I have a question concerning 32 and 64 bit Oracle databases.
We have a HP-UX 11.00 64bit, running Oracle 8.1.7 (32bit) and Oracle 9i (64bit). The 32 bit is limited to a max of 1,75Gb ram. The box has 2Gb. If there is a memoryproblem in the future, would it be usefull to add more ram? In other words, will the 64bit application use it? And would it have any consequenses for the 32bit application?
Solved! Go to Solution.

Re: Oracle 8.1.7 32b and 9i 64b
Your system is a shared mulit-user system, so Oracle is never going to get all of the physical memory on a 2 G system.
If you double the memory, you'll increase resources for other non-oracle stuff, like writing to disks and such, improving performance.
If you add memory, the 64 Bit and 32 bit application will benefit.
I'd take a careful look at init.ora and make sure your resource allocation, SGA and all is realistic.

Re: Oracle 8.1.7 32b and 9i 64b
- 64 bits will be able to using this RAM as the addresses used by 64 bits applications are not the same as for 32 bits applications.
(and oracle 32 bits limit will stay the same)
- If you have any application using private memory, it could use more that 1.75 Gb even with 32 bits.
So as everybody already explained it will reduce your swapping and increase your performance.

Oracle provided ability to build a 32-bit Oracle application on 64 bit OS.
so if 8.1.7 is running fine, there wouldn't be no problem with 9i
