Hi,
Thanks for your answer but I'm not talking about cores, but the whole processor. Oracle says that you have to license every processor where Oracle is installed and/or running. I mean, what if I have a processor disabled from the BIOS or even if it is not present in the server and the socket is empty (I'm really interested in knowing what happens if it is disabled).
As I understand it, I'm not talking about partitioning here as I will not use the disabled CPU (not only the CPU Core) to "install and/or run" any Oracle or any other application.
So let me do the question again:
Can I disable physical processors (not talking about CPU cores but the whole chipset mounted on the socket) from BIOS in order to avoid having to license them with Oracle?
Case scenario:
1 Cisco Server (or any brand not being Sun)
4 Sockets
4 Physical Procesors single core
2 Physical Processors enabled in BIOS and the 2 other disabled
Should I have to consider 4 or 2 of the physical processors towards licensing?
Thanks in advance
