Performance Issues with Transparent Huge Pages (THP)

One key reason customers choose Oracle Linux is the investment Oracle makes in optimizing Linux for demanding workloads.  Part of this work includes extensive testing for I/O intensive workloads, like the Oracle Database. A common test used at Oracle to measure I/O throughput and performance is the Oracle Orion Calibration Tool, which simulates the I/O workloads of an Oracle Database. Recently, the Oracle Linux team discovered a significant lag in I/O performance, which was later traced to a feature in the Linux kernel, Transparent Huge Pages (also known as THP). During these tests, our engineering teams discovered THP introduced a 30% performance degradation in I/O throughput. When Transparent Huge Pages were removed from the kernel, performance values returned to their expected levels.

Our engineers have been working with the community to identify the root cause of this performance problem, which also impacts other projects, such as Hadoop. Oracle’s kernel engineers have traced the performance issues with Transparent Huge Pages to its use of swappable hugepages. Prior to THP, hugepages were not swappable. It appears the overhead generated by this implementation is the root cause of the deterioration seen in performance when the feature is enabled (compiled) in the kernel. Our kernel engineers are working on several changes to the code which they believe will improve performance with THP, but the final resolution will take time to develop, test and release.

Due to the impact this feature has on performance with applications like the Oracle Database and the timing of a final fix, Oracle Linux will disable Transparent Huge Pages in the Unbreakable Enterprise Kernel, beginning with Quarterly Update 5 for the Unbreakable Enterprise Kernel, Release 2 (version 2.6.39-400.209.1). To maintain binary compatibility with the Red Hat distribution, the Red Hat Compatible kernel will be left as is, with Transparent Huge Pages enabled. In addition, the Oracle Database team has released an alert recommending all customers disable THP in all Linux systems running RAC and even those systems running single instances, due to instability. Please note that THP is not used by the Oracle Database, the recommendation is to use huge pages. Additional information for huge pages can be found in your Oracle Database documentation or on My Oracle Support.

Our engineers will continue to work with others in the community on a final resolution to the performance issues seen with Transparent Huge Pages. Once a fix is available, we will re-enable this feature in the Unbreakable Enterprise Kernel.

Unbreakable Enterprise Kernel Release 2 Quarterly Update 5 has been released

We are pleased to announce the availability of the 5th quarterly update update release for the Unbreakable Enterprise Kernel Release 2 (version 2.6.39-400.209.1) for Oracle Linux 5 and Oracle Linux 6.  This release includes driver updates as well as a consolidation of bug fixes and security updates.

 Notable changes include:

  • Xsigo virtual host adapter and network drivers to support Oracle SDN (Software Defined Network), previously known as Xsigo Fabric Accelerator.
  • LSI Fusion-MPT SAS 3.0 driver to support up to 12 Gb/s host controllers.
  • XEN improvements, such as the indirect-descriptor feature, which increases throughput and reduces latency for block I/O.

For additional details, please refer to the release notes.

Binary RPMs can be downloaded and installed using yum from the Unbreakable Linux Network (ULN) as well as Oracle's public-yum server.  The Unbreakable Enterprise Kernel is installed and booted by default on Oracle Linux.  See this article on Oracle Technology Network for details on how to install and update the kernel.

The source code, including the full revision history, is available from Oracle's git repository at https://oss.oracle.com/git/?p=linux-uek-2.6.39.git;a=summary.

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.

Reasons You Should Consider Migrating From SUSE Linux (SLES) to Oracle Linux

Each day we receive inquiries from Oracle customers who are interested in migrating from SUSE Linux Enterprise Server (SLES) to Oracle Linux.  As a result, we hosted a webcast to provide additional information for customers who are considering migration and there are a few key points from the webcast I would like to share.

First, I believe all Oracle customers benefit from using Oracle Linux for their Oracle workloads.  Oracle Linux is the corporate Linux standard for all development groups at Oracle.  The Oracle products you use are developed on Oracle Linux.  This development standard creates a natural synergy between Oracle Linux and the Oracle application stack.  Oracle Linux receives over 128,000 hours of testing  from Oracle products, including extensive regression testing, while SLES receives only basic installation testing as an operating system. 

