How to get bigger contiguous shared memory

With 32 bit program, we can have max of 1.75/2.75 shared memory.
Now one of my application (single process) needs contiguous shared memory(mmap) larger than 1 GB, how should i achive this ? and also anyone has idea how Oracle manages to get shared memory greater than 2.75 GB ?

Thanks

Either use memory windows software for virtualizing shared memory needs of your applications or migrate to 64-bit.

Hi RAC,
My understanding of memory window is,"Process should be in same memory window to share the data", and memory window is restricted to 1 GB, so how can i achive this ?

Thanks
