Birth of a user group conference…


Or, how post-conference blues hit.

Seeding

You don’t actually get to witness these kinds of things to often. Yes, there was the birth of POUG conference, the passionate work of Kamil Stawiarski and the people he gathered around him. He did an awesome job and pulled it off.
Why then is this so special? Well, first of all because it is my native conference. People that have contributed for many years, working closely together with new members to create something new. I think it is kinda special.
Richard Olrichs, Ise Douwes, Luc Bors and Bart van de Laar formed the team that pulled it of! Kudos to them.

Work started already end of 2016… on the notion that this conference was being organized, there was a small Twitter bombardment to recruit as many of the interesting international speakers to come and join us. This helped create a fabulous agenda, covering 81 (!!) sessions and 3 keynotes over 2 days in the spectacular setting of “De Rijtuigenloods” in Amersfoort.

Importance for NL

We have (finally) done it! The Netherlands have experienced their very first Full Stack Oracle Conference ever! I have said this many times before, and I will say this probably many times again, this is so very important for the spread of knowledge, the exchange of experiences and cross-pollination between countries!
We have never done this before… We have APEX World, which is, of course, super important! And we have SIGs, which are very important for people working within a specialization. All good, all very important! But our business is way to specialized already. If you never take the time to look over your boundaries to what your colleague is doing (for which you don’t have time on a day-to-day basis) you’ll get isolated and miss out on possible great idea’s, changes and inspiration. For this alone, events like these are so important. For a country / region (as we span Benelux) that is so active in IT, it is a nuisance to have to go to either the UK or to Germany to experience a conference like this.

It is _that_ important…

One personal thing… nl.OUG (this is the brand new name for OGh, which also symbolizes a new start to me) focus on talks on (end-) user experience, in effect, partners with end-users coming to share project briefs… Good in itself, but not what I would applaud as main focus. These conferences – to me – are about learning and the best learning comes from professionals sharing either best practices or telling about technical implementations of technique. These stories are obviously always very welcome, but are no main focus…

My personal experiences

— International scene

As an active member of the Oracle community, I tend to know a number of people, spread out over this globe. One of the joys of a general conference is the fact that many of these people also participate. This leads to many happy encounters. With Oren Nakdimon from Israel, to Sandra Flores from Mexico, with Tim Hall, aka. Oracle Base, Maria Colgan & Brendan Tierney and therefor with Chris Saxon, more than 2rds of the Ask TOM-team!! And even many more famous speakers from home and abroad. It was a very special feeling to meet all these beautiful people on my home turf!

— Followed sessions

I didn’t get to follow many sessions, partly because of the many people I met and wanted to catch up with and partly because of, well, other responsibilities…
And perhaps a bit because of the fact that the ratio between serial sessions and parallel sessions was a bit off.
I did get to see:
The keynote by Maria Colgan highlighting the many things you can do with an Oracle database
Investigating the performance of a statement via the SQL Monitor report by Toon Koppelaars, which is always insightful!
Moving Oracle data in real-time – The 3 fundamental principles of Oracle replication by Jakub Sjeba from Dbvisit, which proved to be an excellent basis for my own session, later that day
Blockchain on the Oracle Cloud, the next big thing by Robert van Mölken, who helped me understand the technical side of the Blockchain technology.
It’s a wrap by Lucas Jellema, who did a great job at really zooming out and looking at the bigger picture.

— My sessions

I had the lucky opportunity to present even 2 sessions in Amersfoort.
Migrating your Oracle database with almost zero downtime
and
Comparing PostgreSQL to Oracle

Both sessions were well attended and interactive. I enjoyed it very much and, judging from the reactions and interactions, I guess the attendees too. Thank you for attending!!
Obviously I am happy to see the uptake of PostgreSQL and EDB Postgres in the Benelux. As said with “horses for courses”, Oracle has it’s playing-field, but so does PostgreSQL, and probably bigger than it is today 🙂

And now, the future…

This was 2017, this was the kick-off, the very first one.
With the buzz and with the post-conference blues…

It now is time to look to 2018, start preparing. Gathering lessons learned, inventorise feedback and make plans.
Whatever the outcome, there can only be 1 plan! “nl.OUGTech18″ or “Tech Experience 2018” we need to make sure the messages reaches further and wider.
With over 250 attendees for a first event, we aim for over 500 for the next event. There are more than enough potential participants in our region to pull this of.
The basic structure is there, the first succes is there, let’s do this!!

