Things Every Oracle DBA Needs To Know About The Hadoop Ecosystem (slides)

, ,

This is the deck for a presentation I had the pleasure to present in multiple forums over the last year. It’s a short introduction for Oracle personal (DBAs and DB Developers) to the Big Data challenges and solutions. This presentation is focusing on the Hadoop Ecosystem but also shows other solutions – such as Apache Spark.

This is things every DBA needs to know, and not EVERYTHING a DBA needs to know. This is only an introductory to the subject. I also have a 200+ slides deck for getting the in depth view. If someone find this interesting and want to read more, feel free to contact me and I’ll post the longer deck as well.

In the agenda:

  • What is the Big Data challenge?
  • A Big Data Solution: Apache Hadoop
    • HDFS
    • MapReduce and YARN
  • Hadoop Ecosystem: HBase, Sqoop, Hive, Pig and other tools
  • Another Big Data Solution: Apache Spark
  • Where does the DBA fits in?

This presentation was presented in BGOUG 2016, ILOUG Tech Days 2016, HROUG 2016 and DOAG 2016 Oracle user groups. I also presented this in smaller, more private sessions.

OOW2016: Exploring Advanced SQL Techniques Using Analytic Functions (slides)

,

This is the presentation I used for the Oracle Open World 2016 – it’s about SQL and more specifically about analytic functions and other advanced techniques.

Oracle Open World was one of my biggest aspirations for a very long time. Ever since I become a junior DBA I’ve heard of this conference but never thought I’d actually get to speak there.

For the last 3 or 4 years, I’ve been submitting my papers to the Open World CfP – and was never accepted.

Last year, I started to make my appearances at the different user groups meetup in the EMEA region. In June, I had the pleasure to sit down and talk to few user group leaders. From them, I learned what I can do better in submitting my papers and what kind of session I should aim for.  I followed their advice and indeed, I was accepted to present at the Open World (on the User Group Sunday – which, in my humble opinion, is the best day of the conference – with little to no marketing agenda).

So without feather ado, here it is. My first presentation at the Oracle Open World ever. The topic was Advanced SQL Techniques (analytic functions, grouping function and so on). This presentation also present couple of Oracle 12cR1 new features (since 12cR2 went out after OOW).  This is part of a bigger presentation I usually  give in a full day (I will post it as well soon) – that presentation also include newer features from 12cR2.

Presentations-Presentations-Presentations

, ,

For the last few months I’ve been presenting a lot in various venues. I presented in Oracle Open World, HROUG conference in Croatia, DOAG in Germany, Oracle Week in Israel (3 day long presentations!), MySQL User Group in Israel and in some more private conferences and private events. I was also accepted to IOUG collaborate in Las Vegas in April and I’m planning to give some Webinars soon.

I believe that educating and sharing is pretty important, and since most of my presentations are in English (the slides, but sometimes also the session itself) – I usually keep the habit of uploading it to my SlideShare for people to enjoy it.

I was talking to a customer-friend yesterday, and he told me that he’s been reading my blog for a very long time, but he’s kind of sad he can’t see all my decks there. So, I’m taking his advise and for the next few days, I’ll post all of my presentations here – a post for each of the presentations and will add the demo scripts, wherever applicable.

Feel free to ask questions and make requests – I’d love to hear you opinion and suggestions!

All of the presentation are available for download from Slideshare.

Oracle Week 2015: Oracle Advanced PL/SQL Presentation

, ,

As I said in my earlier post about Oracle Week 2015, this is one of the biggest database related educational (non-sale oriented) convention in Israel. None of the session is designed for selling any products (but consultant use it to showcase their abilities hoping to sell some professional services :)). Yesterday was my second daylong session in this convention this year . This time we talked about advanced features in PL/SQL and some new features of Oracle 12c.

Oracle Week 2015: Oracle Database Advanced Querying Presentation

, ,

Oracle week is one of the biggest Oracle related events in Israel which has going on yearly for the past 22 years (!).
It’s a 5 days long event with about 2000 participants in total over 80 different day-long seminars.
The seminars are around 8.5 hours (9am to 4:30pm) and are basically a day long course on various Oracle technologies which is nothing like the 45-90 minutes sessions I’m used to in the OUG sessions.

oug_scot: Oracle DB In Memory Presentation

,

This is the presentation I gave at the Scotland OUG back in June 2015 (Yes, I know I’m late).

The presentation was interrupted by a fire alarm (you can read all about it here).

This is a customer case study on a proof of concept we did with a customer a while ago. The PoC was successful and we are now waiting for the application to catch up and go to Oracle 12c so we can implement it in production environment.

I would like to thank the guys at Clarizen for allowing me to present their test case and to everybody who came to hear me talk.
