I have a bone to pick with UKOUG. I’m coming from Birmingham and I’m a lazy git, so why the heck am I on in the first slot? It was a 04:30 start to the day, for a train journey starting at 05:50. I could have got a later train, but it would have been busier and more importantly, more expensive… After putting the latest of my writing tips posts live and lying in the bath (sorry for the bad mental image) for a while psyching myself up for the day, it was a quick taxi ride to the station, then on to the train. The train was reasonably busy, but I had reserved a seat with a table and power socket, so I was able to use the time to write up a blog post about yesterday’s Oracle Midlands Event #9 and to do some last minute run throughs of my talk.
Since I was up in the first slot I missed the opening greeting to set up. The event was very Exadata-heavy and I was doing a virtualization talk, so I wasn’t really expecting anyone to come, but I had a pretty good crowd, which was nice. Many of the people in the room were already working with virtualization, some as users of the services, others as administrators. I don’t think there would be a lot that was particularly new to this audience, but I’m hoping they found at least something useful in there. After the session, I stood outside the room chatting to one of the guys about the issues he was currently going throught relating to Oracle licenses on VMware. It can be difficult, especially when there seem to be a lot of people out there actively trying to throw a you bum steer. My statement on this matter is always, only ever deal with Oracle Licensing Management Services directly, not sales people, which working this stuff out and make sure you have everything down on paper before you start!
I only managed to catch the tail end of “Oracle Exadata Meets Elastic Configurations” by Svetoslav Gyurov so I will have to assume it was totally awesome! I love you Sve!
During the session changeover, I got to speak to some of the folks on the Red Stack Technology booth. I popped by to say thank you for taking over the sponsorship of the Oracle Midlands events. They were also a sponsor of the UKOUG Systems Event itself, so a double thank you was in order.
Next up was “Oracle Exadata & Database Memory” by Frits Hoogland. Exadata is “posh-RAC”. Lots of stuff about RAC databases are also common to singe instance Oracle databases. As a result, this sesison was actually relevant to single instance, RAC and Exadata. Frits is one of those deep-dive guys, but the session had enough top-level and deep-dive content to appeal to all tastes. I really enjoyed it.
Next up was Roger MacNicol speaking about “Oracle Big Data SQL”. I had seen a bunch of this information last year at Oracle OpenWorld, but it also included some architectural information that was new to me. I was unaware of the architectural similarities between implementing smart scans in Exadata storage cells and getting Oracle to talk to Hive and HDFS. Very interesting!
I went to see “Migrating To Exadata The Easy Way” by Martin Bach because I wanted to watch him present. I don’t see working on Exadata in my future, so that aspect of the talk was not my focus. As with Frits’ session earlier, most of the content was relevant to Non-Exadata and Non-RAC environments too, so there was something for everyone here. Migration to new hardware and operating systems, no matter what the kit, comes with a similar set of issues and constraints. It also sparked some interesting discussions after the session, which meant I missed Jason Arneil‘s session on “Engineering DBaaS At Large Scale”. Hopefully I’ll get to see that at UKOUG Tech15?
There was a panel session at end the day. It is fatal to ask me to get involved in these things as I have an opinion on everything and find it impossible to keep my gob shut! I did warn them!
I spent much of the social event talking to @DBASushi about Enterprise Manager Cloud Control. I made some comments about Cloud Control in the panel session, which he wanted me to clarify. I’ve said before, I think all organisations should use Cloud Control, but there are some things about it I find infuriating, totally unintuitive and bloaty. During the discussion it became aparrent that some of my issues are because I need to RTFM a bit, but others are (in my opinion) problems with the user experience (UX) of the product. No offence to anyone involved, but some parts feel beautifully crafted, while other parts feel slapped together.
From there is was a quick goodbye, then off to Euston to catch my train home. Once again, a reserved seat with a table and power socket. Happy days!
