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

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.
