Sample Coherence Cluster in Weblogic 12c by Nicolas Fonnegra


clip_image002Coherence plays an essential role inside the Oracle Cloud Application Foundation by providing an in-memory data grid for real-time data and event processing. Coherence delivers a series of features and benefits such as partitioned data caching,  support for Java/C++/.Net/Rest clients, distributed agents for remote data processing, real-time data query, event processing, transaction management and JPA support among others.

This blog will demonstrate how to create a sample Coherence cluster in Weblogic. A sample Java application will also be developed and it will be in charge of storing data into the Coherence cluster and consuming it. This sample cluster will be used as a starting point for future blog entries that will demonstrate other Coherence features.

The whole exercise follows these steps:

  • Configuration of the Coherence Cluster in Weblogic
  • GAR archive definition
  • Java client development
  • Deployment

Coherence Cluster Configuration

We will take a demo Weblogic domain with an admin server and two manage servers as a starting point. Read the complete article here.
