Re: 32bit vs 64 bit Linux for Oracle (was: Hardware recommendations for RedHat X86-64/10gR2)

We have run Oracle database in 64-bit mode on all our Unix platforms. With linux we opted for 32-bit few years back. I believe this was so because the fixes were available much faster in 32-bit than in 64-bit, so the support was better off dealing with 32-bit then.

Now we are geared to move to 64-bit hardware and OS. We want to avail all advantages that may not be possible in 32-bit.

Thanks!
