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

0 votes

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?

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
