Announcing Oracle Linux 6.5 including the Unbreakable Enterprise Kernel Release 3

We're happy to announce the immediate availability of Oracle Linux 6 Update 5, the fifth update release for Oracle Linux 6. You can find the individual RPM packages in our public yum repository now; ISO installation images will be freely available for download from the Oracle Software Delivery Cloud soon.

Some highlights in this release include:

  • DTrace support has now been integrated in the default kernel and now supports user-space tracing of DTrace-enabled applications via the USDT provider.
  • Linux Containers (LXC) are now supported in the UEK R3.
  • The Btrfs file system now supports the send and receive subcommands that allow you to record the differences between two subvolumes, which can either be snapshots of the same subvolume or parent and child subvolumes. Btrfs now also supports replacing devices without unmounting or otherwise disrupting access to the file system.
  • The OpenFabrics Enterprise Distribution (OFED) 2.0 stack has been added, supporting a wide range of Infiniband protocols.
  • Paravirtualization support has been enabled for Oracle Linux guests on Windows Server 2008 Hyper-V or Windows Server 2008 R2 Hyper-V.

For more details on these and other new features and changes in Oracle Linux 6 Update 5, please consult the Release Notes in the Oracle Linux Product Documentation Library.

Oracle Linux 6 Update 5 is the first Oracle Linux distribution that installs the Unbreakable Enterprise Kernel Release 3 (based on mainline Linux 3.8) by default on systems based on the x86_64 architecture. The UEK R3 has already been released and announced for previous Oracle Linux 6 versions via a dedicated yum repository in October. The Red Hat compatible kernel is also included for compatibility.

For a detailed list of notable changes and improvements in UEKR3, please check the Release Notes for Unbreakable Enterprise Kernel Release 3.

As usual, Oracle Linux can be downloaded, used and distributed free of charge and updates and errata are freely available. For support, you are free to decide which of your systems you want to obtain a support subscription for, and at what level each system should be supported. This makes Oracle Linux an ideal choice for your development, testing and production systems - you decide which support coverage is the best for each of your systems individually, while keeping all of them up-to-date and secure.
