• Configuration Wizard supports more WLM configuration options
• PSET-based workload groups with no active SLOs have their CPU count reduced to
zero
• cpushares keyword supports an offset
• To support nPars in addition to vPars:
— wlminfo's vpar command has change to par
— wlmpard's -l vpar is now -l par
•New cntl_smooth keyword allows you to get a running average of a metric from a
data collector, smoothing out dips and spikes in the metric before it is used by WLM
• perl is expected to be in /opt/perl/bin/
• New variables in /etc/rc.config.d/wlm file to support new communications
daemon, wlmcomd
• New example configurations for transient groups and for vPar and nPar
management in /opt/wlm/examples/wlmconf
• Passive mode now supports auditing
• You can now use WLM's vPar management on systems with iCOD software installed
if you are using vPars version A.03.01 or later
Impact
WLM A.02.02 includes the following impacts:
• Enhanced Wizard and new GUI simplify configuring WLM
• nPar resizing opens new possibilities in partition management
• PSET-based groups with no active SLOs now get 0 CPUs, allowing CPUs to be used
elsewhere
• With new cntl_smooth keyword, you are advised to transition away from the
smooth and expsmooth utilities
• WLM scripts that use perl now require perl to be in /opt/perl/bin/ instead of
/usr/contrib/bin/
• If you have modified /etc/rc.config.d/wlm, you should merge the new file
(/opt/wlm/newconfig/etc/rc.config.d/wlm) with your /etc/rc.config.d/wlm
file

Performance
Performance is improved when WLM is used properly, but can degrade when WLM is not
configured appropriately.
