What’s in this version

WLMTK Version A.01.06 provides the toolkits ApacheTK, DMTK, ODBTK, PPUTK, SASTK,

SNMPTK, and WebLogicTK. The new functionality of the individual toolkits is described

below.

• PPUTK’s utilitydc has been modiﬁed as indicated below:

— -f

This option was previously for specifying the number of consecutive WLM intervals

over which an EMS resource must be the same value before utilitydc activated a

processor.

Starting with this release, the -f option is for specifying the number of WLM

intervals that must pass between changes in the active CPU count. For example, with

-f 4, every time utilitydc makes a change to the active CPU count, it will wait at

least 4 WLM intervals before making another change.

— -u

Previously, this option allowed you to specify the deactivation algorithm that

utilitydc uses.

Starting with this release, the algorithm you specify with -u is used to determine both

when to activate and deactivate processors.

— -t

Previously, this option allowed you to specify a tuning value for the deactivation

algorithm that utilitydc uses.

Starting with this release, the tuning value is used in both activation and

deactivation.

— How utilitydc works

Assuming the number of WLM intervals speciﬁed using -f have passed since the last

change in the active CPU count, utilitydc checks the active CPU count and

determines whether the count should be changed again. utilitydc adds a processor

only if the EMS resource /applications/wlm/icod_reserves_needed is true. The EMS

resource is not checked before deactivating a processor.
