How can i change the value of proc sys kernel shmmax in a container

Question

When I run this command in my root directory-

cat /proc/sys/kernel/shmmax

It returns me improper value and that is the reason I am not able to complete my oracle installation and the pre-requisite verification fails.

Could you please let me know how to change the value and set it to the default value of shmmax?

Answer 1

Please follow the below command and set the value of shmmax to its default value

Make sure you execute in your root directory:

# echo "kernel.shmmax=2147483648" >> /etc/sysctl.conf
# sysctl -w kernel.shmmax=2147483648
kernel.shmmax = 2147483648
