Firstof all sorry for posting linux kernel question in pgsql-general, but i am trying to figure out what value to set for postgresql db server.
RAM = 16GB, what value should i set for shmall? If i set shmall to 4294967296 (4GB), current PAGE_SIZE is 4096 should i need to set my shmmax = 4294967296*4096 = 17592186044416? cat /proc/sys/kernel/shmall 4294967296 getconf PAGE_SIZE 4096 Current Shmmax - ==> cat /proc/sys/kernel/shmmax 68719476736 should i need to increase my shmmax to 17592186044416? also what value should i need to set shmall? what happens if i set shmmax to lower than the expected size? Thanks Deepak
