DOAG Conference 2015 – It’s a wrap!


20151117_175947DOAG Conference is completed and it was a good one. I did two presentation, both are available for download now from the official DOAG site and from slidshare:

Also I enjoyed meeting my top 3 customers at the conference, attending some great sessions about Hadoop Security, API management and Dueck’s keynote (elaborating about how to treat techies more like cats than dogs, instead of talking about volkswagening). Also, for the first time we had an Oracle ACE dinner organized by Björn Rost and Martin Klier – thanks to OTN!

JDK 8 and WebLogic 12.2.1

WebLogic 12.2.1 is available since Open World 2015.

Some news regarding Java and WebLogic 12.2.1:

  • javaWebLogic 12.2.1 requires Java 8 (JDK 8) as a runtime.
  • WebLogic 12.1.3 can be used with Java 7 or Java 8. Using WebLogic 12.1.3 with Java 7 caused warnings because of the permspace settings in the WebLogic start scripts. Permspace is removed from JDK 8, so also these warnings are gone now with WebLogic 12.2.1 and JDK8.
  • JDK 8 comes with Nashorn JavaScript engine. Try the jjs command line tool.
  • Main reason from a development perspective to upgrade: WebLogic 12.2.1 finally supports Java EE 7.
  • WebLogic 12.2.1 makes use of changes in the JVM. In JDK 8u40 a new feature was introduced to the JVM called resource management. Together with the G1 garbage collector WebLogic 12.2.1 uses this commercial feature to track resource usage (CPU, retained heap, # open file descriptors). It is enabled as follows:
    java   -XX:+UnlockCommercialFeatures  -XX:+ResourceManagement ...

Interview: The (Emerging) Role of the Cloud Architect

I did an interview in San Francisco hosted by Bob Rhubart with some well known folks of the industry including Sten Vesterli, Ronald Luttikhuizn, Simon Haslam, Arturo Viveros, and Ron Batra about the role of the cloud architect.

IMHO we won’t see many people with the job title Cloud Architect on their business card. It’s increasingly important and disruptive tech, every architect, team leader and CIO has to deal with it, however it’s tech that you as a professional have to understand. The cloud changes a lot if you do it right, read my article about cloud benefits.

Enjoy listening to the interview.bob


Oracle WebLogic / Coherence / Cloud SIG in MUC 2015 (German only)

WebLogic / Coherence / JCS SIG

I will be still travelling in Peru after delivering a presentation for the leading API management, microservices, and container conference SOALatam  in Lima, so I won’t be able to attend, but there is an interesting special interest group (SIG) meeting happening in Munich Germany if you want to know more about what was announced at Open World 2015. You can register here for the SIG.

DOAG 2015

Even before the SIG, if you are attending DOAG conference in Nürnberg this year don’t miss out my presentations about WebLogic 12.2.1 and WebLogic with Docker.


Next Stop: SOALatam Conference Lima / Peru


Just back from Oracle Open Word 2015 in San Francisco, it’s a great honor for me that my presentation Docker Containers: A Thorough and Critical Overview was accepted for the the SOALatam conference in Lima.

Most presentation will be in Spanish, I will the only non-latino speaker apart from Thomas Erl.

I am looking forward to a world class conference in Lima and to meeting friends such as Tabata Jessica Pérez as well as Rolando Carrasco and Arturo Viveros from the SOA myth buster team. Thomas Erl is the keynote speaker and it’s also a good opportunity to win a top notch computer science text book :-)

Heaps of reasons for a trip to Lima. CU there!
