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 ...

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.

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.


Oracle Open World 2015

#OOW15 Wrap

Oracle Open World is finished and IMHO it was great! What I particularly enjoyed was that Oracle this year delivered a lot of what was announced last year. The cloud offerings seem to be heading the right way (Oracle uses industry accepted terms now when talking about cloud, concludes to my definitions and delivers across IaaS, PaaS and SaaS). In addition Oracle Fusion Middleware 12.2.1, in particular WebLogic 12.2.1 is out with multi tenancy micro containers, exportable partitions, a brand new REST management interface, new JDK support, new Java EE 7 support, policies, actions and true elasticity.

WebLogic Server 12.2.1 new features slides

The slides for my “12 Things You Should Know About Oracle WebLogic Server 12.2.1” presentation are available on slideshare:

Oracle Open World Expert Session: WebLogic 12cR2 (12.2.1)

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.
