Configuring WLM
Notification of ‘Instant Capacity needed’ / Pay per use optimization
Chapter 5 145
WLM does not enable Instant Capacity or Pay per use (PPU) reserves. It
merely informs you that the reserves could help you meet your SLOs;
manually activate the reserves if you feel it is appropriate. (Independent
of this keyword though, you can use wlmpard to automate activation of
these reserves.)
To enable notification, use the icod_thresh_pri keyword in your WLM
configuration. This is a global keyword—it should be outside all prm, slo,
and tune structures. The syntax for icod_thresh_pri is:
icod_thresh_pri = integer;
where
icod_thresh_pri
Is an optional keyword. Specifying this keyword allows
you to use an EMS resource to notify you when
Instant Capacity reserves could help meet SLOs.
integer
Is an integer value greater than or equal to 1. If Instant
Capacity reserves exist, they are considered needed
whenever SLOs with a priority from 1 to integer are
failing. If an SLO with a priority in this range is failing,
notification that Instant Capacity reserves are needed
is sent using an EMS resource.
Notification is made through the following EMS resource:
/applications/wlm/icod_reserves_needed
When Instant Capacity reserves are not available or are not required,
the EMS resource is set to:
ICOD_NEEDED_FALSE (0)
