Software Application Considerations
Some software applications size themselves based on the number of
available processors when the application is started. If an application is
running when an additional processor is activated, it may not recognize
the newly activated processor as an available processor. Therefore, it
may be necessary 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 processors
• Reconfigure the application, prior to it being restarted, for maximum
performance benefits of the newly activated processor
• Use the deferred activation option when activating processors so that
processors are only activated in conjunction with system reboots - see
the manpage icod_modify(1M) for details
IMPORTANT When you activate a processor, the number of active processors in the
system increases. Consequently this may require a license upgrade for
some of the software on your system. A license may be required for
software from other application providers.