See you all next year!!
(or hopefully sooner)


Riga Dev Days 2017, new experiences in many ways.

Riga Dev Days 2017

General

It has been a while since my last blog-post.
One of the reasons is my shift from closed to open source software, databases more specifically. More on that in a later blog-post.

The reason for already mentioning this is this strange hybrid (what a popular word, these days) situation that I am in at the moment.
Thanks to the super enthusiastic, flexible and tenacious organization-team of the Riga Dev Days, I was able to participate.
Happily boarded the Air Baltic flight, I went on my way to Riga!!

Being new at the broader conference scene, I enjoyed being at a mixed source developer conference. Besides the usual suspects – some of which are my best friends – I got to meet many interesting new people.
One of the key phrases of the day is: “the more you learn, the more you realize you know nothing – John Snow…” and it’s true! You never stand to think about it, but the wealth of subjects is just tremendous and the combined knowledge at events like these is down right “Yuge, it’s awesome, tremendous!”

Day one

With a day like this, time flies. Between session (and during sessions) there are discussions, a bit of work and catching up to do.
Still I managed to catch a few sessions, like the one from Michael Hüttermann who made a clear and well rounded case regarding CI/CD in a DevOps world. A nice insight into the effort that goes into what’s behind the proverbial “push of a button”.
Another example was that by Marcos Placona about the many (and very basic) things that you have to keep in mind wen building apps. There is no silver bullet and the best you can achieve is to discourage the hacker so much, they move on. Much like securing your house, do to speak.

The day ended in the medieval basements of Riga, where we had some really good medieval food. Life is good…, well…, it has it’s moments!

Day two

The keynote address by Edson Yanaga, which kicked off day two of the Riga Dev Days, was quite interesting.
Shortening development and deployment cycles and shrinking feature release sets actually helps improving software and deployment quality by creating faster and more accurate feedback loops. By looking at these concept in this way, buzzez like DevOps and Agile actually get some hands and feet. One of the lessons, though, is that doing things this way do not eliminate work or automagically solve various issues for you! It will help in getting predictability and continuity into your software development processes.
A nice eye-opening remark finally, was… “no, I don’t pay you to make something work on your computer, I pay you to make something work on my computer(s)!!”

Another talk I was able to attend was around Blockchains. Something I knew nothing of and was actually quite interested in. Nick Zeeb took us through a very lively and very animated tour of what actually a Blockchain is and what the awesome potential of this technology can be. I was impressed.

With this, the second day draw to and end and therewith also my turn “in the pit”. As this event is held in a movie-theater, every room had a sloped tribune, which was often packed with enthusiastic participants. I had the opportunity to share my thoughts on the comparison between PostgreSQL and Oracle.
The session was very well attended with a lot of questions regarding the possibilities of using these other technologies in scales that were not really considered before. You can find a recording of the actual presentation here as soon as it comes available.

Riga Dev Days was a good conference. I would recommend everyone to either attend or submit an abstract for their event in 2018!!

#Oracle cutting in inspiration and new business?

Over the many years Oracle has been leading the database world, I guess they are now taking something of a wrong turn.
Let me briefly fill you in on my thoughts.

Basically I see two “minor” shifts that are significantly indicative of this:

  1. Oracle Standard Edition 2
  2. Oracle ACE Program

Okay, so you might think I am crazy, but let me try to explain.

Oracle Standard Edition 2

Sometime last year, the long expected, anticipated…, dreaded perhaps even, change to the Oracle database licensing strategy was there.

Oracle Standard Edition (SE) and Oracle Standard Edition One (SE1) licenses were addressed.
There was A LOT of debate on this, I mean, A LOT. Discussions which ran all the way back to HQ, and were driven by passionate people inside and outside of Oracle, inside and outside of the Oracle community… To no avail.

It had been very clear for quite a long time that the SE / SE1 strategy was nothing short of unsustainable inside the Oracle licensing realm. Even though, Oracle SE and SE1 enabled many projects and customers to adopt the phenomenal Oracle technology for their projects. It has some limitations, but with smart thinking and smart planning, a lot of projects could be run with Oracle SE(1). “I am such a good DBA, I can even do it with Oracle Standard Edition!”
Alas, we now have Oracle Standard Edition 2 (SE2) with a new and upgraded price of US 17k (!!) making this solution rather out of the question for many of the projects meant in the above. Please note that SE1 already was a significant investment for some of the projects I have learned to know over the years in regions as the Baltics and Africa.
Yes, of course, I know you can do all of this “In the cloud”. But with the limitation that there are hardly any CSPs (Cloud Service Providers 😉 that enable you to make use of the “cheaper” Oracle license. If you want to leverage your local cloud vendor (mind my word-choice here) it’s BYOL (Bring Your Own License) and, voila, you’re done in for anyway.

