ISV Certification is Accelerating on Oracle Linux

A typical question I receive on a daily basis from Independent Software Vendors (ISVs) is how they can work with Oracle to certify their applications on Oracle Linux.  The quick answer I give them is “Paper Cert it!” That might not explain the whole process, but it is that easy. Let me give some background for those who are unfamiliar with Oracle Linux.

Oracle Linux is binary compatible to Red Hat Enterprise Linux (RHEL). This means your applications will run the same on Oracle Linux as they do on RHEL. That’s because Oracle Linux with the Red Hat compatible kernel is based on RHEL source code. While you can run your full QA on Oracle Linux it generally is not necessary. What I typically hear from an ISV after doing such is “Wow, you guys are right, Oracle Linux is the same as RHEL, we will paper cert from here on out!”  You may not know this, but when it comes to Linux, Oracle only runs Oracle Linux on our infrastructure. We use no RHEL–zero, zip, zilch, nada. Because Oracle is so confident in our binary compatibility to RHEL, Oracle simply “paper certs” or says RHEL is certified for Oracle applications.

If you opt to certify your user space application on Oracle Linux with the Unbreakable Enterprise Kernel then you can deliver your application on the latest cutting edge, high performance kernel allowing ISV customers to ride the speed demon wave. Since the Unbreakable Enterprise Kernel uses the same user space libraries as our Red Hat compatible kernel, userspace applications certified on our compatible kernel are certified on the Unbreakable Enterprise Kernel.

Today I spoke with a large ISV who is certifying on Oracle Linux. In the last six months they’ve seen a huge demand for Oracle Linux requests and within the last few weeks have certified their kernel based application on both the compatible kernel and the Unbreakable Enterprise Kernel. This scenario is being replicated each week by large and small ISVs as demand is driving them to support their customers’ choice of running applications on Oracle Linux.

Oracle Linux has support from leading ISVs including:  SAP, EMC, HP, BMC, CA, Symantec, BeyondTrust, Microstrategy, Sungard, NetApp, Informatica, McAfee and Quest software just to name a few.

So now you want to certify on Oracle Linux, what’s the next step - who do you contact? Hit the comments section below and ask us to contact you, read our documentation, tweet us @ORCL_Linux or use good ole email with your request, and we’ll share with you how easy it is to certify. We make it easy.

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.

Q&A with Wim Coekaerts: Linux Turns Twenty!

We interviewed Wim Coekaerts, Senior Vice President, Linux and Virtualization at Oracle. Since we are celebrating 20 years of Linux this year, and Wim has been involved with Linux for a very long time, we thought it will be interesting to get his perspective on how Linux has evolved and what is next for Linux. Here’s what he had to say.

1. When did you first start with Linux?

 

I started using Linux in the early days. I do remember reading Linus's first mail while at school. My friends and I hung out in a computer room that had about 12 IBM PS/2 systems (386/sx) running AIX (at the time AIX 1.2 still existed on the ps2 as well). We were looking for source code for an OS and had actually put together, I believe it was, about $400 to buy the BSD source code tape from BSDI.

Anyway long story short, the BSD tape didn't arrive for quite some time and Linus's mail was perfect timing so we pulled Linux in and that was version 0.95+. First we replaced AIX with Linux on one PS/2 system, then more systems followed and after a while the entire PS/2 cluster became a Linux-based PS/2 cluster. Slackware was the first actual distribution that we then pulled in, tons of floppy disks... good times.

2. What changes have you seen from the early days of Linux to today?

Well, Linux grew up; it was a hobby project which turned into an obviously hugely successful software product. It's really quite amazing. It runs on so many chips/architectures, the download used to be a few 100K and now is 70M+ in size. Fascinating really. I think Linus did an amazing job by managing the project so incredibly well but at the same time allowing others to do stuff with a great amount of freedom. It prevented forks from happening early on. Many open source projects end up forking into different trees because people disagree but Linus has always managed to keep Linux as a nice single tree moving forward.

The other thing that changed is the number of people, the early days was a smaller group. However, even today, from what I can tell there still is a very similar core team that contributes to Linux often times still the same names.

3. How important is Linux in today's datacenter?

 

It's become a core technology, every datacenter probably has some amount of Linux running everywhere in the world. Whether it's a regular server or an appliance or embedded device. So it's everywhere. I don't think there's any particular place that Linux doesn't play a role in devices that need an operating system. Obviously the server market is visible a good use case but in terms of units the mobile space is way larger. People don't see that because it's hidden inside. I am sure everyone has some Linux running at home, even people that do not have a desktop computer but they have a Tivo or so.

This also implies that software is ported or built on Linux by most software vendors and that causes it to be a great ecosystem. It really is very pervasive today and that includes all areas, test and development systems, product systems, mission critical, clusters, etc...

 

4. How does Oracle invest in Linux and open source?

I want to highlight a few different areas here:

We port and develop most Oracle products on Linux and Solaris as a base-development platform. So by building products on Linux we obviously ensure that our customers can happily deploy on the OS. There is a big benefit to Linux here that often gets ignored or isn't really appreciated and that is testing. We have 1000's of servers running Oracle Linux that are used to test our various products. This helps test the OS as well, during our Oracle regression tests we run into OS related bugs, we triage and fix them. There are very, very few companies out there which such a large development environment and QA farm. QA is an important part for any product to improve and it's a great, underappreciated contribution.

Oracle started somewhere in late 1990s to port products to Linux, Oracle database 8.0.5 was first released on Linux in 1998.

 

We have the Oracle Linux development team which does a lot of contributions to Linux. Btrfs, all the Linux NFS work, a ton of SCSI work, etc. there's a long list of stuff that goes back into the mainline tree. There are two objectives for the Linux development team 1) Help make Linux a better OS in general. Features needed to continue to be competitive with other operating systems, Btrfs is a great example. These features might not always be related to what Oracle products need. 2) Find places where we can improve Linux to help run Oracle products better and faster.

This work started around 2001 and has been increasing ever since. The people in the team are part of the Linux kernel development community like any other kernel developers, same process, same way of working. It's very smooth and now that we have the Unbreakable Enterprise Kernel for Oracle Linux, we have a great vehicle to actually show this off more and we have the ability to get the work we do in the hands of customers directly. I believe this will help make people realize even more the amount of effort we put into Linux.

Use of Linux as a deployment platform. We have 1000's of servers in house running Linux, test, development and production just like we do Solaris. It shows that we are not just telling others to do this but also do it ourselves; eat your own dog food kind of thing! We also have, and continue to, offer Oracle Linux in our engineered systems such as Oracle Exadata and Oracle Exalogic.

 

5. Where do you think Linux is going to be in the next 20 years?

 

It's easy to predict the past, hard to predict the future! Clearly the mobile and tablet space uses a lot of Linux, so the embedded market is full of Linux devices, the server market is full of Linux servers and that will continue to grow. There are always new features to work on of course and as chips get more cores and threads and servers get more CPU sockets and memory scaling up will continue to be something to work on and improve.  I am not sure how well Linux on the desktop is going to evolve. People have been trying to predict that "this" is the year of the Linux desktop for quite some time now, tablets seem to be making inroads into that space to a certain extend, so maybe Linux's year of the desktop ends up being Linux tablets and mobile devices that are slowly replacing desktop use.

6. Now that Linux is twenty years old, I suppose Tux is twenty too!

Heh! Tux is timeless. As far as I can remember it has looked the same, hasn’t aged a bit!

 

Thanks for your time and insights, Wim. I’m sure our readers will enjoy reading this as much we enjoyed talking to you.
