SHMMAX = The maximum size(in bytes) of a single shared memory segment. SHMMIN = The minimum size(in bytes) of a single shared memory segment. The above settings let the max be bigger then we wil ever use and the min much smaller. They are sufficient for pretty much all systems. SHMMNI = The number of…
