4.12 Software Application Considerations
Some software applications size themselves based on the number of available cores when the
application is started. If an application is running when an additional core is activated, the
application might not recognize the newly activated core as available for processing. Therefore,
you might need to do one of the following for optimal performance with this type of application:
• Restart the application in order for it to recognize the presence of newly activated cores.
• Reconfigure the application prior to restarting it, for maximum performance benefits of the
newly activated core.
• Use the deferred activation option when activating cores so that processors are activated
only in conjunction with system reboots. For details, see icapmodify(1M) for details
IMPORTANT: When you activate a core, the number of active cores in the system increases.
Consequently, a license upgrade might be required for some of the software from HP or other
vendors on your system.
