There are two methods to configure the Kernel parameters in RHEL

1. by using the command "sysctl -w <parameter_name>= <value>

The above command will change the kernel parameters on the fly but the changes are not persistent with system reboots. That is why people always choose the second method to make changes to kernel parameters

2. By editing the file "/etc/sysctl.conf" file

         A. Edit the file "/etc/sysctl.conf" by adding the parameters along with values
         B. execute "/sbin/sysctl -p" to make sure that the changes are made using the values inside the above mentioned file.

The advantage with the second method is that the changes are persistent with system reboots.

Hope that the information will be useful for you.
