Public yum now powered by Akamai

The availability of free updates and errata has significantly increased the popularity of Oracle Linux. According to a recent Gartner Study from March 2013, Oracle Linux is placed in the top three in the Linux server operating system market, growing more than 80 percent year-over-year in 2012, which outpaced the overall Linux server operating system market growth.

This popularity was also reflected in our download numbers – recently, we were serving  over 80 TB worth of data each month, and this number keeps on growing. In order to ensure continued satisfaction with this free service, we now switched the US-based public-yum.oracle.com server to use the Akamai content delivery network for distributing all the available RPM packages for Oracle Linux globally.

This increases the performance for obtaining updates and security fixes for Oracle Linux – no matter where you are in the world. With the help of the Akamai CDN, the download experience will now be similar, regardless of your geographic location.

Please note that you need to connect to the public yum service by host name. If your yum clients are configured to access the public yum server by its public IP address, you won't benefit from increase in performance, as Akamai uses DNS to redirect the load. Please check your configurations accordingly!

Announcing Ksplice Inspector!

Everyone knows a good inspector is crucial when buying a home or looking for clues in a "whodunit". And now you also have an "inspector" for your Linux kernel!

Today Oracle released a new tool called the Ksplice Inspector enabling Linux users to analyze kernel updates available for their Linux kernel. With so many kernel updates released, it can be difficult to keep track. At Oracle, we monitor kernels on a daily basis and provide bug and security updates administrators can apply without a system reboot. To help out, the Ksplice team at Oracle has produced the Ksplice Inspector, a web tool to show you the updates Ksplice can apply to your kernel with zero downtime.

Read the Ksplice blog article for more details on this new tool and who can use it.

Free Updates and Errata for Oracle Linux

ISO images of the Oracle Linux installation media as well as individual binary RPMs (and the sources) of major and minor releases (Updates) have always been freely available for download, use and distribution, ever since we started the Oracle Linux support program.

We're now taking this a step further: in addition to the above, we will now also provide updated packages or errata for free from separate yum repositories on http://public-yum.oracle.com. If you would like to keep your Oracle Linux system up to date, you can now do so by subscribing your system to the respective "_latest" repository for your distribution, e.g. "ol6_latest" for Oracle Linux 6. See the installation instructions on the public yum front page and the "How to subscribe to the free Oracle Linux errata yum repositories" article on the OTN Garage blog for details on how enable these repositories and to obtain the updates.

If you would like to also receive free updates to the Unbreakable Enterprise Kernel Release 2, make sure to enable the "[ol6_UEK_latest]" repository as well - updates to the kernel will be made available from this separate channel until it is included in the next set of installation media.

Now what does this mean for Oracle Network Support? Getting access to the updates and errata was just one part of the offering – the following benefits will be available with an Oracle Linux Support Subscription only:

Wim also published a blog post with his take on the announcement.

Rebootless updates: now available for Red Hat Enterprise Linux, too!

As you probably know by now, we in the Oracle Linux Team are quite enthusiastic about Ksplice. Just in case you haven't heard about Ksplice yet, this technology allows you to apply security fixes and upgrades to the Linux kernel while your system is running, without having to reboot your server. Your applications remain unaffected — there is no service disruption or performance impact involved.

Ksplice was added to our Oracle Linux Premier support subscription some time ago (at no additional cost) and customers rely on it to ensure their systems are always up to date and fully patched, even if the next scheduled maintenance window is still days (or weeks) ahead.

Before, Ksplice patches were only provided for customers running Oracle Linux with the Unbreakable Enterprise Kernel. Today, we’re extending our support offering: Ksplice zero downtime kernel updates are now available for the Red Hat compatible kernel on Oracle Linux 5 and 6 as well. And if you are running Red Hat Enterprise Linux without Oracle Linux support and you’d like to try Ksplice, sign up for our 30-day free trial.  

In addition to that, we will continue to provide Ksplice patches for Fedora and Ubuntu Linux for free. If you want to learn more about Ksplice, check out Wim's OTN article "Using Oracle Ksplice to Update Oracle Linux Systems Without Rebooting" and Waseem's Ksplice Demo Video on the Oracle Linux YouTube Channel.

Now Available: Zero Downtime Updates for Oracle Linux with Ksplice

Ksplice, which was recently acquired by Oracle in July 2011, is now available as part of Oracle Linux. With Ksplice, users can update the Linux operating system (OS) kernel, while it is running, without a reboot or any interruption. Only Oracle Linux offers this unique capability, making it possible for users to make important Linux updates without burdening the team with the operational cost and disruption of rebooting for every update to Linux.

Available at no additional charge to existing and new Oracle Linux Premier Support customers, Oracle’s Ksplice Uptrack service is easy to access. Oracle Linux Premier Support subscribers can request a Ksplice access key through Unbreakable Linux Network (ULN). After installing Ksplice, you can easily apply all important Linux kernel updates without needing to reboot. No configuration changes or initial reboot is needed to install. Under the hood, Ksplice loads a Linux kernel module that rewrites portions of the running kernel to apply the updates.

Read the Ksplice data sheet.

Join us on September 20th at 9:00 am US PT for a Ksplice webcast and get more details.
