Software Application Considerations
Some software applications size themselves based on the number of
available processors when the application is started. 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
• use the offline activation method when activating processors - see
“Understanding Online vs. Offline Activation Methods” on page 66
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
HP-UX, HP-supplied software, or software from other application
providers.