Hence, the first significant “shift” in Oracle’s span of attention for new business, creativity and growth…

Oracle ACE Program

More recently there was also a change in the Oracle ACE Program. Which has also led to much debate. But… that bit of the change I am not referring too, I am referring to the bit that does not affect me directly…

Oracle has a small number of very highly appreciated and “industry leading” community advocates called “Oracle ACE Directors”. These people not only have a deep knowledge of everything that is happening in this corner “of the industry”, but are also very passionate about sharing this knowledge. Sharing with Oracle Users, sharing with stakeholders within the Oracle organization, basically, with everyone with a hunger for knowledge around the technology.

For this, these Directors had a few privileges. When the invested their time and their energy in traveling this globe to share, Oracle would support them in some of their travel expenses. This always had the air of “wow, they are paid”. Believe me, it was bare minimal support, just a flying ticket and a hotel-bed to a previously approved conference, when they actually were accepted to do a talk. Nothing shiny, nothing business-classy…

Until now. With the changes to the system, also these modest privileges for the Directors have seized to be.

There was my second significant “shift” in Oracle’s span of attention for new business, creativity and growth…

It has me worried… I should not worry, as it does not affect my day-to-day business… yet.

Albeit we have this cool tech, with PL/SQL, with APEX, with all the features, options and what not, to create solutions that could really better the word (I also firmly believe this).

Oracle is just closing this door, and my toes were still in the doorway, so that hurts.

This was my rant, hope it helps.

#DOAG2016, definitely a crazy week.

#DOAG2016, the largest Oracle Community gathering in Europe. Taking place in Nuremberg, at the Nuremberg Convention Center NCC, one of the more impressive places to hold such a conference, towering 4 stories high, with a big central atrium!!
It is a huge effort to get all of this together!

In this blog-post I want to highlight some of the crazy things I experienced this week… And… I did try to follow my own schedule, but I wasn’t overly successful.

Young talent

One of the things that was somehow quite clear this week, is that we have a lot of young talent out there, eager to learn and share experiences. It is not just the #NextGen “movement” of DOAG, of which Carolin Hagemann made me aware, but just young people on the conference itself.

Discussing “Young PL/SQL” at the unconference session made us all aware that our part of the IT trade is no very sexy and popular with the youngsters. This all despite what was mentioned above. In universities we train SQL, but we don’t train to create real-life business applications, leveraging the power of the one language that keeps SQL close to the data it feasts on, PL/SQL. But, more on that below (Thick Database Paradigm).
To promote PL/SQL, basically two ground requirements were defined:

  1. Create a free ‘PDB as a Service’ for schools;
  2. Inspire teachers to talk about data centric computing

By finding somebody to be regionally or globally owner of this quest, it should be possible to get young professionals as familiar using PL/SQL for creating performant and business-ready applications as they were familiar using Microsoft Excel to do their accounting “back in the days”

ACE program

“There is a disturbance in the force!”

For everybody not acquainted with the Oracle ACE Program by the Oracle Technology Network… You should be!! Please read up, as it is an incredible cool initiative.

The disturbance, you ask?
Well, to retain your “status”, Oracle expects you to do “stuff” and this “stuff” is then evaluated on a yearly basis. Basically the initiative, the disturbance, is to get some transparency in “the stuff”. And, as always, everybody wants change, but few actually are good at “change”. There are rimples and things that change, but in the end; everything will be fine, unless, obviously, when it will not be fine.

Talks

I was honored to (co)host to talks at #DOAG2016:

Bad Boys of Replication – Changing everything…
With Oracle ACED and good friend Björn Rost, about an intense migration project we did some time ago. We were even offered to host our talk in Tokio, the biggest hall at DOAG!

Saving lives at sea at an industrial scale using Oracle Cloud Technology
An insightful (at least I like to think so) talk with my colleague Oliver Limberg. The talk is about the rapid development of a global portal for the maritime logistics branch.

I had a blast, and I hope you did too!

