We were evaluating this for a ct (in NZ, Oz) and they were looking at having
to license every core (or CPU) in the VM cluster that Oracle runs in ,
leading to the conclusion that Oracle would need it's own VM cluster(s) for
licensing reasons, rather than sharing a cluster with all the app/web
servers and other rif-raf ;)
