Thanks Andrew
Yes one thing to be kept in mind is Oracle License that has to go against full
Physical Server
I am trying to see what are pros and cons of using VM vs physical server
especially for RAC. What kind of issue like IO etc been experienced and how to
troublshoot/experience for very high OLTP applications. There are around 250
Database on around 80-100 Physical servers. Some are Aix,Linux,Solaris and now
plan is to rearchitect to move them to Linux and hence plan is going to check
RAC or all non-RAC with VMWare to provide any added resilency.

{}#yiv3583482720 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. From: oracle-l-bounce@xxxxxxxxxxxxx

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.
