Does /dev/shm reduce memory available for non-shared memory segments?
 
On a RHEL 4.8 Oracle server, I have provided /dev/shm with 7 GB of tmpfs, like so:
tmpfs /dev/shm tmpfs defaults,size=7g 0 0

The box has 8 GB of RAM total. Does this mean that all other processes have only 1 GB to use? Are they prevented from using any of the 7GB?

Thanks for any insight.
