DOAG noon2noon RAC & Dataguard – Quick Report

There’s always something to learn – for example about Oracle RAC (Real Application Clusters) and Dataguard. And the old-school frontal teaching concept is boring, and more important, ineffective after a few hours of passive listening. So the German Oracle Users Group DOAG organized a “noon2noon” event: “Oracle RAC and Dataguard” this week in Würzburg (January 2 1st-22nd 2016). It was the second noon2noon, after introducing the concept last year with Oracle vs. MySQL. I enjoyed it much last time, so I easily agreed to volunteer as a RAC Attack “Ninja” and tech guy on site for the workshops in general this year.

The response was close to overwhelming – we calculated 25 participants, but ended up with 39, and a PACKED room. Somebody called it a chicken cage, but the atmosphere was great. Thanks to the air condition. :)

Everybody is highly motivated, despite the packed room at noon2noon :)

But what’s that noon2noon thing?

12c jetzt Symposium Header

I had the privilege to continuously working on the 12c product evaluation and introduction from availability of 12c beta2 until today. My company, Performing Databases, played the key role for creating and developing the guidelines of operation, configuration and licensing. My example will be the “new” development environment, to show the first steps of the project. The highlight of the talk will be the report about our migration from 9i to 12c at S.Spitz GmbH, the biggest food vendor in Austria.

Chemnitzer Linux Tage 2015

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.

Martin Klier Oracle ACE

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.

O_ACEIcon_clr

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.

And I want to say thank you to three people, for all they do, think and say about me. These very special folks are Björn, Craig and Dietmar. I’m proud to call you friends.

My Oracle ACE program shipment just arrived today.

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.

Speaker at DOAG 2015 Datenbank – “Oracle Core für Einsteiger: InMemory Column Store”

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

2015-DB-Speaker-180x180

 

Abstract:

====================
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. ;)
Yours
Martin Klier

DOAG Noon2Noon Event Nürnberg / MySQL vs. Oracle – Review

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?
