SHMMAX paramater in linux


Hi to all;

Shared memory - (shmall, shmmax, and shmmni)

SHMMAX :-

Can we set max value of the SHMMAX parameter is above 4GB.
if so ,

>> What is this formula >>
Quote:
On a 32-bit Linux operating system, without Physical Address Extension (PAE), the physical memory is divided into a 3GB user space and a 1GB kernel space. It is therefore possible to create a 2.7GB SGA, but you will need make several changes at the Linux operating system level by changing the mapped base. In the case of a 2.7GB SGA, you would want to set the SHMMAX parameter to 3GB.
