Thanks Freek - good clarification of the issue.
Based on what I've read online - Oracle is not always consistent on that
(probably a lack of knowledge even by the sales reps on the differences between
hyperthreading and multi-cores. I was under the impression that if the OS
showed a certain count of cpus you had to use that number and multiply it by
the factor but clearly I'm one of the ones in the "confused" boat. :)

Hi,
The cpu threads are not playing a role when determining the number of processor
licenses.
Only the number of cores and processor type is important (for Enterprise
Edition).
You can find this in the processor definition (should be in the end user
agreement)
extract:
"The number of required licenses shall be determined by multiplying the total
number of cores of the processor by a core processor licensing factor specified
on the Oracle Processor Core Factor Table which can be accessed at
http://oracle.com/contracts";
so 2 intel x86-64 quad cores with hyperthreading will show 16 os cpu's, but
count for 8 cores and require 4 processor licenses.
A general remark:
Whenever you have a question on oracle licensing, don't (solely) trust on
sources such as mailing lists (no, not even on me), but ask the question to
your Oracle account manager and let him/her confirm in writing.
The amount of money involved when you get it wrong (either by buying to much of
by getting penalties after a license audit) it way to high. ;-)