Oracle Linux subscriptions also offer tremendous value.  With Oracle Linux Basic and Premier Support subscriptions you receive 24x7 support, 365 days per year with unlimited incidents. Compared to SLES, Oracle Linux can significantly reduce your operating expenses which translates directly to your bottom line.   Let's take, as an example, a 4-socket system hosting several virtual machines with 24x7 support:

 Oracle Linux Basic Support Subscription
 SLES Priority , 4-socket, Virtual Subscription
 $1,199 annually (per server)
 $3,878 annually (per server)

As you can see in the table, the SLES Priority Subscription list price is $3,878 annually, per server.  For Oracle Linux, the equivalent Basic subscription would be $1,199, about 69% less.   If you had 100 servers in your data center, this would be an annual savings of $267,000!   In addition, the Oracle Linux Basic and Premier Subscriptions include solutions for high availability and system management, at no additional charge.  To receive these features with SLES, you must purchase additional extension subscriptions per server.  Using the previous example, for the SUSE Linux High Availability extension you will pay an additional $1,398 for each 4-socket server in the cluster, per year.  This now represents a 77% savings with Oracle Linux.  If you want to use their system management tools, there is a separately priced extension.  As you can see from the example, the SUSE extension-based pricing model quickly adds up.  With Oracle Linux, our pricing is straightforward and subscriptions include more features, providing greater value for you.

There are also features you will only find with Oracle Linux.  For example, what if I were to tell you Oracle Linux provides all bug and security errata on our public yum repositories and it is free, would you be interested?  With Oracle Linux, you receive:

  1. Free ISO downloads for each major and minor releases
  2. Free software channels for bug fixes and security errata
  3. All source code, including changelogs, for free.  No subscription required.
  4. The ability to freely redistribute without a requirement to modify copyrights, trademarks, or sign additional agreements
  5. Freedom from restrictive support term requirements to cover all systems with subscriptions.  Oracle Linux support is only required for systems that you intend to receive support services for.  Systems that are static, and don't need support (testing, development, etc.) do not have to be covered by a subscription.

With SLES, you can download the product under a 60-day evaluation, but after 60 days you'll need a subscription if you wish to receive any further updates to the software or to access the source for those updates.  You will not have access to the changelogs for the source and if you want to distribute you will need to remove all trademarks, trade dress and logos before doing so.  In addition, depending on your buying program, you may be required to cover every instance of SLES with a subscription, regardless of whether you require support for that system.

There are also unique features for Oracle applications which are offered only with Oracle Linux.  One example is Oracle Database Smart Flash Cache.  Introduced originally with Oracle 11g Release 2, Oracle Database Smart Flash Cache provides the ability to extend the database buffer cache without adding additional main memory by expanding to second level cache on flash memory.  This ability to leverage flash improves Online Transaction Processing (OLTP) environments by improving transaction throughput and application response times.  Oracle Linux is the only Linux distribution with support for this feature. 

Also, have you ever considered what the actual cost is for system downtime in your data center?  Every data center schedules maintenance for production environments and for every maintenance window needed, an administrator must coordinate with multiple groups to plan and schedule downtime.  When you consider large systems, like the Oracle database, the man-hours needed to coordinate, schedule and implement maintenance updates quickly add up.  What if I told you Oracle Linux Premier Support subscriptions include Ksplice, a service for installing kernel updates without requiring a system reboot.  Ksplice eliminates many of the common maintenance scenarios which result in a system restart, allowing administrators to keep up to date with the latest kernel errata, without bringing down the server.

Finally, let's end by talking about support.  As everyone knows, Linux is open source and when you choose to purchase subscriptions for Linux, you are buying access to a vendor's knowledge and expertise.  With Oracle Linux, customers have access to the best support professionals in the industry, who not only understand the operating system but they also understand the Oracle applications running on it.  You will spend less time being shuffled from vendor to vendor when you have a critical issue, producing quicker resolutions for your production systems.

I have highlighted several key reasons why you should consider a migration from SLES to Oracle Linux and I encourage you to  review the materials we have available on the Migration Made Easy web site, where you will find additional tips and guides to get you started.  If you have additional questions or you are ready to talk about your migration, please contact us for more information.

Q&A About the Latest Oracle Linux Releases

We sat down with Monica Kumar, Senior Director, Oracle Linux, Oracle Virtualization, and MySQL Product Marketing, to discuss the latest update on Oracle Linux.


