Infrastructure Software

Hi all,

I've read a few documents about Oracle licensing :
http://www.sun.com/third-party/global/oracle/consolidation/Containers_Oracle_041305.pdf
http://www.oracle.com/corporate/pricing/partitioning.pdf

However, there's one thing not clear to me. In Solaris zones, you dedicate threads (usually referred to as 'CPU' on Solaris) to zones. Oracle licensing is always about the number of cores used by the partition, not the number of threads. How do you convert from threads to cores?

I'll give an example:
A T2 system with 2 processors, 8 cores each, 8 threads each (128 threads in total). You create a resource pool with 2 CPUs (threads): 1 thread from one core, and 1 thread from another one (or they are assigned like that for you) and associate a zone that runs Oracle.

I can think of two ways of calculating the number of cores used:
1) divide the number of dedicated threads by the number of threads per core: 2 / 8 = 0.25 (optionally round it up to 1) -- This is how IBM does its licensing.
2) count the number of physical cores that are being used by the zone. In this case this is 2, as the threads are not running on the same core.

Can anyone help me figuring this out?

Thanks!

Regards,
Mathieu
