iamspeaking oow15I will be presenting an expert session together with Dave Cabelus from Oracle WebLogic product management about the newest WebLogic 12c at Oracle Open World 2015.

Do you know about WebLogic 12 resource management policies for heap that can trigger a slow action? WebLogic’s microcontainer for multi tenancy? Scale up actions for elastic clusters? createForms for the RESTful management APIs? why Docker is almost zero overhead, how Docker works with WebLogic and that it is officially certified by Oracle?

Come and see us, Tuesday 18h.

OTN Tour Latin America 2015: Colombia

col goldColombia was my last stop on the OTN tour, yet it was the country I was waiting for. I had good memories about the country from many years ago when I was backpacking there and it was a pleasure to see how everything has changed.

I decided to take a hotel in the north which is closer to the some shopping malls and various museums. At night after arrival I got a local SIM card which was a breeze and cost less than 10€ for 1 GB of data. First day I nipped out, crossed the main street to the Alcaldía and headed straight to the Museo del Oro Calima (Gold Museum).

The conference was organized by charming Giovanna Bohorquez Paez and her team from the Asociación de Usuarios Oracle de Colombia. Everything went swimmingly and I felt flattered to give a Docker and WebLogic presentation at the Universidad Autónoma de Occidente. Due to some changes there was no time left for my 12 Things about WebLogic 12c presentation but feel free to download the presentation slides. For the first time I had the pleasure to meet Mauricio Naranjo in person. During the coffee break we had a exotic looking but surprisingly well tasting drink called Champús (check this wiki link for a pic!).

Altogether I enjoyed the conference a lot. It was a great atmosphere, people came to ask questions and to have their pictures taken together with us. To respect their privacy I put a picture of us below.

At the end, I decided to stay an extra day, visited some lookouts and local bars with a friend who also gave me a lift to the mountain range called KM18. Calenos love to go there because it is much cooler, so it is really crowded on Sundays. There I had an even stranger but also even tastier (!!) drink called agua de panela (sweet hot drink made of sugar cane) with savory cheese in it. Loved it!



OTN Tour Latin America 2015: Panama

Panama City


Panama was another interesting place to be. Very few Europeans I know have ever been to Panama. The trip from the airport started with a glimpse of Panama’s surprising skyline. Pleasant enough I was located in the 29th floor (!) of a downtown hotel.

20150821_095650The conference was a bit further away towards the canal at another hotel next to one of the biggest shopping malls in the known universe.

I had the last slot and since we were running late, people volunteered to stay a bit longer for my Oracle WebLogic and Docker presentation.

Saturday we had a day off. Edgardo Sanchez from the local user group took us on a trip to the Panama canal and Casco Antiguo (the historic center of town). I am not a good shopper, usually I am buying nothing at all, but at the end I bought a Panama coffee mug as a souvenir.

Btw, I uploaded the WebLogic with Docker and 12 new features of Oracle WebLogic Server 12c presentation slides.


OTN Tour Latin America 2015: El Salvador

San Salvador

In San Salvador I had the best hotel experience. I got upgraded for no particular reason to the executive lounge which provides a view to the local volcano (and free soft drinks).

Also I met Alex Gorbatchev from Python for the first time in person. The conference was at a military club in a very relaxed and safe atmosphere. Anyway, I felt a bit like the scene in the Monty Python clip with the comfy chair since it was really hot and we faced a splendid swimming pool without having the time and/or possibility to go for a swim.

Again I did two presentations one about Docker in general and its usage for WebLogic with  and one about 12 new features of Oracle WebLogic Server 12c both with great audience feedback and participation. After the session there was a high number of people asking for the slides and trying to get some answers on additional topics. My impression was that a smallish but very interested group of people is working with WebLogic and that everybody was curious about Docker.

Same as in Guatemala the conference ended with a picture taking session :-) Heli from Finland has another blog posting about the fun part of our trip.

OTN Tour Latin America 2015: Guatemala

Guatemala City

I attended this year’s OTN Latin America 2015 tour and travelled across 5 countries.


Guatemala was one of the places I always wanted to visit so I arrived a day early on own expenses. My flight was via FRA and Houston and I arrived at GUA City an hour and half before midnight. My suitcase did not. It took an hour until somebody from UA showed up at the airport so I missed Deiby from the local user group who volunteered to pick me up at the airport on a Friday night.


The following day I did a trip to the historic city of Antigua, the old capital including a guided walk through the center and an easy walk up to Cerro de la Cruz which offers a breathtaking view to the surrounding volcanoes and Antigua.

The conference itself was an excellent experience (thanks to Deiby Gomez and his colleagues!), perfectly organized and coordinated with a great mixture and huge number of local and international speakers. For the first time I met Daniel Morgan, Anton Els (see his posting for the fantastic boring / exciting pic we took!), Edward Roske, Björn Rost and Jeff Davies in person. One of the cool things of an OTN tour is that you can listen also to a lot of great people so I attended most of Dan’s and Jeff’s session but unfortunately missed Anton’s sessions.

My own session was well attended. I guess that over 100 people showed up which was a big surprise to me! My Spanish is slightly above Tarzan level, still I decided to give the introduction in Spanish and the rest in English, which on the one hand side was confusing for the live interpreter and on the other hand side entertaining for the audience. At the end of the day we had a lovely speakers dinner playing a bit of golf while having excellent food.