Q. What are the latest Oracle Linux releases? 

A. Oracle Linux 5.9 and Oracle Linux 6.4 represent the latest releases of Oracle Linux. These releases are built on top of Oracle Linux 5 and 6 respectively and include updates supporting new hardware and driver features, as well as bug fixes and security updates. For additional details, please see the 5.9 release notes and 6.4 release notes.

Q. Why would customers want to update their Oracle Linux systems to the latest release? What advantages will it give them?

A. Updates play a critical role in the overall lifecycle of an operating system release. An update release provides an opportunity for customers to leverage new hardware features as well as apply critical bug fixes and security updates. Oracle Linux 5.9 is also a consolidation of previously released errata published since the release of 5.8 – and the same holds true for 6.4. As part of Oracle Linux, we also offer an innovative and modern kernel – Unbreakable Enterprise Kernel. The combination of Unbreakable Enterprise Kernel with the latest bug fixes and new hardware support helps improve performance, enhance stability and enable systems to remain secure.

Q. Why do customers choose Oracle Linux? What do they get from Oracle Linux that they couldn't get by using RHEL or SUSE or a non-commercially supported distribution?

 A. Oracle Linux offers many benefits. Key benefits include:

  1. Technology: Latest innovations (with tracking mainline, optimizations from Oracle Engineered Systems, and Unbreakable Enterprise Kernel is the culmination of this technology excellence, offering enhanced performance, reliability and a more modern Linux distribution), as well as unique features such as Ksplice, DTrace, and support for popular file systems including ocfs2 besides the others.
  2. Testing/ Deployment best practices: over 100,000 hours of QA/day using Oracle Linux – most tested distribution with enterprise workloads and over 160 validated configurations.
  3. Support: 24/7 world-class Linux support in 145 countries; by far the widest and largest support network over Red Hat or SUSE
  4. Cost: Lowest cost support
  5. Free Access to software: free download of binaries and patches

Read detailed information regarding RHEL vs Oracle Linux

Q. What does Oracle give back to the Linux kernel community?

A. New Linux kernel development is focused on working with Linus and the mainline kernel community, where we, like other Linux distribution vendors, contribute significant amounts.  Over time, those mainline development projects trickle down into an OS distribution like Oracle Linux 6 through Unbreakable Enterprise Kernel which is a great vehicle – and how we introduce new Linux kernel features into Oracle Linux and provide it to customers. Oracle has a long history of developing open source projects and working with the Linux kernel community. We are active contributors to many features found in the mainline kernel today, including OCFS2, Btrfs, NFS, XEN, to name just a few. In addition, our business model for Oracle Linux is to focus on providing the best operating system for mission critical workloads, and contributing the work we do back to the mainline community. Our git repository for the Unbreakable Enterprise Kernel is publicly available on oss.oracle.com/git so anyone can see our development work and our contributions. In addition, we make Oracle Linux freely available, including all of our errata, whether you have a support subscription or not.

See this link for more on Oracle’s contributions to Linux.

Q. Why is Oracle Linux better for customers than using the most current version of Red Hat Enterprise Linux? What's the value for customers?

A. Oracle Linux including the Unbreakable Enterprise Kernel  is developed to provide high performance and stability for mission-critical applications. Users benefit from the innovations and improvements occurring in the mainline Linux community, which we deliver rapidly with Oracle Linux. In addition, Oracle Linux is the most well tested distribution for enterprise workloads, especially Oracle workloads. We conduct over 100,000 hours/day of testing at Oracle using Oracle Linux. Additionally, support of Oracle’s Engineered Systems plus the enterprise application knowledge that we have, is unmatched by our competitors.

The technical support we provide with Oracle Linux also includes important bug fixes that Red Hat may choose not to release. For our customers, these fixes are critical and it is one of the many reasons they choose Oracle Linux. In addition, with capabilities like zero-downtime kernel updates through Ksplice, they receive features that are not offered by Red Hat.

Q. What is being planned for the next release and what is the predicted timing of the next release?

A. Oracle continues to focus on features which improve performance and the innovations found in the mainline Linux community. We are currently working on the next generation of the Unbreakable Enterprise Kernel for Oracle Linux.

We expect update releases for both Oracle Linux 5 and Oracle Linux 6 and a new release of the Unbreakable Enterprise Kernel in calendar year 2013.
