Hi Bart,
> Is it necessary that the hardware of all nodes is identical? No. You can use
different makes (Dell, HP, IBM, ...) in your RAC.
You just need to have the same architecture (32 or 64 bits) and the same OS.
And the different compouters can have more or less CPUs and RAM.
Don't forget that with RAC, you can decide to dedicate one of your nodes to
run heavy jobs and the remaining to serve your connected users. And depending
on the load you need to support on each computer, you can add more or less CPUs
and RAM.
> Can I have several versions of Oracle on one RAC?
NO. All the instances of the same RAC database must be of the same version of
Oracle.
But, you can run different versions of Oracle RAC on one computer.
Regards,
Jean-Hilaire

Hello,
I have some RAC questions :
Is it necessary that the hardware of all nodes is identical? For the OS it is
clear, but for the machines I'm not certain? Can I for example have two nodes
with each 2 cpu's and a third node with 4 cpu's?
Can I have several versions of Oracle on one RAC?
Regards,
Bart
