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!

Beta 1 of Unbreakable Enterprise Kernel Release 3 now available

We are happy to announce the availability of Beta 1of the Unbreakable Enterprise Kernel Release 3 for Oracle Linux 6. The Unbreakable Enterprise Kernel Release 3 (UEK R3) is Oracle's third major release of its heavily tested and optimized operating system kernel for Oracle Linux 6 on the x86_64 architecture. It is based on the mainline Linux version 3.8.13.

The 3.8.13-13 release also updates device drivers and includes bug and security fixes. Some notable improvements in functionality and new features include:

  • Numerous stability and scalability enhancements
  • Inclusion of DTrace 0.4 for Linux into the kernel (no longer a separate kernel image). DTrace for Linux now now supports probes for user-space statically defined tracing (USDT) in programs that have been modified to include embedded static probe points.
  • Btrfs file system improvements (subvolume-aware quota groups, cross-subvolume reflinks, btrfs send/receive to transfer file system snapshots or incremental differences, file hole punching, hot-replacing of failed disk devices)
  • Improved support for Control Groups (cgroups) and Linux containers (LXC).
  • The ext4 file system can now store the content of a small file inside the inode (inline_data).
  • TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints.

The Unbreakable Enterprise Kernel Release 3 can be installed on Oracle Linux 6 Update 4 or newer, running either the Red Hat compatible kernel or a previous version of the Unbreakable Enterprise Kernel. The UEKR3 beta kernel packages and supporting userland utilities can be installed using the yum package management tool from the public-yum server.

For installation instructions and more details on the new features, changes and any known issues, please consult the Release Notes found on our public beta site.

We've created a dedicated public beta test discussion forum — please join us and share your observations and impressions there!
