IT Tage 2015 - "Analysing and troubleshooting Parallel Execution" presentation material

Thanks to all attending my presentation "Analysing and troubleshooting Parallel Execution" at the IT Tage conference 2015 in Frankfurt, Germany. 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.

If you are interested in more details I recommend visiting this post which links to many other posts describing the different new features in greater depth.

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.

UKOUG 2009

I'll be giving two one hour presentations at the upcoming UKOUG conference 2009 at Birmingham (30th November - 2nd December):

1. Monday, 30th November, 16:00-17:00: "CBO fundamentals: Understanding the different modes of System Statistics"

2. Wednesday, 2nd December, 11:05-12:05: "Everything you always wanted to know about FIRST_ROWS_N but were afraid to ask"

Both presentations cover fundamental functionality of the Cost-Based Optimizer which will help you to better understand why and how the optimizer comes up with certain execution plans, and in particular how the underlying cost calculation works. So eventually, if you haven't got an explanation yet I'll show you what the "cost" calculated effectively means and how to appropriately use the different optimization modes (ALL_ROWS, FIRST_ROWS, FIRST_ROWS_n) available.

So if you happen to attend the conference I'm looking forward to meeting you there.

By the way, I recommend visiting this link and save your personalised agenda to help with the room planning.

SIOUG 2009 conference

I'll be presenting at the SIOUG 2009 conference that will take place in Portoroz, from 20th to 23rd September 2009.

The title of the presentation will be "CBO fundamentals: Understanding the different modes of System Statistics" and will be based on the series already available here on my blog.

So if you're interested in the details of the cost calculations performed by the recent releases of the Cost Based Optimizer and would like to here about this in a different style, this presentation might be something for you.

If you happen to be at the conference I'm looking forward to meeting you there.

Thanks to OakTable fellow Joze Senegacnik for inviting me to the conference.
