I'm not sure why Oracle recommends such in their docs, as such changes aren't persistent through a reboot.

The sysctl command which is used to process /etc/sysctl.conf does essentially the same thing as "echo somevalue > /proc/sys/...", so from a functional standpoint it's the same operation, but with sysctl you get the benefit of not having to worry about your changes disappearing after a reboot.

You would think that with 'official' support for Oracle on RedHat, the docs would recommend setting values in /etc/sysctl.conf, instead.
