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.

Oracle Linux Friday Spotlight - November 15, 2013

Happy Friday!

Our spotlight this week is on a fantastic video that you might not have noticed because it was published just before Oracle OpenWorld 2013, and there was so much information being generated by us that it might have slipped by you. But this video is really worth taking a look at. In it, Oracle's Lenz Grimmer explains all about Linux Containers:

Announcing Spacewalk Support for Oracle Linux Basic and Premier Customers

Over the years, customers migrating to Oracle Linux have asked for options to provide a transitional solution for their existing system management tools (such as Red Hat Satellite Server) while evaluating and planning migrations to Oracle's Enterprise Manager, which is offered at no additional charge with Oracle Linux Support Subscriptions.  Based on this request, we are pleased to announce support for the open-source community project, Spacewalk, which is the basis for both Red Hat Satellite Server and SUSE Manager.  Effective today, customers with Oracle Linux Basic and Premier Support subscriptions have access to a fully supported Spacewalk build which can be setup to easily manage Oracle Linux systems.  

Spacewalk support for Oracle Linux requires Oracle Linux 6, x86_64 for the server and provides support for Oracle Linux 5 and Oracle Linux 6 (x86, x86_64) clients.  This solution requires Oracle Database 11g Release 2 as the  supported database repository for Spacewalk with Oracle Linux.  Customers may use an existing Oracle database license or they may begin by downloading a 30-day trial license from eDelivery.  Customers with Oracle Linux Basic and Premier subscriptions will automatically have access to the channel hosting the supported build.  Please review the release notes for further instructions.

Oracle Enterprise Manager is still the recommended enterprise solution for managing Oracle Linux systems and we want to provide the easiest transition path for our customers.  We are excited to offer this solution to our Oracle Linux customers while they plan and implement their migration to Oracle Enterprise Manager.

Announcing Unbreakable Enterprise Kernel Release 3 for Oracle Linux

We are excited to announce the general availability of the Unbreakable Enterprise Kernel Release 3 for Oracle Linux 6. The Unbreakable Enterprise Kernel Release 3 (UEK R3) is Oracle's third major supported release of its heavily tested and optimized Linux kernel for Oracle Linux 6 on the x86_64 architecture.

UEK R3 is based on mainline Linux version 3.8.13. Some notable highlights of this release include:

  • Inclusion of DTrace for Linux into the kernel (no longer a separate kernel image). DTrace for Linux now supports probes for user-space statically defined tracing (USDT) in programs that have been modified to include embedded static probe points
  • Production support for Linux containers (LXC) which were previously released as a technology preview
  • 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, device statistics)
  • Improved support for Control Groups (cgroups) 
  • TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints
  • FUSE file system performance improvements on NUMA systems
  • Support for the Intel Ivy Bridge (IVB) processor family
  • Integration of the OpenFabrics Enterprise Distribution (OFED) 2.0 stack, supporting a wide range of Infinband protocols including updates to Oracle's Reliable Datagram Sockets (RDS)
  • Numerous driver updates in close coordination with our hardware partners
UEK R3 uses the same versioning model as the mainline Linux kernel version. Unlike in UEK R2 (which identifies itself as version "2.6.39", even though it is based on mainline Linux 3.0.x), "uname" returns the actual version number (3.8.13).

For further details on the new features, changes and any known issues, please consult the Release Notes.

The Unbreakable Enterprise Kernel Release 3 and related packages can be installed using the yum package management tool on Oracle Linux 6 Update 4 or newer, both from the Unbreakable Linux Network (ULN) and our public yum server. Please follow the installation instructions in the Release Notes for a detailed description of the steps involved.

The kernel source tree will also available via the git source code revision control system from https://oss.oracle.com/git/?p=linux-uek3-3.8.git

If you would like to discuss your experiences with Oracle Linux and UEK R3, we look forward to your feedback on our public Oracle Linux Forum.

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!

Lenovo ThinkServer Systems Certified for Oracle VM and Oracle Linux

This morning, Lenovo announced that their ThinkServer rack portfolio has been tested and certified with Oracle VM and Oracle Linux. You can read the news release here .

By completing the testing necessary to appear on the Oracle VM and Oracle Linux Hardware Compatibility List (HCL), customers using Lenovo ThinkServer Systems are assured that their Oracle VM and Oracle Linux deployments are supported.

This is an exciting development for Oracle customers because it gives them more choice in how they want to deploy their Oracle software, including Oracle Applications, Oracle Database, and more, with Oracle VM and Oracle Linux. The combination is especially interesting in small to medium sized businesses for a number of reasons.

First, there is an extremely low barrier to entry. With zero license cost for Oracle VM and Oracle Linux, there are never any upfront fees to take into consideration. This helps small to medium sized businesses do all of their architecting, testing, and even implementation without needing to worry about license fees. Another factor that reduces the barrier to entry is Oracle VM Templates. There are over 100 of these ready to run virtual machines, pre-tested, pre-configured with popular Oracle software requiring near-zero OS, or application knowledge, ready to deploy from point of download. For SMB’s with slim IT resources, Oracle VM Templates help to radically reduce deployment time so companies can focus on growing their business.
The last piece of the puzzle for small and medium sized businesses is affordable support costs. With some of the lowest support costs in the industry, if a customer chooses to purchase support for their deployment, they are assured of a low cost, high value investment. Affordable support costs paired with zero license fees means that overall costs stay incredibly low.

And now, all of this is certified for use on Lenovo’s ThinkServer Systems!

When you look at these factors, the combination of Lenovo ThinkServer Systems and Oracle VM and Oracle Linux is a very compelling option.
