Guest Post: Bruno Lima, Red Hat Certified Professional of the Year, EMEA

by Bruno Lima

Becoming EMEA’s Red Hat Certified Professional of the Year was very easy. I just wrote a letter and crossed my fingers, haha. Jokes aside, I believe I became a Red Hat Certified Professional of the Year because when I entered my submission, I not only wrote a reply, I relayed how Red Hat is integral to both the story of my life and in my career. From the innovative projects I’ve participated in to the satisfaction of our customers, Red Hat has meant a lot to me.

I started using Red Hat technologies in the mid-90s when open source was still unknown by many and ignored by almost everyone. I remember my first installation of Red Hat, which was at a public company in a small town called Sao Luis in Brazil. It was where I was born and raised. The company needed a reliable solution to run an electronic mail system, and at that moment the only platform that met our needs was to use the Red Hat Linux with Sendmail. I never stopped using Red Hat technologies after that, using Red Hat and open source for more and more projects.

Updates to the Red Hat Enterprise Clustering and Storage Management course

by Wander Boessenkool (Red Hat)

With the release of the updated Red Hat Enterprise Clustering and Storage Management Course (RH436) for Red Hat Enterprise Linux 6 a couple of new subjects have been introduced, while others have been updated to reflect the changes in the Red Hat High-Availability Add-On moving from Red Hat Enterprise Linux 5 to Red Hat Enterprise Linux 6.

One of the most noticeable new subjects in this updated course is the inclusion of an introduction to highly available, distributed, scalable storage using Red Hat Storage Server. Other updates include the use of multipathed storage throughout the course, as well as coverage of the XFS® file system.

Guest Post: Sean Millichamp, Red Hat Certified Professional of the Year

by Sean Millichamp (Secure-24)

Being chosen as the worldwide Red Hat Certified Professional of the Year has been a bit surreal. It has been an incredible honor and fantastic experience, especially being at the Summit this year. One of the questions I have been asked over the past few weeks is, “Sean, how did you do it? How were YOU the one chosen as the RHCP of the year?” The easy answer is that I wrote an essay and they chose me. But I believe that the real answer at the heart of things is open source, the community and many years of experience.

My first introduction to Linux in 1993 with Yggdrasil LGX was a spectacular failure. I’d found Yggdrasil for $10 at a local computer expo and bought it because I thought it would be neat to learn something about Unix. It lasted maybe a week and then it was off my system and forgotten. I couldn’t get networking to work. I couldn’t get X-Windows to work. I barely knew how to list files in a directory. What went wrong? I could point to a lot of things but my main trouble was the lack of hardware support and my complete lack of Unix skills. In retrospect, the biggest failure was that I had no idea about the Linux community out there (and without an Internet connection, I had no way to access it).

Checking in with Quint Van Deman, 2011 RHCP of the Year

It has been a little over a year since Quint Van Deman was named 2011’s worldwide Red Hat Certified Professional of the Year. Out of 600 submissions, Van Deman, an RHCA and director of open source consulting at Emergent, stood out with his experience helping clients move from last-generation, proprietary IT infrastructures to next-generation architecture that embraces the synergy of open source, open standards and cloud-based solutions. With the next winner set to be awarded on June 28 at Red Hat Summit in Boston, we wanted to catch up with Quint to hear the story that won the title, what he’s working on now and how his past year has been.

So, what story did you submit to win the award?

What I really wrote about was my journey to becoming an RHCA and how that really benefitted my professional endeavors. The journey to becoming an RHCA really exposes one to the breadth of solutions that are out there in the Red Hat stack, and how those solve organizational challenges. I was very clearly able to take some of those direct lessons and apply them out into my work. Also, how the RHCA really provides what I call the ‘instant badge of credibility’ when I walk in somewhere. A lot of time when you go into an organization as a consultant, there’s a lot of what I call ‘technical chest-bumping,’ where there will be someone in the room whose only objective of the meeting is to prove that they are smarter than you. Having that RHCA up there really defers a lot of that, especially with folks in the room that may have taken a Red Hat exam.

Tip/Trick of the Month: Using Highly Available Clusters with Red Hat Messaging

by Bruce Wolfe (Red Hat)

Red Hat Messaging (RHM) is built on top of the AMQP wire-level protocol, and is designed to be inherently reliable. However, if you have the resources, you can make your messaging application more robust with the addition of High Availability (HA) Clustering.

To set up a simple cluster you will need to edit three files, and populate the same values across each RHM broker and/or RHEL host instance:

/etc/corosync/corosync.conf

In the totem section add the network bind address (bindnetaddr), multicast address (mcastaddr), and multicast port (mcastport). For example, respectively: 192.168.10.0, 224.0.0.10, 5430

/etc/corosync/uidgid.d/qpidd
