Configure kernel parameters at runtime
Modify the behavior of the Red Hat Enterprise Linux kernel at runtime by using the sysctl command and by modifying configuration files in the /etc/sysctl.d/ and /proc/sys/ directories.
Configuring kernel parameters on a production system requires careful planning. Unplanned changes can render the kernel unstable, requiring a system reboot. Verify that you are using valid options before changing any kernel values.
