Friday Spotlight: COLLABORATE14

Happy Friday!

If you’re an Oracle customer, you’re probably familiar with the yearly COLLABORATE conference put on by the IOUG, OAUG, and Quest user groups. It’s a fantastic conference where lots of real world Oracle use cases are discussed, and this year's show is happening next week in Las Vegas.

If you’re going to the show, be sure to check out the Oracle Linux and Oracle VM content there. First, there is an Oracle Linux / Oracle VM booth in the demo area, where you can talk to some knowledgable folks. If you have questions on using Oracle Linux or Oracle VM in your environment, this is the place to go!

Second, there are two sessions that will be very interesting for you:

998: Oracle Linux—State of the Penguin 
Date: Tuesday, April 8
Time: 4:15 PM
Location: Level 3, San Polo 3501A

997: Oracle Virtualization Strategy and Roadmap
Date: Tuesday, April 8
Time: 5:30 PM
Location: Level 3, San Polo 3501A 

Also, there are several sessions related to Oracle Linux and Oracle VM that aren’t being done by our team, but would still be valuable for you. In the agenda tool, search for “Linux", "Oracle Linux", “Virtualization", and "Oracle VM”.

If you’re going to the show, we hope to see you there!

Friday Spotlight: Tips for Hardening an Oracle Linux Server

Happy Friday!

One of the things I like about our Friday Spotlight is not only do we talk about new things, it also gives us an opportunity to highlight older material that is still valuable. That's the case with this week's spotlight, which is about an article from 2012 that covers tips for hardening an Oracle Linux server. If you've come to Oracle Linux in the last couple of years, you might not have seen this, and it's just as a relevant today as it was then.

This in-depth article covers minimizing active services, locking down network services, managing users and authentication, and much more. If you're a Linux administrator, you might want to consider adding this article to your Reading List, saving to Pocket or Evernote, or whatever mechanism you use to hold on to good resources.

Friday Spotlight: Frequently Asked Questions about Oracle Linux

It is Friday and that means it is time for our Spotlight! 

Our spotlight today is the recently updated Oracle Linux FAQ. This is an excellent document that features some of the questions that everyone asks about Oracle Linux and Oracle Linux support. We cover variety of topics including general definitions, compatibility, support, pricing, indemnification, migration and many more.. 

Here's one of the questions as an example:

Q: What is DTrace for Oracle Linux?

A: DTrace is a comprehensive dynamic tracing framework that was initially developed for the Oracle Solaris operating system, and is now available to Oracle Linux customers. DTrace is designed to give operational insights that allow users to tune and troubleshoot the operating system. DTrace provides Oracle Linux developers with a tool to analyze performance, and increase observability into the systems they own to see how they work. DTrace enables higher quality applications development, reduced downtime, lower cost, and greater utilization of existing resources. It is available to download from ULN for Oracle Linux Support customers. 

Read more in the newly published FAQ.

Have a great weekend!

Friday Spotlight: Ksplice SNMP Plugin

Happy Friday!

Over at our Ksplice Blog (which has one of my favorite taglines, "Rebooting is Obsolete"), Oracle's Tim Hill writes about the new SNMP plug-in for Ksplice, which allows the use of Oracle Enterprise Manager or other SNMP-compatible monitoring solution to monitor Ksplice instances. It's very cool stuff, we hope you check it out.

We'll see you next week!

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!

Oracle Linux: Free as in Speech AND Free as in Beer

One of the biggest benefits of Oracle Linux is that binaries, patches, errata, and source are always free. Even if you don’t have a support subscription, you can download and run exactly the same enterprise-grade distribution that is deployed in production by thousands of customers around the world. You can receive binaries and errata reliably and on schedule, and take advantage of the thousands of hours Oracle spends testing Oracle Linux every day. And, of course, Oracle Linux is completely compatible with Red Hat Enterprise Linux, so switching to Oracle Linux is easy.

CentOS is another Linux distribution that offers free binaries with Red Hat compatibility. Traditionally, CentOS has been used for Linux systems which do not require support in order to reduce or avoid expensive Red Hat Enterprise Linux subscription costs. Recently, Red Hat announced it was “joining forces” with the CentOS project, hiring many the key CentOS developers, and “building a new CentOS.” This is a curious development given that the primary factors that have made CentOS popular are that it is free and Red Hat compatible.

It would be natural for existing CentOS users to wonder what Red Hat actually has in mind for the “new CentOS” when the FAQ accompanying the announcement states that Red Hat does not recommend CentOS for production deployment, is not recommending mixed CentOS and Red Hat Enterprise Linux deployments, will not support JBoss and other products on CentOS, and is not including CentOS in Red Hat’s developer offerings designed to create “applications for deployment into production environments.”

If Red Hat truly wished to satisfy the key requirements of most CentOS users, they would take a much simpler step: they would make Red Hat Enterprise Linux binaries, patches, and errata available for free download – just like Oracle already does.

Fortunately, no matter what future CentOS faces in Red Hat’s hands, Oracle Linux offers all users a single distribution for development, testing, and deployment, for free or with a paid support subscription. Oracle does not require customers to buy a subscription for every server running Oracle Linux (or any server running Oracle Linux). If a customer wants to pay for support for production systems only, that’s the customer's choice. The Oracle model is simple, economical, and well suited to environments with rapidly changing needs.

Oracle is focused on providing what we have since day one – a fast, reliable Linux distribution that is completely compatible with Red Hat Enterprise Linux, coupled with enterprise class support, indemnity, and flexible support policies. If you are CentOS user, or a Red Hat user, why not download and try Oracle Linux today? You have nothing to lose – after all, it’s free!

Oracle Linux Friday Spotlight - December 13, 2013

Happy Friday!

Our spotlight this week is one of my favorite videos (and one of my favorite features of Oracle Linux), Ksplice. If you're not familiar with Ksplice, it's really astounding – it allows you to update the Linux kernel while it is running and without needing to restart. It's just amazing technology, and it comes with your Oracle Linux support subscription.

In the video below, Oracle's Tim Hill described a few different scenarios of how Ksplice can be used (click the image to hop over to the Oracle Linux YouTube channel and play the video):

See you next week!

Oracle Linux Friday Spotlight - December 6, 2013

Happy Friday!

By now, you've probably heard about the release of Oracle Linux 6.5. One really cool thing about this release is that Unbreakable Enterprise Kernel Release 3 is installed by default, meaning you get to use all the great features of UEK R3 without needing to do a separate installation. And are there a lot of great features in UEK R3! So, our spotlight this week is on the release notes for the latest version of Oracle's Unbreakable Enteprise Kernel.

Unbreakable Enterprise Kernel Release 3 release notes

You'll learn about Control Groups, Linux Containers, DTrace, additional crypto options, improved diagnostics, the updated btrfs, better memory management, more networking options, improvements for performance, security, storage, and much more.

See you next Friday!
