I'd love to know how many "databases" can be consolidated into one cluster IF
that cluster is running a single node RAC? Isn't that exactly and precisely the
same as moving schemas across instances?
And how is "high availability" any better in a single node RAC than in a single
instance database? And how do "rolling patch application as well as rolling
upgrades" work in a single node RAC?
Oh, it needs more than one node, doesn't it? So exactly what is the point of
all that "one node RAC" utter marketing nonsense?

That's fairly simple: it is easy to expand one node RAC into two node RAC
and three node RAC. Basically, it's a sales tool. If you already own one
node RAC, you are far more likely to expand it into a several node RAC
than if you just have an Oracle EE server without RAC.

The claim of course is that the customers demanded this "feature".

It certainly may have been demanded by Oracle partners who may be able
to sell the one node rac first then upsell to multi node rac later.

Why don't you setup a test environment and check it out?

Huh ?
Are you sure you can do rolling upgrades ?

I dont think so.
