You may want to test your software application
for proper operation and improved performance by activating an additional
core. The use of temporary capacity (TiCAP) or Instant Access Capacity
(IAC) is required for activation of a core without usage rights for
testing purposes. See Chapter 5: “Temporary Instant Capacity” for details.
The following testing guidelines are meant to
be an aid to your test plan. You may need to get consulting help to
develop a detailed test plan.
Test your applications
for proper functionality and performance first by testing with the
number of inactive cores equal to the number of cores without usage
rights. (The system should already be configured this way.) Be sure
to check measurement tools that monitor core usage.
Acquire temporary capacity
for the necessary amount of core test activation.
Use temporary capacity
to activate one or more inactive cores to be used while your applications
are running.
Confirm that measurement
tools, which monitor processing usage, account for the newly activated
cores.
Verify that applications
are benefiting from the performance of the extra cores (as per your
expectations for your applications). Note: some applications may need
to be restarted or reconfigured to take advantage of the newly activated
cores.
When you are finished
with your testing, deactivate cores until the number of inactive cores
again matches the number of cores without usage rights, thereby stopping
the usage of temporary capacity.
Use icapstatus to verify that no cores are consuming temporary capacity.
