Friday Philosophy – Doing DOAG (& a Little, Light, Hem-Touching)

This week I’ve been at annual DOAG conference. DOAG is the German (Deutsch) Oracle User Group annual conference. It’s my second time there and I very much enjoyed it, meeting lots of people & seeing some great talks. I also got a request to do more Friday Philosophies, so…

DOAG is now the biggest Oracle User Group conference in Europe, it overtook the UKOUG conference a few years back. Do I see this as “competition”? Well, a little bit of me does because for several years I was involved in organising the UKOUG tech conference – and a part of me would like “my” conference to be the biggest. But that is just misplaced, juvenile pride – really there is no competition between us. DOAG caters to the German Oracle User community (and nearby countries), UKOUG to the British Isles and, to a certain extent, Ireland and the closer parts of mainland Europe. If there is any competition then it is for presenters. I know that sometimes presenters have had to pick between the UKOUG and DOAG as they can only manage so much time doing these thing. But I also know many presenters who do both. Also, both conferences are lucky enough to receive many more, very good presentation abstracts than they have presentation slots for. There will always be a great selection of presentations at both conferences.

There are some aspects of DOAG that I really do wish we could replicate for UKOUG. The first is the venue. Not only is the space they have at the Nuremberg conference centre so much larger and and better suited than the ICC in Birmingham, but it costs them “a lot less”. It might be outside of town (and Nuremberg is a nice town) whereas the UKOUG conference is almost in the middle of Birmingham, but at DOAG you get free transport as part of the conference pass. The second is the catering. The food at DOAG is very, very good; coffee is available at all times; you can get real, decent coffee from some places (in the UK you need to go find a place that will sell you decent coffee); DOAG end the conference with beers and light snacks – the UKOUG conference tends to fizzle out.

But for me, though it is a close-run thing, I do ever so slightly prefer Birmingham and the UKOUG conference. I find it a little more relaxed (certainly there are less suits in evidence) and, on a personal level, I know so many more people there. I like knowing where the pubs & restaurants are and which ones are terrible! And somewhat ironically, our German Christmas Market is not only in full swing during the conference, but it is bigger than Nuremberg’s. But how many wooden toys, Gluhwein and sausage do you need in your life?

I did have a somewhat bizarre time with my presentations at DOAG though. First, I had to cancel a presentation. I was preparing a new one on the philosophy & process of performance tuning but due to some back pain issues (or rather the impact this had on my sleep and the pain medication had on my brain) I was utterly failing to get it done. So with only a week to go I had to ask if they could replace me. I hated doing it so late, I know what it is like organising these conferences and losing talks when you have printed the agenda is a real pain. Plus you now need to find a replacement. But I also know they would not appreciate a poor talk, so I let them choose. They chose to drop the talk.

But I honoured my other two presenting slots. The first was at 11am the first day and I experienced that thing that most presenters secretly like – it was so popular there was only standing room! As a result, the DOAG organisers asked if I would repeat it the next day or last day. Of course! However, as it worked out, they asked me to repeat it later that afternoon as one speaker was lost in transit. There was of course no time to really advertise the change. So I repeated the talk 4 hours later in the largest auditorium I have ever presented in – to 27 people. They of course were scattered around the room like lost souls. I guess it was using a room that would otherwise have been empty, and the session was recorded I think. But it did feel odd.

In between these two talks, I saw a couple of other people present. And in one talk, my phone kept buzzing. That was unusual, especially as it was a German number. I eventually exited (from the front row) and took the call. It was DOAG! They wanted to know why I was not at the interview I had agreed to do. “Because that is on Tuesday!”. Pause. The confused lady on the phone said “Yes. It IS Tuesday…” *sigh* – did I mention the pain meds and my brain? That was embarrassing. I had to go back into the room, to the front, get my stuff and wave an apology to Chris Saxon & Heli Helskyah before scuttling off to this interview. Which I did very badly.

My final talk was interesting for other reasons. The talk was on calling PL/SQL from SQL and the impact it can have on performance and the point-in-time reliability of the results (if your called PL/SQL function itself runs SQL). I’ve discussed this topic with Bryn Llewellyn, the product manager (distinguished no less) of PL/SQL & EBR, in the past and I was able to catch up with him just before the talk. Then he came to my talk. I’m presenting in front of the Oracle employee who owns the tech I am talking about. No pressure. Then I look around the crowd and it is liberally scattered with other senior Oracle technical people, OakTable members, Oracle ACEs…

This is an unappreciated, small problem with becoming friends with these people. The bas…. good fellows and ladies come to your talk – and heckle.

Well, it keeps me honest and the heckling that did inevitably happen was all good-natured, and corrected a couple of slightly weak bits of my talk. So the crowd got a better talk than they otherwise would have.

And the Hem Touching? Well, go back a few years and we did not have the breadth and diversity of information the web now provides for us. In fact, we are talking back in the 1990’s when there was nothing like google and blogs and Oracle Base. What information was out there for Oracle was much more paper-based (you know, actual books & magazines!) or the odd word document that was emailed between people. One name I saw on such things quite often and who taught me an awful lot back then was Craig Shallahammer. Well, Craig was at DOAG, I’d seen him in the crowds once or twice. And after this talk he came up for a quick chat. I might have been presenting now for a good few years and met many of the best known people in our world of Oracle and I’m generally immune from the desire or need to go “Oh! You’re xxx! I’ve read all your papers!!!!”. But I did a little with Craig, as he was from my “Oracle childhood”. And he was very nice about it.

So all in all, an excellent few days. I’ll try and come again next year. Maybe if I finish that talk on the philosophy of performance tuning, they’ll let me do it?
