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!
