And why would you want to set that parameter? Your RDBMS has the 6th sense and will sense the platform it is running on. If the hyperthreading is enabled, Oracle will sense each thread as a separate CPU. I am not sure about the super-duper Nehalem CPU which has a special kind of hyperthreading because I don't have the machine available.Received on Fri Sep 04 2009 - 14:11:35 CDT
