DOAG Red Stack Magazin Artikelreihe "Oracle Database Cloud Performance" (German)

In der aktuellen Ausgabe des für Mitglieder der DOAG, SOUG und AOUG kostenlosen DOAG Red Stack Magazins wurde der erste Teil meiner zweiteiligen Artikelserie "Oracle Database Cloud Performance" veröffentlicht.

Die Artikelserie basiert auf den hier bereits publizierten Erkenntnissen in diesem Bereich und führt diese weiter fort.

Der erste Teil geht auf die verschiedenen Aspekte der maximal erreichbare Performance ein (CPU, Storage etc.), der zweite Teil wird in der nächsten Ausgabe zu lesen sein und legt den Schwerpunkt auf die Konsistenz der Performance, also wie konsistent sich die Datenbanken in der Cloud in Bezug auf Performance während der Tests verhalten haben. Interviews (German)

In den letzten Wochen sind zwei Interviews veröffentlicht worden, die die DOAG mit mir im Rahmen der jährlichen DOAG Konferenz in Nürnberg durchgeführt hat.

Das erste stammt noch von der DOAG Konferenz 2015 und bezieht sich auf meinen damaligen Vortrag über die neuen Parallel Execution Features von Oracle 12c: Interview 2015

Das zweite ist von der diesjährigen DOAG Konferenz und bezieht sich auf meine Performance-Tests der Oracle Database Cloud und dem dazugehörigen Vortrag: Interview 2016

Thanks to all attendees that came to my presentation "Oracle Database Cloud Performance" at the DOAG conference 2016. You can check the presentation material here at Slideshare.

DOAG 2015 - "Oracle 12c Parallel Execution New Features" presentation material

Thanks to the many attendees that came to my presentation "Oracle 12c Parallel Execution New Features" at the DOAG conference 2015. You can download the presentation material here in Powerpoint of PDF format, as well as check the Slideshare upload.

Note that the Powerpoint format adds value in that sense that many of the slides come with additional explanations in the notes section.

DOAG 2012 Conference

This is just a friendly reminder that I'll be talking at this year's DOAG Oracle conference about "Cost-Based Optimizer Basics" on Thursday, the 22nd of November, "Raum 1" at 13:00.

Additionally, I've reserved a slot at the "Unconference" (15:00 the same day) where I plan to present some of the interesting stuff that I cover as part of my "Parallel Execution Masterclass".

And soon the technical content will be back at this blog where I have lots of interesting stuff in the pipeline, mainly covering Parallel Execution topics.

DOAG 2012

This year again I'm going to present at the DOAG 2012 conference in November. Since it is a popular topic I decided to talk about "Cost-Based Optimizer Basics" there, too. According to the official schedule the presentation will take place on Thursday, the 22nd of November, "Raum 1" at 13:00.

Like last year, I'll also try to do some Unconference sessions in addition - if it is going to take place, which I don't know yet.

I'll post some updates as soon as I know more details.

(Virtual) Public Appearances - Free Webinars

I'll be presenting at two upcoming webinars:

1. "Oracle Cost-Based Optimizer Basics" hosted by on Wednesday, 11th April 2012 16:00 (UK Time).

In this session I'll explain the key concepts that influence the decisions of the Oracle Cost-Based Optimizer most. If you want to understand the key concepts about how to write efficient queries and why the optimizer sometimes might not come up with a reasonable execution plan, then this session is for you.

Note that the webinar is free and registrants will receive a recording afterwards. Here is the link to the official landing page. Thanks to for hosting this session.

Here is an abstract of the session:
