FRIDAY SPOTLIGHT: Why Oracle Linux for Modern, Cloud-Enabled DataCenter?

Happy Friday everyone!

We have a great video to share with you this week. In this animated video,  learn how Oracle Linux includes the features and tools you need for your modern, cloud-enabled data center. 

While Oracle Linux is open source and includes standard technologies, tools, and features, Oracle extends the release to deliver a complete, integrated, and supported platform for performance-driven production workloads. In addition to the Red Hat Compatible Kernel (RHCK), Oracle supplies the optimized Unbreakable Enterprise Kernel (UEK), which was first developed to support highly scalable Oracle Engineered Systems. Support for Oracle Linux is affordable and the release is free to download and distribute, unlike other commercial Linux distributions. To add even greater value, Oracle bundles additional capabilities—Ksplice for zero-downtime kernel updates, support for Docker, Linux Containers, OpenStack, Oracle Clusterware for High Availability (HA), and more—at no additional charge with an Oracle Linux Premier Support contract. As a result of these additions, companies receive greater value from their Linux support investment, allowing IT organizations to achieve a higher return on investment.

FRIDAY SPOTLIGHT: Best Videos about Oracle Linux from OOW15

There's something better about hearing a topic in a video, it is as if you have been transported to that location without interruptions from other elements. You also get to know the presenter at a different level; how he gets excited about his products, his projects or the environment around him. For this reason, we wanted to dedicate this Friday to all the Oracle OpenWorld videos that feature Oracle Linux.  It will give you an amazing insight and transport you to San Francisco, to that moment!

Keynotes: 

First we want to start with Oracle OpenWorld 2015  keynotes that have featured Oracle Linux announcements. We recommend watching Larry Ellison and Intel CEO, Brian Krzanich's keynotes.

theCUBE Videos 

The second video set is Oracle Executives that are featured in SiliconAngle's theCube. Wim Coekaerts, Sr.VP of Linux and Virtualization Engineering, had been very busy during Oracle OpenWorld this year with some great interviews. His videos are always fun to watch and very informative about latest technologies like docker, containers and OpenStack. The second video is from our Chief Architect, Edward Screven. You can hear his views on Open Source in the video below.

Partner Videos from the Showcase 

Our third video set covers some of our great ISV and IHV Partners who have participated in our OracleLinux, Oracle VM and OpenStack Showcase. 

amitego AG - Oracle OpenWorld 2015

Intel - Oracle OpenWorld 2015

QLogic - Oracle OpenWorld 2015

Learn About Using DTrace with Oracle Linux

DTrace is a performance analysis and troubleshooting tool. DTrace allows dynamic tracing by defining probe points dynamically. Probes and actions at probe points are defined by commands and scripts written in the D language.

To learn about using DTrace with Oracle Linux, view this video and learn to: 

  • Subscribe to the DTrace channel on ULN
  • Install the DTrace software packages
  • Load the DTrace kernel modules
  • List DTrace probes
  • Use the DTrace command line interface
  • Run DTrace scripts
  • Access the DTrace guide and DTrace tutorial

You can learn more about DTrace and other advanced linux tasks by taking the training course relevant to the version of your operating system:

DTrace is one of the topics tested in the Oracle Certified Professional: Oracle Linux 6 Advanced System Administration exam.

New Userspace Patching with Oracle Ksplice!

Last week, Larry Ellison introduced userspace patching with Oracle Ksplice. This is a groundbreaking addition to the already extensive capabilities of Ksplice, giving administrators the tools they need to cope with security threats and other issues without impacting running systems.

If you're unfamiliar with Ksplice, it provides zero-downtime patching (also known as “live patching") for Linux. With Ksplice, updates and errata (CVEs, etc.) can be applied to running systems without restarting applications or rebooting. This is a boon for organizations since scheduling downtime across a server farm is a significant event, and many companies using a variety of operating systems only perform patches periodically in a regular cycle. But being able to apply critical updates immediately–or remove them, if necessary–without impacting servers even under heavy load allows administrators to reduce the window of vulnerability for security issues to the bare minimum, making systems more secure. A fantastic primer on Ksplice can be found in Wim Coekaerts' blog post The Magic of Ksplice.

