But the kernel on a 32 bit system addresses the first 4gb only. Windows has
awe and pae ux doesn't. I bet your jserv proccesses are paging.
Noup. It is limitation for single process. It doen't apply for whole system.
Kernel have it own part to work with, but it is just fraktion of
overall memory size in yuor system.

I may be wrong but that was my understanding from oracle.

I would try disagree with this option ;)
32 platform means that processes execute on that platform are limited
to addressing not more then 4GB of memory.
But at the same time you can have multiple processes which utilize 1-2 GB
each.
For Apps 11i typically you can configure multiple Jserv processes with
max Mem utilization to 1GB.
Let say if you configure 16 Jserv instances, then total RAM
utilization might be up to 16+ GB.
I would say 5MB for Form process and 10MB for each connected
Self-Service user might be good starting estimation ;)
PS I have seen some documents where Oracle stated that in terms of CPU
you can plan 50 users per single CPU. Form that time CPU speed
increased several times and I would say 200 users per CPU may be good
beginning figure.
Just my 0.02$,
