VISIT ORACLE LINUX AT EMC WORLD

We are at EMC World, Las Vegas, May 6-9 !


Come and visit us at Booth #316

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.

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.

Announcing Ksplice Inspector!

Everyone knows a good inspector is crucial when buying a home or looking for clues in a "whodunit". And now you also have an "inspector" for your Linux kernel!

Today Oracle released a new tool called the Ksplice Inspector enabling Linux users to analyze kernel updates available for their Linux kernel. With so many kernel updates released, it can be difficult to keep track. At Oracle, we monitor kernels on a daily basis and provide bug and security updates administrators can apply without a system reboot. To help out, the Ksplice team at Oracle has produced the Ksplice Inspector, a web tool to show you the updates Ksplice can apply to your kernel with zero downtime.

Read the Ksplice blog article for more details on this new tool and who can use it.

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.