While Ksplice has been a great tool for applying patches without downtime, it has been focused exclusively on kernel patches. That is, until last week with the announcement of userspace patching for Ksplice.

Why is userspace patching important? Well, patching the kernel as Ksplice has done for years solves a number of issues. It lets you patch security vulnerabilities at the kernel level, it allows you to apply patches to do diagnostics, and so on. But applications rely on services available above the kernel (in “userspace”) to do many of their tasks. For example, glibc, the GNU C Library, is the standard C and C++ library used by applications on Linux. And OpenSSL provides secure networking services for applications so applications don’t have to implement these features from scratch. But patching the kernel doesn’t help with changes that need to be made in these system wide libraries.

These standard libraries are very useful because they allow the community to optimize and standardize on how common tasks are accomplished. But since they are used by so many applications, a flaw in one of these libraries creates widespread exposure. Just such an exposure happened with the Heartbleed Bug, where an issue with OpenSSL left thousands of servers at risk.

With userspace patching in Ksplice, Oracle can now provide you with the tools to patch these userspace libraries without downtime. At Oracle OpenWorld last week, we were showing attendees in the Oracle Linux, Oracle VM, and OpenStack Showcase how we can apply userspace patches for the Ghost and Heartbleed vulnerabilities, check that the systems were indeed secured, and then roll those patches back to their unsecured state, all in a couple of minutes and without stopping running applications. This is the power of the new userspace feature of Ksplice. In this first release of userspace patching, the focus is on glibc and OpenSSL since this will cover many of the security related issues customers will run into. 

With the addition of userspace patching, a great tool just got even better. Ksplice can now patch the running Linux kernel and also patch userspace glibc and OpenSSL without downtime. Userspace patching is a huge development in zero-downtime patching, and another tool in the toolbox for administrators needing to cope with critical updates. This brings the magic of Ksplice from the kernel up to userspace, making your systems safer.

Userspace patching for Ksplice is available now in the enhanced Ksplice client for customers with Oracle Linux Premier Support. You can read about it in the latest Ksplice documentation and when you’re ready to try it out, you can enable it on the Unbreakable Linux Network and install it on your systems.

Friday Spotlight: Start Reserving Your Spots in Oracle OpenWorld 2015 Sessions

Happy Friday!

With Oracle OpenWorld 2015 a little over a month away, it's time to start figuring out which sessions you're going to attend! You can start putting your schedule together today with My Schedule (if you're an OpenWorld veteran, this was called "Schedule Builder" in previous years). And of course, we hope you join us in several of our sessions and hands on labs about Oracle Linux, Oracle VM, and Oracle OpenStack for Oracle Linux.

To make it a little easier to find content that is interesting to you, we have two "Focus On" documents that you can have a look at and bookmark. The Focus On docs format really nicely on mobile devices, and are updated in real-time in case rooms change or anything else unforeseen happens, so they are a great resource to have bookmarked on your phone.


Since Oracle OpenStack for Oracle Linux spans both Oracle Linux and Oracle virtualization, you'll find those sessions in both.

We'll go into more detail in the coming weeks, but I'd like to highlight a couple of sessions to start with. Even if you can't join us in any other sessions, I highly recommend signing up for the General Sessions from Senior Vice President Linux and Virtualization Wim Coekaerts. These are always our most popular sessions, and it's a fantastic opportunity to get the very latest information on industry trends and the direction of Oracle's Linux and virtualization teams.

Friday Spotlight: Building the Modern Cloud-Enabled Data Center

Happy Friday!

Thanks so much to everyone that stopped by our booth and went to our sessions at LinuxCon North America 2015! We had a great time and it was fantastic getting the opportunity to meet and speak with many of you in person.

Some of the things that are top of mind for Linux users are (obviously!) the cloud impact on data center design, container technologies, OpenStack, security, and so on. So I looked through our archive to find a webcast that I think does a great job outlining how Oracle Linux approaches these things.
