So if its a memory, CPU issue, it will scale.... Cool!!! Thank you makes a little more sense now
The focus of Oracle RAC is high availability 🙂
You can always add CPUs and Memory whitout the need of adding a new node.

Hmmm.... isn't that the "definition" of virtualized machines?

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Not necessarily. You can run Oracle RAC on top of either physical or virtual machines but, since Oracle is licensed by physical CPUs you may want to double-check the licensing cost before going for a virtual environment.
