New article on OTN: How I Used CGroups to Manage System Resources In Oracle Linux 6

We just published a new article on OTN: How I Used Cgroups to Manage System Resource in Oracle Linux 6 by Ginny Henningsen.

In this article, Ginny explains how to use the Linux kernel's built-in resource control mechanisms (called "Cgroups") to manage the allocation of CPUs and memory to processes and how to configure disk I/O throttling for certain groups of processes. Cgroups is a very powerful and flexible feature of the Linux kernel. We hope you will find this article useful!