Community spirit

Oracle User Group conferences are about sharing and are about fun. Mr. Martin Widlake wrote a good post about that.

Apart from all the “more formal” things that happened, there were quite a few extracurricular activities, mostly involving an Irish Pub or a restaurant.

This all may sound quite funny and exciting, and, yes, it is alto talk with your co-workers: “Oh, hey, you are going to have fun and party all week!” Of course it is not a drag and a bore, but it has very profound function!
Whenever you run into trouble, these are the exact same people that are not only able, but probably also inclined to help you out, as you would help them out, as friends do among each other. In the end, they, you, your boss and your clients benefit. This is not to be underestimated too much.

The extra, special bit, that DOAG offers are the so called “unconference sessions”.
Not scheduled, no slides, nothing official, just getting together and discussing subjects of interest. Our “Young PL/SQL” was one of these “unconference session”, which turned out to be a great (and valuable) success!

Meeting people

Just to name a few, heroes of long and of yet to come for #DOAG2016:

Dietmar Neugebauer
Frank Dernoncourt
Joel Kallman
Johannes Ahrends
Kamil Stawiarski
Laurent Leturgez
Maja Veselica
Marcel Hofstetter
Piet de Visser
Sabine Heimsath
Stefan Kinnen
Stew Ashton
Uwe Hesse
Zoran Pavlovic
And alle the ones I forget to mention here!!

Thick Database Paradigm

Noting new in IT…

Well, no.

The Thick Database Paradigm (opposed to the “No PL/SQL Paradigm”) is nothing new. We have actually all been doing this since the eighties. Program your business rules, your constraints, everything that makes sure that your data is all that you want it to be, close to that data.
There are so many reasons that speak in favor of this approach that it is nearly overwhelming and deserves at least a book in itself. But, let me make a small attempt to highlighting a few here:

  • spare yourself network bandwidth, by not sending data all over your network to be processed
  • safeguard your data inside the (Oracle) database, so it can be protected by all that has been invented to do so
  • Transact data where it lives and combine and aggregate it there, you will be amazed by the efficiency
  • Remind yourself why you used to think “business logic in middle teer” was a good idea

If you leave possibile religious believes aside, there is no other conclusion possible then that the reinvention of “Thick Database” is the (re)discovery of 2016, right from the time when IT still made sense.

Yes, there are cases where an “Enterprise Service Bus” makes sense, but, as with every technology withing IT, it has a very specific area where it actually adds value or even makes sense. At best, a lot less than all the places where it is used currently!
Not to get carried away in this joyful blog-post, I will leave this topic at this.

The end

I hope to see you at the next Oracle User Group conference, somewhere… Please watch for the asterisk at his page for the conferences that I will attend.

#OOW16, San Francisco, looking back

In this post I just wanted to highlight a few things that have lingered with me since the 2016 Oracle Open World Experience.

Persistent DRAM
Now, here, being at home, I must admit that I cannot find very much documentation about this, but it got me thinking… A little paradigm-shift, where computers actually wouldn’t need moving parts anymore (ie. disks of any kind). Create devices that use these memory structures, quite possibly combined with flash-disks, to run entirely on RAM. The 3D XPoint Technology could be a nice example of this. I think I would applaud such machines.
I know, not a real export point I am making here, but if anyone has a better angle, I would love to read your comments.

Thick Database
This is a much better documented topic, much more tangible too.
Toon Koppelaars started this “new” approach with his talk at OTW16. You can review his presentation here and see the video’s of the presentation here and here.
I guess some really good points there. The creation of an application is a craft. You need to get the right materials and do a number of steps to get a solid foundation. Meaning you have to create a solid data-model (yes, even in the world of BigData, schema on write, etc.) most applications still rely on a data model and all that we were taught to go with that. Not much sense in repeating what’s in the presentation here though.
An eye opener and something to (re)consider!! I plan to talk about this a bit more later.

EBR & Oren
One of the best sessions I visited during OOW16 was the presentation by Oren Nakdimon accompanied by the illustrious Bryn Llewellyn.
The presentation discussed a true implementation of CI/CD using some of the capabilities of the Thick database paradigm as discussed above, combined with the possibilites that Edition Based Redefinition brings.
Using these technologies, Oren has been able to implement a rolling upgrade scenario for Moovit. I find this impressive.

