COLLABORATE 19 is a wrap – download presentations

It was awesome again – meeting so many people related to Oracle in USA. This year, COLLABORATE 19 (#C19TX) took place in San Antonio, Texas. For me the first time not in Las Vegas, it was a nice change.

Again, I was honoured with two presentation slots about Oracle Database technology. “Oracle Core – Database I/O” and “YOUR machine and MY database – a performing relationship!?”

If you are interested in my presentations, feel free to download them here. Thank you everybody who attended!

OBUG TechDays Belgium 2019

The TechDays Belgium 2019 were a great success – so many cool and nice people, and very interesting content. I’d like to say Thank You to the attendees, speakers and organisers – I’ll love to be back in 2020 if possible.

Here is the download link for my presentation “Performance is Rarely an Accident” in English.


And here we have some pictures from the event …

Download presentation “Oracle Core: Database I/O”

After talking at DOAG Conference 2018 and IT Tage Frankfurt 2018, the slides for the sessions are available now. Download presentation “Martin Klier – Oracle Core: Database I/O” now, and let me know if there are any questions, any time!

Abstract

We know different IO types that are used by the database. The DB needs them to fulfill its tasks. This lecture shows how and where they are different, and explains the advantanges and disadvantages of each. We will talk about access to tablespaces, online/archived redo logs and different file types connected to the instance.

I’ll include a quick review on the respective functions in the RDBMS, and we will also have a quick look into Oracle’s Automagic(?) Storage Management ASM.

I’d like to promote understanding of mass storage operations in the modern world, and transfer knowledge for a competent storage sizing.

In April 2018 at COLLABORATE18 in Las Vegas, our newly-promoted Oracle ACE Director Martin Klier had two sessions in the IOUG forum.

Both presentations are available for download now:

Full Throttle: Oracle SQL Tuning & the Ressource Consumption Approach

SQL Tuning Analysis for DBAs (DOAG 2016)

Picking out, validating and improving slow or resource-eating SQL statements is part of any responsible DBA’s work who takes his/her job serious. Identification alone can be tough, but it will be even harder to improve something you have no chance to understand the purpose of. This way, you will never be in the position to improve elapsed time by factors of 1 million or 100.000 – that’s a privilege of the designers and coders. But there is a generic way for us database whisperers to approach bad-behaving SQL, and improve it by factor 2, 5 or 10. Sometimes this is all we will get, so let me show you how: We are avoiding expensive tools, voodoo features, concatenated heuristics and one-engine-fixes-the-other. An unspectacular, real-world, common-sense approach, reaching the goals with grassroots technology.

Objective 1: Understand the basic components of parsing SQL in Oracle Databases
Objective 2: Pick the culprit, understand its execution plan
Objective 3: Weed them out, avoid collateral damage.

9th Software Performance Meetup Presentation Download

Thanks to everybody who attended the 9th Software Performance Meetup!
That’s the slides to “Performance is rarely an accident” as delivered by Martin Klier on September 27th 2016 in Munich.
Download here

Performance is Rarely an Accident

About the lecture:
The intention is, to show development teams, administrators and analysts, how beneficial it would be to think about performance at all, and that you’d need code instrumentation (=runtime meta information about application behavior) to get better. Martin will go from general Excellence over costs and implication of changes to the real craftsmanship of performance analysis.


We will keep you up to date
