Kernel Parameter Requirements - Linux Installation

To install and run the common components on Linux, the following kernel parameter

requirements must be met or exceeded:

msgmax = 32768

msgmnb = 65535

msgmni = 128

msgseg = 8192

semmni = 256

semmns = 512

semmsl = 100

shmmni = 512

shmmax = 1073741824

file-max = 8192

threads-max = 65262

To update the kernel parameter values

1. Issue the following commands depending on the kernel parameter values you want

to see:

Parameter

Command

msgmax, msgmnb, msgmni

/sbin/sysctl -a | grep msg

semmni, semmns, semmsl

/sbin/sysctl -a | grep sem

The results are similar to the following:

kernel.sem = <semmsl> <semmns>

shmmax, shmmni

/sbin/sysctl -a | grep shm

file-max

/sbin/sysctl -a | grep file-max

threads-max

/sbin/sysctl -a | grep threads-max

The current kernel parameter values are displayed.
