RE: RAC Geographical Architecture

Of course, one thing to note here is that there is not a separate product 
called RAC Extended Cluster.  This is simply an implementation of RAC across a 
set of nodes that can be some distance from each other, where "some distance" 
is defined by the operating system capability of clustering nodes.  Depending 
on the OS, this may be known under various names like campus cluster and so on.

And one more thing to note - I see this offered up sometimes as a complete HA 
solution.  RAC, by itself, is to me not a complete HA solution until you add 
something like DataGuard as well.  But that's another discussion altogether.  :)
