Friday Spotlight: Frequently Asked Questions about Oracle Linux

It is Friday and that means it is time for our Spotlight! 

Our spotlight today is the recently updated Oracle Linux FAQ. This is an excellent document that features some of the questions that everyone asks about Oracle Linux and Oracle Linux support. We cover variety of topics including general definitions, compatibility, support, pricing, indemnification, migration and many more.. 

Here's one of the questions as an example:

Q: What is DTrace for Oracle Linux?

A: DTrace is a comprehensive dynamic tracing framework that was initially developed for the Oracle Solaris operating system, and is now available to Oracle Linux customers. DTrace is designed to give operational insights that allow users to tune and troubleshoot the operating system. DTrace provides Oracle Linux developers with a tool to analyze performance, and increase observability into the systems they own to see how they work. DTrace enables higher quality applications development, reduced downtime, lower cost, and greater utilization of existing resources. It is available to download from ULN for Oracle Linux Support customers. 

Read more in the newly published FAQ.

Have a great weekend!

Friday Spotlight: Accelerating MySQL on Oracle Linux with Flash

Happy Friday!

Our spotlight this week is on a brand new white paper that can help you get the most out of MySQL running on Oracle Linux, with the help of Oracle's Sun Flash Accelerator F80 PCIe card. To give you an idea of the Oracle Linux part of this, here is an except from the paper's intro:

"Oracle Linux with Unbreakable Enterprise Kernel (UEK) was chosen for this study for several key reasons including its upstream support for the latest hardware relevant to modern data center operations, and SSD support and performance features such as SSD detect. In addition, MySQL database workloads benefit from the platform’s deep integration with the solution stack, optimizations resulting from industry collaborations and enhancements in the UEK.

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.

Release Candidate for Unbreakable Enterprise Kernel Release 3 is now available

We are happy to announce the availability of the release candidate for 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 release candidate version is 3.8.13-16 and includes additional improvements and bug fixes in preparation for our final release.  As a recap, the features users can expect in this release include:

  • Inclusion of DTrace 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!
