We are moving to Oracle 9.2 and I want to recommend to install 64-bit instead of 32-bit which we were using before. Ofcourse the question arises, what is the difference between Oracle 32-bit and Oracle 64-bit. We have HP-UX 11i 64 bit installed.
Solved! Go to Solution.

SolutionMajor difference would be more than a terabyte of addressable memory.
32-bit applications can only address 1.75Gb of memory - whereas 64 bit apps can address up into the Terabyte range.

Re: Difference between Oracle 32-bit and Oracle 64-bit
32 bit has memory limitations that make this large object pre-loading more difficult.
64 bit also allows for much larger shared memory which newer versions of oracle rely upon.

Re: Difference between Oracle 32-bit and Oracle 64-bit
I think now I have something to make my case for 64-bit Oracle.
Thanks

Re: Difference between Oracle 32-bit and Oracle 64-bit
Nevertheless, the client software can be either 32 or 64 bits. You just have to choose the right PATH for the libclntsh.sl

I would simply add:
A 64bit OS would allow us to address much more memory then a 32bit one. On a 32bit system (a system where pointers are 32bits) we can address 4gig or less of RAM. That limits the size of an SGA. On a 64bit system -- we can address an incredibly large SGA.
