EBS on VM

[satish]

Hi Erman,

Need your help.

We have a physical server with 20 cores. Installed VMware and Created 2 vm each with 4 core cpu.  If we install oracle ebs on these 2 vms, one for db and for app, how does oracle consider the cores.
Is it 8 cores or 20 cores?

Pls share your experience.

Thanks,
SGU

Oracle considers VMware a soft partitioning technology. This means that, according to Oracle's licensing policies, simply limiting the number of vCPUs assigned to a VM on VMware does not restrict your licensing obligation to those virtual cores.

Therefore, for your scenario: Oracle will consider the cores to be 20 cores.

Use Oracle Linux KVM (with CPU pinning) instead.

Thanks for the update erman.

We are planning to migrate oracle ebs from physical servers to vm. Will that work? Can you share any pros and cons.

Thank you.

Yes. It will work.

As long as you configured your vm environment properly, (in terms performance, fault tolerancy etc) and according to your licenses no big cons. As long as your vm hypervisor and server is certified with Oracle (vmware is certified bytheway), it is safe. Just standard vm vs pyshical pros and cons. The world goes towards virutalization and dockerization, so no big cons.
Just watch out for the waits that may be introduced due to emulations (cpu and IO perf).
Vm related things are important, like VM - Oracle - Storage I/O alignment.. Stuff like that. your vm admin and your vm vendor (documentation) will help you on these things.
