Stay tuned for more updates as we count down to Oracle Openworld 2013.
Oracle today announced that customers and partners continue to rapidly adopt Oracle Linux to increase the scalability, reliability and performance of their critical applications and systems.
to Gartner (March 2013), Oracle Linux 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(1).
Recent important announcements with Dell, Microsoft, and Salesforce.com, around support for Oracle Linux, further demonstrate Oracle Linux momentum with partners.
“Epsilon offers a broad array of data-driven, multichannel marketing
solutions for many of the biggest brands in the world. Our information
systems have been experiencing substantial growth year-over-year, with
increased demand for real-time reporting, and high performance
transaction processing. To enable customers to interact with a brand in a
more dynamic real-time manner, we knew our infrastructure had to be
comprehensive, well integrated and scalable. With our Oracle Exadata
Database Machines running Oracle Linux, we are achieving transactional
processing speeds that were previously not attainable. Oracle’s
technologies and world-class support have been instrumental in enabling
us to deliver new value-add services and greater efficiency for
clients,” said Jeff White, vice president, technology, strategic
database services at Epsilon.
We're pleased to announce that the fourth quarterly update release of the Unbreakable Enterprise Kernel Release 2 (Version 2.6.39-400.109) for Oracle Linux 5 and 6 has been published. This release includes driver updates as well as fixes for bugs and security issues.
Binary RPMs can be downloaded and installed using yum from the Unbreakable Linux Network (ULN) as well as our public-yum server. The Unbreakable Enterprise Kernel is installed and booted by default on Oracle Linux. See this article on the Oracle Technology Network for details on how to install and update it.
Our team will be at Kiosk #1- Data Integrity: Preventing Silent Data Corruption with Oracle Linux
EMC and Oracle have partnered since 1995, helping over
70,000 customers optimize their Oracle software on EMC virtual infrastructure. One of those partnerships had contributed to
development and enhancement of data integrity features. Data corruption can go unnoticed and recovery
is difficult and costly, or even impossible. The EMC and Oracle Data Integrity
solution protects mission critical application information from corruption and
eliminates potential costs and downtime. This is made possible based on tight
integration with the T10 PI standard (previously known as Data Integrity
Field or DIF), which prevents silent data corruption, ensuring that incomplete
and incorrect data cannot overwrite good data.
Visit us at booth #316 to receive Oracle Linux/Oracle VM DVD Kit, collateral about Data Integrity as well as other goodies.
We will also showcase Oracle VM Storage Connect: The Ease of Managing and Provisioning Storage in Kiosk 2.
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:
All source code, including changelogs, for free. No subscription required.
The ability to freely redistribute without a requirement to modify copyrights, trademarks, or sign additional agreements
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.

When : Thursday, April 11 at 1
Senior Vice President of Linux and Virtualization Engineering, Wim Coekaerts,
on Thursday, April 11 at 1 p.m. PT for an hour of tweets about all things
Please submit your questions on Twitter by using #AskOracleExec. Wim will be responding to questions using the @ORCL_Linux Twitter handle.
Wim Coekaerts is the Senior
Vice President of Linux and Virtualization Engineering for Oracle. He is
responsible for Oracle's complete desktop to data center virtualization
product line as well. Mr. Coekaerts
joined Oracle in 1995.
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
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
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:
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.
Deployment best practices: over 100,000 hours of QA/day using Oracle
Linux – most tested distribution with enterprise workloads and over 160
world-class Linux support in 145 countries; by far the widest and largest
support network over Red Hat or SUSE
Q. What does Oracle give back to the
Linux kernel community?
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
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
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.
