Configuring WLM
Notification of ‘Instant Capacity needed’ / Pay per use optimization
Chapter 5146
When Instant Capacity reserves exist and are needed, the EMS resource
is set to:
ICOD_NEEDED_TRUE (1)
In this case, it may be possible to reduce SLO failures by activating some
Instant Capacity reserves.
When using icod_thresh_pri, you can also use
icod_filter_intervals, another global keyword that must be outside
all prm, slo, and tune structures. The syntax is:
icod_filter_intervals = integer;
where
icod_filter_intervals
Is an optional keyword. It allows you to ignore
short-term fluctuations in the conditions that affect the
EMS resource.
integer
Is an integer value greater than or equal to 1. This
value indicates the number of consecutive WLM
intervals over which Instant Capacity reserves must be
needed before the EMS resource is changed to
ICOD_NEEDED_TRUE. Similarly, it is the number of
intervals over which Instant Capacity reserves are not
required before the EMS resource is changed to
ICOD_NEEDED_FALSE.
