HP-UX Workload Manager A.03.04.xx Release Notes

Temporary Instant Capacity (TiCAP) expires while WLM is managing
nPartitions
Issue
WLM manages nPartitions using its wlmpard daemon. Assume wlmpard is
started on a system that has Temporary Instant Capacity in use. If that temporary
capacity expires, wlmpard will still be able to deactivate cores without any
problems. However, wlmpard may attempt to activate cores based on the
expired capacity. These attempts will fail because the temporary capacity no
longer exists. wlmpard will not abort, but it may continue to attempt to activate
unavailable cores, generating a message of the following form in
/var/opt/wlm/msglog:
Error increasing core count on partition par_name (has x
needs y).
You will also see the message:
Unable to set the local partition to z cores. Check the
partition status.
where x, y, and z represent integer values.
Workaround
Add a utilitypri statement to your wlmpard configuration, say
configuration_file, and then load the new file:
# /opt/wlm/bin/wlmpard -a configuration_file
The utilitypri keyword allows WLM—when Temporary Instant Capacity
is available—to adjust the total cores to meet demand.
Specifying this priority ensures WLM maintains compliance with your
Temporary Instant Capacity usage rights. When your prepaid amount of
temporary capacity expires, WLM no longer attempts to use the temporary
resources.
NOTE: Beginning with WLM A.03.02, you can set a threshold that determines
when WLM will stop allocating temporary capacity resources. Prior to WLM
A.03.02, the threshold was fixed at 15 processing days (where WLM stops
allocating temporary capacity if 15 or fewer processing days of temporary
capacity remain available). For more information, see wlmparconf(4).
Automatic activation of Instant Capacity core without authorization
Issue An Instant Capacity (iCAP) core was automatically activated without customer
authorization.
Workaround Please contact your HP representative.
If you have Instant Capacity or Pay per use (PPU) software installed, either:
• Do not use WLM virtual partition management, or
• Use vPars version A.03.01 or later
Partition management affected when cores are deactivated with iCAP on
fully owned system
Issue Instant Capacity versions 8 and later enable you to deactivate cores on fully
owned systems. However, using this feature prevents WLM from managing
partitions on those systems.
To determine whether a system is running in this state, run icapstatus -M:
