Part of the reason many Oracle Customers do not use Oracle RAC
(Real App Cluster) is that RAC adds 50% PER CORE to the overall
license costs. At list $47,000 per core + annual support, that is
not a small consideration. 

It means the Oracle RAC cluster costs would increase to list
$70,000/per core * processor core factor.

Oracle Rdb Clustering is INCLUDED with the $47,000/core
licensing. Yes, it's still crazy pricing. 

Good news for VSI OpenVMS Customers using Rdb is that the Oracle
Rdb pricing *should* drop by 50% on OpenVMS X86-64 because the
X86-64 PCF is 0.5.

Btw - there was a presentation on SharkDB at the Bootcamp. It is
a native, high performance DB for OpenVMS that is 100% cluster
aware. Written to take advantage of OpenVMS native features for
max scalability.
