64 bit or 32 bit

Hi Fabrizio:
Thank you for your reply. For option 2 you also mean EM64T Xeon
processors and not just AMD64 right?
Also when you say AMD64, which Opteron model are you using? 200 or
250? Please inform. I need to make a hardware decision as well for
running Oracle 10g.
Thanks,
Yasaswi

Well, my reply was imprecise.
As Jeroen stated there is even oracle10g for z/linux. I mised it since I
have never tried that architecture. Unfortunately I cannot install linux
on my company mainframe

However the option 2 referred to EM64T and AMD64 but I have first hand
experience only with the second (HP DL585 Model 848, 4 CPU 2.2GHz/ 1MB).
The machine is execellent. Maybe the fastest I tested (IBM power5 should
be even faster... maybe in 6 months I'll have something mounting them).

I believe the opteron (SMP configuration) could be a good solution even
if you don't need 64bit...
