It is not only the cpu count but also the core count and the relevant oracle multi core cpu licensing factor that counts.

For example a quad core intel or amd cpu counts as 2 ( 4 times .5 ) while a dual core cores as 1 cpu for licensing purpose varies based on hardware platform etc.

To get below a count of 4 on windows I think you have to have a machine that has less than 4 cpu's ( pull some of them out in other words or use a different box ).

Certain platforms and os combinations ( solaris for example ) allow you to partition the machine but it has to be a hard partition and not sure windows has any such "oracle validated" type of configs.

Look at the oracle licensing and multi core documents. Received on Sun Apr 20 2008 - 18:46:09 CDT
