I would like to know if i need to disable cores on 5-7 or E-5 serries CPUs, (10 cores ) , since some of apps are licensed based on cores such as oracle. is there any way we can disable cores and will the OS will show the activated cores only ? and Oracle will be licensed only for activated cores?

If it's like Microsoft's system, I think it will only work with as many cores you have a license for. But I'm not certain on that, you might need to contact Oracle to find out. To disable cores in the OS (Win 7 process, might work with Server), open Configuration Manager (msconfig) > Boot > Advanced options > check Number of processors and use the dropdown to select the desired number.

Being that this software is licensed by CPU cores you will need to disable the additional cores in the BIOS. Anything related to how the software will work based on cores will need to be address by your vendor or sales rep because this is not the right place for that sort of question.

Thanks Leo, for neieus, let me rephrase my question again, now regardless of OS or app, if I need to disable some cores from a 10cores CPU (I am talking about pure HW) is it possible that we can do it in server with E-7 or E-5 series CPUs. and when I will install OS. MS or RHL or any hyper viser, the HW will show them ONLY activated Cores...

Leo has answered but its limited to Win7, where as I am asking about win datacenter addition or RHEL. or hypervisers like VMware.

Which version of Data Center Edition are you referring to? I currently have Windows Server 2012 R2 Data Center running on a VM right now and using the same steps to access BOOT Advanced options are the same as they are for Win 7 to select the amount of cores.

It really is up to you, but you definitely should talk to your reseller or Oracle to avoid costly licensing mistakes. Buying less powerful servers dedicated to Oracle could be the least expensive solution.

It's doable, but is it an acceptable solution to Oracle?

That's True dear.. but customer has already bought the machines with 2 CPUs and each CPU is 10 cores, and now they wanted to have it running oracle, so I needed to show them a little value add that they can still install oracle over these CPUs and they can reduce their cost by DEACTIVATING some of the available cores and machine will show them .. lets say six cores available. i

That's true.. thank for your help dear.. will check with oracle, and even with SQL. since they both do licensing on core based. and if they don't have issue. it will be a breakthrough, and customers can do upgrades on demand ( putting additional licenses on existing servers and no need to buy additional HW but just activate cores.
