Our spotlight this week is on a really cool technical tip on the Oracle Technology Network from Yuli Vasiliev called "How to Launch Linux Utilities from Oracle Database". From Yuli's introduction:
"By wrapping a Linux utility in a script and using an external database table's preprocessor directive, you can launch the utility from within Oracle Database and have the utility's output be inserted into the external table. This allows you to do things such as query operating system data and then join it with data in Oracle Database."
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.
This week, we have a really cool video done by Intel that features Oracle's Phillip Goerl discussing the Oracle Linux development model and how it relates to Intel Xeon. Click below to jump to YouTube and play the video:
LinuxCon Europe is just around the corner! This year's show is at the Edinburgh International Conference Center in Edinburgh, UK, October 21-23, 2013.
Oracle Linux is proud to be at LinuxCon once again, getting an opportunity to meet and discuss important topics with the Linux community and users. Oracle's Elena Zannoni, Director of the Linux Tools and Languages Team, will deliver a session on Monday, October 21 at 2:20PM on the topic of "Recent Advances in Linux Tracing". In this session, Elena will discuss the wide variety of tracing tools available to Linux developers (such as ftrace, perf, systemtap, and DTrace for Linux), and the pros and cons of each of these tools and include example usage of each. It will be a compelling session and we hope you can join!
And while you're at the show, please stop by Booth 28, the Oracle Linux and MySQL demo pod on Monday and Tuesday where you can talk to our experts, pick up an Oracle Linux and Oracle VM software DVD, and see Oracle Linux and MySQL in action.
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.
You are invited to the live webcast on Wed, October 30, 2013, 10am PTfeaturing Sumanta Chatterjee, Vice President, Database Engineering, and Monica Kumar, Senior Director Product Marketing of Oracle as speakers.

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!

The T10 PI data integrity demonstration features the Fusion ION Data
Accelerator shared storage solution with Oracle Linux and Emulex Gen 5 FC HBAs. The demonstration incorporates Oracle
Linux with the Unbreakable Enterprise Kernel, which supports integrity features
that leverage the T10 PI specification.
The data integrity testing was conducted by inserting corrupt data into the system and verifying that despite the insertions, data integrity on ION Data Accelerator was not compromised. Using the T10 PI specification, data corruption is noticed and fixed as it is written to shared storage, helping ensure reliability for enterprise applications. The demonstration incorporates Oracle Linux with the Unbreakable Enterprise Kernel, which supports integrity features that leverage the T10 PI specification. Additional technical details about the T10 PI reliability demo are available here.
Live demonstration of
the Data integrity solution is being featured at Fusion-io booth 1127 during Oracle OpenWorld
2013 in San Francisco from September 22-26. Read the press release.