Philippe Fierens & SPARC
I had the honor and pleasure of working closely together with my good friend Philippe Fierens during this edition of OOW. It always adds a dimension if you are able to tackle some of the challenges of the week as a team! Thank you Philippe.
Though Philippe I am also affiliated to the continuing efforts to build and maintain the Oracle SPARC architecture of which he is a strong advocate. Be sure to follow his blog to learn about the latest developments in this area.

Panel discussions on the last day
Saving the best for last… Literally!
On the last days there we some panel discussion regarding SQL / PLSQL and application architecture. I found these discussions to be quite meaningful and the interaction with the attendees was grand. Having people like Chris Saxon, Connor McDonald, Toon Koppelaars and Carry Millsap on a panel, there is no way you can go wrong!

OTN & a bow
Finally, looking back at this OOW, it was actually the first one I visited as a member of the OTN Oracle ACE community.
Boy, does that make a difference in how you experience Oracle Open World!!
Of course, you can chill and relax at the OTN Lounge, learn a lot of different things, spot Oracle Hero’s as the wander by if you are a “regular” visitor to OOW. And, by all means, I recommend you do as it is extremely valuable.
But the difference this time was that I really belonged there.
A very big thank you to Jennifer for the hard work you put into making all of this possible!
And, please, support Girls who Code, the initiative OTN sponsorred this year by tweeting a selfie with the hashtag #girlswhocode and the appropriate sticker!!

#doag2016 my picks and suggestions

As many conferences evolve over the years, the number of sessions on offer can easily be overwhelming. I have overheard many conference attendees wrestling with their choices for what to see and which sessions to attend.

For DOAG 2016 I have a short overview with my picks and with one or two tip-sessions. I hope this helps, though it is just my personal preference of course…

Please note that this post is based on the printed version of the conference planner and this may obviously be subject to change. Find the on-line version of the conference planner here!

And!!
Do not forget…
The first ever APEX Hack’a’thlon is going down on Friday the 18th of November at the DOAG Education day. If you are interested or just want more information, don’t hesitate to drop a line.

#DBADev (Ops), who knows what is going on…

I have been considering writing this article for quite some time now.
APEX Connect 2016 in Germany’s capital Berlin and the DOAG Database days have finally persuaded me to talk more about #DBADev, let me explain why…

Whenever in the stone age…

During my career as DBA, I was always working closely together with Oracle Forms & Reports developers. In retrospect, the cooperation in that time was remarkable.
These Forms & Reports developers had always been used to working on a host-based platform.

For those of you who actually remember Oracle Forms & Reports and wonder…
Was there ever Forms & Reports host based?
Yes there was, but it is creepily long ago!!

Because of the nature of Forms & Reports, there always was a lot of consideration about where to place application code. This especially became true when PL/SQL was introduced and the migration to Oracle Forms & Reports 6.5 came about.
This brought the transition to client/server based computing and introduced physical distance between the database and the “front-end”.
Front-end between quotation marks, as in today’s world we don’t actually know “front-end” anymore in this same qualification. The “Frond-end” was always more elegantly and fittingly described as a “fat-client”, because of the sheer size of the software and utilities that were required on the end-users workstation.

The physical separation and distance between the presentation entity and the data manipulation engine required and inspired a lot of thought and debate on where the bulk of data processing had to be done.
You can imagine the impact of having a specific data manipulation done inside an Oracle Form that lived on a desktop on the other end of the network. Especially when the required data set is large. Having 1,000 records being fetched, where 2 where manipulated and then send back in bulk, repeated 100 times, 4 times a minute on a 10 Mbps network. OK, clear, that needs to be done smarter.
The solution: work with small data sets and do database side manipulation to limit client/server communication. And actually, that worked quite well!!

All good and fine… But how does this tie in to #DBADev? This already sounds so harmonious. And how could APEX Connect 2016 have inspired this article?

Well… Let’s see

Later on, I found that this cooperation appeared to be not so normal.
If you step out of the world of client-server computing and move on to “todays world”, that started more or less in the nineties with web based computing – or cloud-computing “avant la lettre“ or “my stuff on your computer” or however you describe it – you find a world that consists of “strange things”.
I find these things “strange things” because I believe they are suboptimal, and luckily I find myself not alone in this corner.
Suboptimal in a way that data manipulation solutions (lets call them applications for now) should be considered to be database agnostic. This independence dictates that you use the database as just a data store or even more accurately, as a persistency store. Blane Carter 2 minute TechTip

In another scenario these applications are designed and build by developers who are very good at creating intuitive and sharp looking user interfaces. Unfortunately often with a lesser developed understanding of the mechanics involved in dishing up and serving data to this newly established middle tier.

