Oracle9i on 32-bit solaris can't use more then 2GB RAM?

[zoza]

Hi all,
we have solaris running in 32-bit mode, and we want to upgrade oracle8i to 9i and also to add additional 2GB of memory. Now that mashine has 2GB, so it should be 4GB!
But, we heard that oracle on 32-bit solaris can only use up to 2GB!!!
Is that true? did anyone had that problem before? is there any work-around?
Any ideas?
Thanks
Tanja

32-bit solaris can use 4 gig of RAM just fine. The actual address register is 36 bit I tried to remain child-like, all I acheived was childish.

The shared memory area is limited to 4GB, perhaps that is the limit you have heard of? Annihilannic.

Thanks for your answers!
I still have some questions: is the 4GB 'shared memory area' solaris shared memory limit? or oracle SGA limit?
And if it solaris limit, then how much of it can oracle use (we wanted to give 3 or 3.5 GB to oracle, which seems to be impossible)? For oracle i read that it can use up to 2GB... Do you have any experience with that?
Thanks again!
