Why I love the German, Austrian and Swiss customers – a DOAG 2022 conference recap

Wow – this was a tough week in Nürnberg at DOAG 2022 Conference. It started with a lot of rain. And I mean RAIN. Luckily I packed my umbrella last minute before going to the train station. But before I tell you a bit about this week, and why it was so incredibly important to be at DOAG 2022, let me tell you at first why I love the German, Austrian and Swiss customers –  a DOAG 2022 conference recap.


At first, a big THANK YOU

And before I write something about “my” week, let me give a

DOAG Conference 2022 is next week already

I’m scared – time flies so quickly. Yesterday evening I returned from vacation, and this morning I spoke to Daniel and we both realized: There is only one week to go since DOAG Conference 2022 is next week already. Yes, in September 2022. Not as usually in November – September it will be this year. And we hope to see you there next week in my hometown, Nürnberg for another great DOAG conference.

OC YATRA Tour 2022 – It was a blast. Or: Why conferences are so important

OC YATRA 2002 – India, Begaluru, Sunday, July 24, 2022

How did it start?

Months ago, Sai Penumuru and the AIOUG organizers asked whether I’d be willing to come to India for the 2022 Oracle Community YATRA tour. The last time it happened – before the world knew about Covid – Roy was traveling and doing part of the …

DOAG21 – Oracle Multitenant Migration – Deep Dive and Secret Secrets

Regardless whether you migrated already to the CDB architecture, or you plan to migrate to Multitenant soon, this talk will shed some light on the not-so-well-known aspects around Oracle Multitenant. We assume that you know already quite a lot. Our focus will be on not obvious features and typical issues you may face when you migrate your well-maintained non-CDB into a PDB. Gotchas, secrets and workarounds are the things we’d like to share with you. Your next migration will become a success – but we’ll better discuss also the fallback. Ah, you have a Data Guard. Ok, we may …

DOAG 2019 – Recap and a personal complaint

Nürnberg and München are just 175 km away from each other, a bit more than 1 hour by train. Still I felt a post-conference blues already when I boarded the ICE train yesterday to head back to the south. It was an awesome conference – again. Except for one thing which I will write about below. So here’s my report on DOAG 2019 – Recap and a personal complaint.

DOAG Conference – Recap

This year’s 2013 conference was the best DOAG Conference I have attended so far (and it was my 11th conference).  Actually due to the fact that I’ve had just one presentation (Working with Oracle Multitenant in the Real World – thanks to everybody coming by in the huge TOKIO room – that was really fun!) and a DOAG TV interview I’ve had enough time to see some other presentations. I did actually enjoy the Oak Table Stream in room SHANGHAI a lot – so many good stuff, I have really learned a lot.

So thanks to the organizers from …

DOAG – German Oracle User Group Conference

This time I had only one presentation at the DOAG Conference in Nürnberg (actually that’s my hometown so it’s always great for me to be there).

And – as always – it was great to meet all the Oracle users again. For me that’s the best opportunity to get in touch with customers I know for a looooong long time, Oracle colleagues from Germany – and even some US colleagues such as Hermann Baer, Markus Michalewicz and Tom Kyte presented as well. Sometimes you feel like being at a big family event 😉

And thanks to those you stayed for …
