OTN Tour Latin America 2016: Chile

Oracle Technology Network Tour Latam 2016:
Santiago de Chile

The conference in Chile was exceptional for a couple of reasons. For the first time ever I met German, the tech reviewer of my WebLogic 12c book. A great guy (not sure if he wants to read his name here – just get the book, he is in the acknowledgement!) who did a brilliant job in editing the 12c book. We had lunch together with his friends from Oracle ACS and the best I can say it felt like friends you know for years and not somebody you met 30 minutes ago. It was a pleasure meeting you guys!

The conference itself was the University San Sebastian in Bellavista area. Quite a few presentations were running in several rooms in parallel.

Also Santiago is great. From every traffic jam you can see the mountains! It is really a pity I couldn’t go to any more remote places like Atacama desert or Torre de Paine. Anyway both are now top on my to-travel list. My friends know what this means. Stay tuned.

Again I did a Docker live demo. The audience seemed to like it, what do you think? Also the room was big enough for big ideas. Big thank you to CLOUG and Felipe Manriquez.

The non Conference Part

I did not really have a lot of time for sightseeing but I managed to nip out and have a seafood lunch at the Mercado Central before heading to airport. Actually a memorable drive, since the Uber driver was driving alongside the runway but was not able to find the airport 🙂

OTN Tour Latin America 2016: Argentina

Oracle Technology Network Tour 2016 Buenos Aires

Buenos Aires was the first city of the OTN tour where I was slightly less busy. We got there by ferry from Montevideo. Arriving at the conference site we could already see our pictures in the elevators:-) I talked about WebLogic Server 12c, the heart of SOA and did a live demo about Oracle’s perspective on Docker.


The Conference

Apart from delivering my own presentations, also I attended Carlos’s Sierras workshop about tuning tools for data bases. Conference itself was great, very well organized and again I met some great people who became friends.

Also I was asked to give an interview about the importance of conference like the OTN tour for students.

Some Sightseeing

I did a half day city tour with Carlos during half a day off.

By the way here is a link to a video compiled of even more photos about Argentina.

OTN Tour Latin America 2016: Brazil

Oracle Technology Network Tour Latam Sao Paulo

I attended the 2016 OTN Tour Latam. First stop was Brazil which was on my personal to-travel list for a long time. Still I hesitated for many years to finally go to Brazil because it was clear to me that I wouldn’t be able to communicate a lot. Earlier this year managed to learn about 16 words in ภาษาไทย – which by the way got me one of the best laughs of the last 5 years in one of the city’s swankiest rooftop bars. So guys, learn languages!

My Personal Challenge

Anyway, I sometimes like challenges and my plan for Brazil was to be able to speak some 100 words of Portuguese. After a bit of research, I quickly found a teacher in Munich (Bom dia, Chris!), studied and finally managed to achieve at least 50% of my goal (blame the usual boring excuses for missing the other 50%, but I was still better off than 95% of all other travellers).

GOUB Tech Day: OTN Tour

The conference including the auditories were very good. I met many old friends, made too many new friends to list them all here, listened to great presentations from colleagues, and we had a wonderful, meaty conference dinner with a good selection of drinks. Actually I enjoyed everything, maybe except the surprisingly unfriendly and unprofessional reception at Blue Tree Morumbi Hotel.


I did a presentation about Oracle WebLogic (12.2.1) 12c and one about Docker.

Have a look at the pictures gallery here to get some more impressions! Slides will be uploaded in a few days.



Zero Downtime, REST, Domain Partitions / Multi Tenancy, Elasticity and WLDF. WebLogic 12.2.1 (12c)

I just finished a two week long hands-on consulting session for some pretty experienced application managers and architects at one of Europe’s premier financial services institution.

In 5 days we explored WebLogic 12.2.1 extensively:

  • Zero Downtime
  • REST
  • Domain Partitions / Multi Tenancy
  • Resource Group Management
  • Java Mission Control
  • WLST
  • Elasticity
  • JMS Clustering
  • WLDF



Here is some feedback from the group. You can tell we had fun, although we worked very hard.

This is how a happy group looks like.



People seemed to be happy, here is what they liked.

Zero Downtime: Restart Admin Server from Admin Console / Rolling Restart of Servers or Cluster (WebLogic 12.2.1)

Before WebLogic 12.2.1 I was often asked if there is any OOTB restart of the admin server, especially from the admin console. Now with WLS 12.2.1 it can be done easily. Also of course you rolling restart a set of servers, a cluster or two, or whole domain!

  • Admin Server has to be assigned to a machine
  • Admin Server has to be started under nodemanager

Goto DOMAIN / ZDT Control / Domain | Cluster | Servers, chose what you would like to rolling restart, then click on Patch.

Select Rolling Restart.
