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.

Opatch for Oracle WebLogic 12c or Oracle Fusion Middlware

Those of you who blog will know that the most useful postings are the ones that you lookup yourself now and then. This one I was pulling out of my virtual class room drawer several times when asked by customers.

opatch webcast

Quite a while ago I did a webcast about the new patching utility opatch (read the original Oracle opatch documentation for 12.2.1 here). Opatch is now used with Oracle WebLogic Server 12c but also with Oracle Fusion Middleware products such as service bus and SOA suite.

P.S. opatch is of course covered in my latest Oracle WebLogic Server 12c book.

 

Tiny Improvement, Big Difference: Revert Production / Development Mode in WebLogic 12.2.1 Admin Console

A lot of people felt it was never right that you could not go back from production mode to development mode in WebLogic admin console. You alway could change it using WLST or overwriting it with a startup parameter or modifying config.xml.

With WebLogic 12.2.1 this has changed. You can change it using the admin console now.

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!
