Reminder: Free, Global, Virtual Developer Day November 5th

Just a quick reminder about the FREE virtual developer day focused on Coherence (and WebLogic) coming on November 5th.

This day, with content tailored for developers, will guide you through tooling updates and best practices around creating applications with WebLogic and Coherence as target platforms. We'll also explore advances in how you can manage your build, deploy and ongoing management processes to streamline your application's life cycle. And of course, we'll conclude with some hands-on labs that ensure this isn't all a bunch of made-up stuff - get your hands dirty in the code!

November 5, 2013
9am PT/12pm ET
REGISTER NOW


We're offering two tracks for your attendance, though of course you're free to attend any session you wish. The first will be for pure developers with sessions around developing for WebLogic with HTML5, processing live events with Coherence, and looking at development tooling. The second is for developers who are involved in the building and management processes as part of the application life cycle. These sessions focus on using Maven for builds, using Chef and Puppet for configuration and more.

We look forward to seeing you there - don't forget to invite a friend!

Coherence on Exalogic: 6x Speeds on Half the Hardware is Possible

Recently, Oracle Coherence released its 12c version, focused on scalability and real-time data delivery. As part of the launch, we showcased Coherence's tight coupling with Exalogic Elastic Cloud. By leveraging the Inifiniband Fabric in Exalogic, Coherence can now operate at up to 6x the speed on as little as half the hardware on an Exalogic box. This breakthrough is helping customers save money on their hardware costs while improving performance of their data grid.

Here's a free resource available for you to explore this technology relationship further.



For even more information on Coherence, attend our upcoming free virtual developer day on November 5th to see how developers can leverage Coherence in their everyday tasks.

Spotlight on an ACE: René van Wijk

Oracle ACEs and Oracle ACE Directors are known for their strong credentials as Oracle community enthusiasts and advocates, with candidates nominated by anyone in the Oracle Technology and Applications communities. They provide not only external expertise on Oracle products, but also real-world examples and implementations of the Oracle stack, including many experts on Coherence and WebLogic.

One such expert is René van Wijk, who calls the Netherlands home, and is an active member of the ACE community, and works regularly with Coherence.
René is a graduate of the Delft University of Technology. Since then he has been with working with much of the Oracle stack (including WebLogic and Coherence), and is also an expert in many open standard frameworks. René transfers his knowledge and experience regularly through training, publications and presentations at Oracle-related seminars and conferences.

René, most importantly, likes to relax; travel (for leisure and take photos), watch movies, listen to some fine music, and enjoy nature hikes.

Looking for some Coherence insight from René? You'll find a ton of resources on his site, Middleware Magic. 

Follow René on Twitter: @Middlewaremagic

This post outlines how to do this and comes with a simple Java example you can try out yourself. [Read More]
