It’s time! June 16th, the DOAG Database Conference takes place in Düsseldorf, Van Der Valk Airport Hotel. Twenty-two specialized talks about Oracle Database, Replication, Tools and Security promise a great techie-day. See the schedule of lectures here.
I’m looking forward to seeing you there, having great corner talks about Oracle, life and lemons, tweeting with hashtag #DOAGDB15 and enjoying this great environment the hotel provides.
I’m also glad and honoured to be on the list of speakers: “Oracle Core for Beginners: In-Memory Column Store” at 11am.
Take care and see you tomorrow!
On Thursday, April 23rd I’m speaking at DOAG BI 2015, the leading Oracle Business Intelligence Conference in Germany. (#DOAGBI15)
My contribution is: “Oracle Core für Einsteiger: In-Memory Columns Store”. The lecture will show, how the Oracle Database In-Memory option works “under the hood”, and how it is used to the best effect.
Please find the presentation here for download.
Looking forward to seeing you there, or discussing the presentation in the comments.
Last weekend, I had the chance to attend the Linux Days Chemnitz. It’s an annual meeting of the German Linux family with roundabout 2,500 attendees and a FANTASTIC atmosphere. It was two days of hearing tech talks, enjoying rich nerd content and talkin’ shop.
I feel VERY proud, honoured and grateful, that Oracle awarded me with the Oracle ACE in December 2014. The Oracle ACE program is a community reward, and encourages us to participate, enrich, promote and organise Oracle community events.
When speaking about the community, first of all I’d like to highlight my Oracle User Group of Germany, the DOAG (Deutsche Oracle Anwendergruppe). They are doing lots of nice, and educational things, lifting the fog, and practicing free and self-assured community work. Helping to spread this in our region, at conferences and events, is a pleasure. I’m very proud to be part of this great team.
A little less, due to the geographical distance, but with very similar motivation and experience, I feel connected and involved with the U.S. pendant IOUG (Independent Oracle Users Group). They are open for the international crowd, and it simply feels good to be there.
Just in case somebody cares, here’s my Oracle ACE profile.
I hope to keep up the level, and will continuously try hard to find the time to give back knowledge to the community.
The DOAG 2015 Database conference is on the horizon: June 16, 2015 in Düsseldorf, Germany.
I’m proud to announce my participation as a speaker, as I was honoured with in the years before. This year, my part will be a new “Beginners” talk in German: “Oracle Core für Einsteiger: InMemory Column Store”
Der Vortrag richtet sich an Einsteiger oder IT-Fachkräfte die nicht in Vollzeit als DBA arbeiten, jedoch Interesse an Datenbanktechnologie haben, bzw. für Entscheidungen hinsichtlich eingesetzter Technologien, Features und Lizenzen Anhaltspunkte suchen.
Der InMemory Column Store ist eine relativ neue Struktur der Oracle Datenbank 12c, und wird vom Hersteller massiv beworben. Der Vortrag möchte zeigen, wie diese sogenannte “In-memory Datenbank” konzipiert ist, funktioniert, und in welchen Szenarien sie sinnvoll eingesetzt werden kann.
I’m looking forward to seeing you there, for tech talk, hanging out and more tech talk. ;)
It was time to try something new in our DOAG Database Community. And please, please just not another frontal conference: twenty guys look forward, one looks back, like eight-oars-and-coxswain. I don’t know if DOAG invented it, but it was a success: The Noon2Noon Event.
How does it work? It’s like 24 hours of BarCamp, starting with a lunch, having a topic-of-the-day, lasting overnight, with winter barbecue, compatible for elders (thus, with Hotel and beds, no after-midnight hacking :) ). Ah, forgot to mention: One single talk being completely away from the topic, but somehow related to our work.
This first time, topic was “MySQL versus Oracle Database”. Johannes Ahrends and Oli Sennhauser as “headliners” ignited discussions about features, technologies and strategies known from Oracle, and how they are (or aren’t) in MySQL. And vice versa, but less. Participants came from all over Germany, plus Denmark and Switzerland. End users, consultants, technocrats, “boys” who go ahead and fail, and “girls” who test and succeed…
I greatly enjoyed the open format – listening, talking, drawing, discussing, swaggering, ignoring, pushing, pulling – the full repertoire. :)
From the technological aspect, it was great to learn something about MySQL – how consistent reads, clustering, and lots of other stuff works, that we never ever thought that it could be done different from the way the Oracle Database works. And that MyISAM isn’t the norm, but just another PITA. :) Go for InnoDB. What is MariaDB? And what the fork is Percona Server?
A while ago, DOAG.tv interviewed me about Oracle’s Standard Edition and database system migrations. The material was published just recently, so I’d like to share it. Enjoy, and if there are questions, just let me know!
I have to add a corrigenda: SE RAC is not – at least not at the moment – limited to a number of nodes. It’s currently limited to CPU sockets, to be exact, 4 of them. So a four-node SE RAC is possible, if I did not completely misunderstand the licencing policies.
Disclaimer: Licensing and pricing here are my OPINIONS, and not a reliable source to make decisions or confront Oracle with. :) If you need some tailored licensing information, feel free to email info-at-performing-db.com for advice.
my #DOAG2014 presentation and whitepaper are online now!
“Oracle Core für Einsteiger: Datenbank I/O”
Thank you all for attending!
It’s time for all Oracle folks to congregate in Nuremberg for DOAG Konferenz 2014!
I’d love to meet and greet you there – maybe you are also interested in my talk for Database Rookies: “Oracle Core für Einsteiger: Database I/O”:
Hope to have a great week with you!
