Oracle Linux Friday Spotlight - January 10, 2014

Happy Friday!

Our spotlight this week is on a great technical article over at Oracle Technology Network written by Oracle's Christopher Jones titled "How to Set Up DTrace to Detect PHP Scripting Problems on Oracle Linux."

The Unbreakable Enterprise Kernel release 3 (UEK) provides built-in support for DTrace. This can help you track down performance problems with your applications or scripts. In this article, Christopher walks through how to enable DTrace for the popular scripting language PHP on Oracle Linux and goes into some detail to how it works, including a simple D script to get information out of a sample PHP script.

This is a really fantastic article, so if you're interested in using DTrace to tune your PHP scrips, give it a read through.

We'll see you next week!
