HP Instant Capacity User's Guide for Versions 8.x

Test Activation of Cores Using Temporary Capacity
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” (page 73) 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.
1. 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.
2. Acquire temporary capacity for the necessary amount of core test activation.
3. Use temporary capacity to activate one or more inactive cores to be used while your
applications are running.
4. Confirm that measurement tools, which monitor processing usage, account for the newly
activated cores.
5. 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.
6. 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.
7. Use icapstatus to verify that no cores are consuming temporary capacity.
