I have done this several times. It is pretty much identical to a physical
setup. I have never run into any real problems. There are quite a few
low-level pieces that need to be set up, for example setting the multi-writer
flag on the shared storage, turning on node affinity, etc. But we have done it
quite often and had very good results.
Our performance tests generally show performance to be just as good as a
physical server, but with the added resiliency of VMware.
There are a few gotchas that you need to watch for, eg. One time we had a
machine do an unplanned storage VMotion, and it copied the shared disks. That
was a really freaky thing to look at.
You will have to license the entire physical machine that it runs on, and make
sure you use hardware affinity so that the VM does not run on a physical server
you do not plan to license.

Subject: Oracle RAC/non-RAC on Vmware vs Physical Server
Hi Experts
Can someone please share your experience with facts on using Oracle 11g/12c
RAC/non-RAC on Vmware based VM using Linux ? Need to create the doc to show the
pros and cons of the environment for consolidation project. I am sure many have
either created/worked on such project and really appreciate your comments.
TIA
Sanjay
