Oracle's cpu_count parameter is same of no of cpu's shown in Windows task manager. I have seen 2 dual core chips on the server which show up as 4 cpu's in task manager and cpu_count to 4. I know, Oracle has licenecsing for multi-core chips, hperhreading etc, but my question is if I reduce cpu_count init.ora, will it effect Oracle licensing. I guess I have to ask my Oracle account manager. Received on Sun Apr 20 2008 - 20:15:27 CDT