With the continuing professionalization of IT over the past 20 years, we have seen the creation of a wide variety of disciplines. These range from those who think about IT (architects, managers, designers) to those who build IT (programmers, engineers) to those who run IT (system administrators, operators) and the majority of these disciplines today are self-contained groups of professionals and specialists who excel at their own game. Basically that is good as the profession is wide and complex enough to support this.
The problem is that there is no longer anyone who has the whole picture.

Bring it on / together!

apex-logoAPEX Connect 2016, to me personally, was the first time I really saw #DBADev in practice. With the following two examples I want to illustrate my inspiration.

The first talk of this genre was @alexnuijten with his confessions, and subsequent smart tips and best practices in “Structuring an APEX application”.
As a pure database developer like Alex, you are automatically more prone to thinking about “DBA-stuff”. A lot of these best practices, although they are very database centric, like using a view for each application screen, are obviously primarily there to help the developer. And, don’t get me wrong, that is a very good thing! Alex inspires to try and combine the best of both worlds, which helps getting the most out of your application, your database, and therewith frankly, out of your total investment.

The second example was the information-packed presentation by Dietmar Aust @daust_de, called “Oracle APEX Scripting – die Kommandozeile ist Dein Freund“ (the command line is your friend).
Much more than “just about developing”, this presentation bridged gaps in more than one way. Perhaps it is even #DBADevOps if you think about it.

The recent DOAG Database days held a few additional surprises with the presence of @cczarski and @nielsdb. A very will pitched presentation by Bruno Cirone really sparked the growing interest in the topic!!

It is funny how an idea that was initiated some 18 months ago, conceived together with Sabine Heimsath @flederbine has grown and evolved out of natural demand. For me, this is one other aspect of the industry, where APEX is setting new frontiers.
With a growing awareness and more people recognizing the gap, the deficits it is bringing and the benefits cooperation brings, I have good hopes.

APEX is not only the technology that enables you to create web-based apps super quickly, it is also the technology that brings developers and DBA’s truly closer to each other, ensuring a maximum bang for the buck when it comes to utilizing your database infrastructure investments!
I am not saying we are there, but this is definitely a first step in the right direction!

DOAG 2014, Nüremberg visited

Traveling to Nuremberg, anticipating three days of Oracle submersion. There are so many speaker heading over there it cannot be anything but successful.
This will be the first conference I will attend after being accredited as Oracle ACE Associate which, for me, makes it again a little more special.TurboProp
The first surprise, though, was just that. Arriving, by bus, at the boarding-location, there was a Bombardier DASH8-Q400 waiting, which turned out to be a turbo-prop aircraft. Okay, I jumped from a Cessna Caravan twin engine turbo-prop before, but this was still a first. As I am writing these lines, we’re descending upon Nüremberg.

On the first day of the conference, which started with a beautiful but rainy morning stroll to the conference center, The action started to really kick in from about 12:00 with the first session of my good friend Peter Raganitsch, talking about the 10 worst practices in APEX. A refresingh way of looking at software development by focussing on how to do it wrong!
The day ended with one of the “most pleasantly unorganized sessions” of the conference, where Johannes Ahrends and Philppe Fierens joined me on stage for the Standard Edition Round Table, #DOAG14-edition.

The second day was full of sessions, and I vistited Joel Kallman “APEX fast=true”, discussing the the knowledge needed to do serious application development on APEX, creating #DBADev. And, off course, the sharp presentation of my friend Franck Pachot about interpreting AWR-reports!
At 17:00 it was time for my third event, the “Electronic Patients Records system based on Oracle APEX” talk, which had quite a good turnout.
GatheringThe day ended with a super-cool meet-up with Mia Urman, Lonneke Dikmans AND Brynn Llewellyn… And later on we had a real nice depiction of #DBADev 2.0, involving Joel Kallman, Philippe Fierens, Illoon Ellen and myself.

The third and last day of the conference was spend executing #RepAttack. This session concluded 3 full days of hands-on hacking with cool software and getting a feel of some of the new stuff.

A few of the cool new meetings (which we’ve dubbed the e-people to real people conversion by IRL) involved:

Thank you, DOAG, for a superb conference. I thoroughly enjoyed it. To all the Oracle aficionados, until next time!!
