/vmunix) and its data structures and for nonkernel system processes. Thus, available
memory is not the total memory on the system. Available memory varies over time. For more
information, see the Process Resource Manager User’s Guide.)
Network operating environment
WLM 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, see wlmcert(1M).
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, see wlmpard(1M) and
wlmcomd(1M).
