Oracle Enterprise Edition Licensing - Core metrics

Question

Oracle: 10G (10.2.0.4) 64-bit, Enterprise Edition
Running on Xeon Intel chips, of which I believe have a core factor multiple of 0.5
We have 540 NUP licenses on our site. We obviously have a Live box, and a few test boxes.
One of our test boxes has 4 cores (Intel Xeon chip). Using the minimum usage licensing for Enterprise Edition, after the core factor of 0.5 is applied we would count 2 cores, I believe we would need 25 NUP licenses per core, which would = 50 NUP minimum for this test box.
Is this correct??
My concern is that there may be a minimum of 4 cores (after factor) for Enterprise Edition. I cannot find anything that confirms this. I can only find maximums for Standard Edition, nothing for Enterprise Edition.
If there is a minimum of 4 cores, then I need to pull out one of these test boxes.
Anyone knows the facts on this?
Many thanks.

Answer 1

Again like everybody said above, you should contact Oracle Sales Rep.
But Still let me answer your question, There is noting like minimum of 4 cores for enterprise edition. You can have NUP license even on 1 CPU.
Another thing which might benefit you that, Oraclel gives you Limited Use Enterprise Licenses for your Test/Dev boxex which means You only need minimum of enterprise 10 NUP's for Test/Dev instead of minimum of 25. This will save you 15 NUP's per processor. But for this you have to talk to Oracle or any third party vendor.
But again best bet is o talk to Sales Rep.
