UKOUG Operating System and Storage Event : Summary


Today was the UKOUG Operating System and Storage Event. I was a tourist for this event, as I didn’t have any presentations to do. Added to that, I’m a grunt DBA, so I wasn’t too sure what would be waiting for me at an OS and storage event… 🙂

Thanks to the miracles of Google Maps, I managed to be late for the event, so I missed the first session. Why is it I can get to foreign countries on time, but I can’t get to something that is pretty much in my own city without getting lost?

I bumped into a few people I know there, including Jason Arneil and Martin Nash and a couple of my colleagues. 🙂

First up (for me) was “Patching Linux with Spacewalk and Ksplice” by Wayne Lewis and friends. Spacewalk looks kind-of neat. It’s a free open source product, with Oracle’s version of it available from Basically, it allows you to easily set up a local repositories, manage and track OS package updates across your Linux infrastructure. You can use it for free, or if you want you can choose to buy support from Oracle. The choice is yours. The second half of the session was on Ksplice, which I’ve known about for a long time. As it turns out, my understanding of what Ksplice actually does was quite off the mark, so it was good to be educated… 🙂

Second up was “Bringing OpenStack to the Cloud” by Stephen Bourke and friends. OpenStack is used to build public and private clouds. That is honestly as much as I actually know about it. 🙂 This session discussed what OpenStack is and talked about Oracle’s implementation of OpenStack. You can read more about it here:

What was most refreshing about Oracle’s implementation of OpenStack is they are keeping it open. At a time when other OpenStack vendors might be trying to provide ClosedStack, Oracle are staying true to cause.

Next up was “Dtrace in Linux and Solaris” by Mike Carew. I’m not one of those guys that spends my life using Dtrace, strace or systemtap, but occasionally you have to get down-and-dirty, so it is good to keep on top of this stuff. Some great strides have been made to bring Dtrace to Linux, but it is still quite limited in comparison to the Solaris implementation. Perhaps as it matures we might get a feature like this on Linux, which I learnt about for the first time today!

“Virtualisation Case Study – How Not To Do It!” by Philip Brown was interesting as it was almost the polar opposite to my feelings about virtualisation. In fairness to him, this was a presentation of how not to do it and ultimately he did make the point that if you do it badly you are going to have a bad experience, which is definitely true. My counter to this is, if you do it well you are going to have a good experience. 🙂 It’s all about using virtualisation where it is appropriate and knowing what you are getting into before you make that leap. Due to me not being able to keep my gob shut, there was a prolonged discussion about this topic after the session, which was fun. You can of course read my thoughts on virtualisation in this article.

I really enjoyed the day! Well done UKOUG and to everyone I saw presenting today. I certainly came away with a lot of good stuff to think about…
