Oracle Linux is on a Roll! DTrace, UEK2, Ksplice and More...
By Monica Kumar-Oracle on Oct 10, 2011
Last 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 On subsequent reboot, these patches are applied at bootup, or if a customer has installed a newer version of the kernel rpm itself, then of course the new kernel would just be loaded.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.
