Blog: How to Get Started Using DTrace on Oracle Linux DTrace is now available on Oracle Linux. Here are several resources to help you become familiar with it, including a video
interview in which its inventor explains why sysadmins should be using it to improve the performance of applications they
have deployed, download instructions, a how-to article to get you started, links to one-liners and other resources. Plus a
few bonus features. posted Wed, 12 Jun 2013 11:17:00 +0000
Tech Article: Using DTrace on Oracle Linux DTrace is a powerful tool, and it can do some amazing things. But it's not that difficult to get started doing simple things.
You can build up from there. In this article, Richard Friedman gives you a high-level overview of DTrace and its major components:providers,
modules, functions, and probes. He explains how you can use either one-liner commands on the command line, or write more complex
instructions in scripts, using the D language. He provides simple examples for each. It's a great way to get your feet wet. posted Fri, 07 Jun 2013 16:30:12 +0000
Blog: How the Oracle Linux Update Channels Are Structured Every Oracle Linux distribution release is freely available as ISO installation images from the Oracle Software Delivery Cloud.

Tech Article: Preventing Silent Data Corruption in Oracle Linux Linux, like any OS, is vulnerable to silent data corruption. It can be caused by a faulty component or sysadmin error. It's
nearly impossible to detect. But it's not impossible to prevent. EMC, Emulex, and Oracle partnered up on an end-to-end solution. posted Thu, 21 Feb 2013 21:22:10 +0000
Blog: How to Treat an NFS File As a Block Storage Device More about the dm-nfs kernel module, courtesy of Lenz Grimmer. If you want to work with block-based shared storage devices
such as ocfs2, but you don't have iSCSI or SAN storage, you can use NFS, instead. Just create an NFS file that will contain
the block-based shared storage device. In fact, you can create several shared storage devices that way. And use the "dm nfs"
utility to create a device map. Lenz Grimmer expands on Wim's original blog. posted Wed, 09 Jan 2013 16:39:22 +0000
