Overview of this book

Scalability, performance, and reliability have to be designed into an application from the very beginning, as there may be substantial cost or implementation consequences if they need to be added down the line. This indispensible book will teach you how to achieve these things using Oracle Coherence, a leading data grid product on the market.Authored by leading Oracle Coherence authorities, this essential book will teach you how to use Oracle Coherence to build high-performance applications that scale to hundreds of machines and have no single points of failure. You will learn when and how to use Coherence features such as distributed caching, parallel processing, and real-time events within your application, and understand how Coherence fits into the overall application architecture. Oracle Coherence provides a solid architectural foundation for scalable, high-performance and highly available enterprise applications, through features such as distributed caching, parallel processing, distributed queries and aggregations, real-time events, and the elimination of single points of failure.However, in order to take full advantage of these features, you need to design your application for Coherence from the beginning. Based on the authors' extensive knowledge of Oracle Coherence, and how to use it in the real world, this book will provide you with all the information you need in order to leverage various Coherence features properly. It contains a collection of best practice-based solutions and mini-frameworks that will allow you to be more productive from the very beginning.The early chapters cover basics like installation guidelines and caching topologies, before moving on to the domain model implementation guidelines, distributed queries and aggregations, parallel processing, and real-time events. Towards the end, you learn how to integrate Coherence with different persistence technologies, how to access Coherence from platforms other than Java, and how to test and debug classes and applications that depend on Coherence.

Starting up the Coherence cluster


In order to get the Coherence cluster up and running, you need to start one or more Coherence nodes. The Coherence nodes can run on a single physical machine, or on many physical machines that are on the same network. The latter will definitely be the case for a production deployment, but for development purposes you will likely want to limit the cluster to a single desktop or laptop.

The easiest way to start a Coherence node is to run cache-server.cmd batch file on Windows or cache-server.sh shell script on Unix. The end result in either case should be similar to the following screenshot:

There is quite a bit of information on this screen, and over time you will become familiar with each section. For now, notice two things:

  • At the very top of the screen, you can see the information about the Coherence version that you are using, as well as the specific edition and the mode that the node is running in. Notice that by default you are using the most powerful...
