Oracle Linux is on a Roll! DTrace, UEK2, Ksplice and More...

Oracle Linux PenguinLast week's Oracle OpenWorld was an incredible success. By any standards. From the vast amount of content that was delivered, the passion and zeal displayed by attendees that were eager to learn, share and network, the larger than life keynotes, the food, the activities, the keynotes, the drama, the large scale, entertainment with Sting and Tom Petty, everything was meticulous!

Hats off to the Oracle employees who work day in and day out to make this experience possible for our attendees!

Now that we are back to our normal work routine, I looked back at all the announcements/discussions and wanted to share a few with you that are relevant to the Linux community.

1. Unbreakable Enterprise Kernel Release 2 (Beta): 

We announced the availability of Unbreakable Enterprise Kernel 2 (UEK2) beta which is based on Linux 2.6.39 and includes featuures such as btrfs in production, Linux container, Open vSwitch and more. UEK2 beta is freely available to everyone. All you need is Oracle Linux 6 installed (also freely available from edelivery) and connect to the Unbreakable Linux Network (ULN) if you are an existing customer or if you just want to play with cool new stuff, use our public yum repository. Check out Wim Coeakert's blog entry with details on UEK2.

2. DTrace in Linux:

Another interesting feature we announced and is already available to Oracle Linux customers is "DTrace." We released a preview of DTrace which is made available to Oracle Linux support subscribers. Wim is also on a roll as you can see from his detailed blog entry on DTrace!

3. Zero downtime updates with Ksplice:

Ksplice has to be the hottest thing in Linux! Since early September Oracle Linux customers with a Premier support subscription, or Oracle customers with Oracle Premier Support for Systems and Operating Systems, have access to the newly added "zero downtime kernel updates" with Ksplice. Ksplice updates are kernel updates that can be applied on a running system. Note that we are not just talking about being able to install a new update of a package while the system is running and it then have take effect after a reboot or restart. The ksplice patches are immediately applied to the running Linux kernel and are effective immediately. On subsequent reboot, these patches are applied at bootup, or if a customer has installed a newer version of the kernel rpm itself, then of course the new kernel would just be loaded. How cool is this! Read Ksplice details here.

We are on a roll! Oracle is seriously investing in Linux and is driving Linux innovation hand in hand with the Linux community. Not only is Oracle Linux Support still much lower cost, but it is also superior in the features and functionality we bring to customers. Oracle Linux is the BEST Linux for any enterprise computing needs. Period.

Now Available: Zero Downtime Updates for Oracle Linux with Ksplice

Ksplice, which was recently acquired by Oracle in July 2011, is now available as part of Oracle Linux. With Ksplice, users can update the Linux operating system (OS) kernel, while it is running, without a reboot or any interruption. Only Oracle Linux offers this unique capability, making it possible for users to make important Linux updates without burdening the team with the operational cost and disruption of rebooting for every update to Linux.

Available at no additional charge to existing and new Oracle Linux Premier Support customers, Oracle’s Ksplice Uptrack service is easy to access. Oracle Linux Premier Support subscribers can request a Ksplice access key through Unbreakable Linux Network (ULN). After installing Ksplice, you can easily apply all important Linux kernel updates without needing to reboot. No configuration changes or initial reboot is needed to install. Under the hood, Ksplice loads a Linux kernel module that rewrites portions of the running kernel to apply the updates.

Read the Ksplice data sheet.

Join us on September 20th at 9:00 am US PT for a Ksplice webcast and get more details.

Webcast: Eliminating Silent Data Corruption in Linux

Silent data corruption can be significantly detrimental and costly to a business. Oracle's Martin Petersen, our lead Linux Kernel developer for data integrity, has worked with the mainline kernel community to incorporate a data integrity specification into the Linux kernel that eliminates silent data corruption in Linux. This contribution enables comprehensive data integrity capabilities across the entire apps to disk stack, allowing customers to reduce costs and increase efficiencies.

Join Oracle's Linux technology experts for a webcast on Thursday, Dec. 16 at 9am US PT, as they discuss how Oracle Linux with its new Unbreakable Linux Kernel helps eliminate silent data corruption by reducing the potential for incorrect data to be writtem to the disk, decreasing application and database errors and system downtime.
