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.

Chapter 2. Getting Started

When I first started evaluating Coherence, one of my biggest concerns was how easy it would be to set up and use, especially in a development environment. The whole idea of having to set up a cluster scared me quite a bit, as any other solution I had encountered up to that point that had the word "cluster" in it was extremely difficult and time consuming to configure.

My fear was completely unfounded—getting the Coherence cluster up and running is as easy as starting Tomcat. You can start multiple Coherence nodes on a single physical machine, and they will seamlessly form a cluster. Actually, it is easier than starting Tomcat.

In this chapter, you will learn how to install Coherence on your machine and how to configure your development environment to make working with Coherence as easy as possible. We will then cover the basics of the Coherence API as we develop a small utility that will allow us to import data into Coherence from CSV files. Finally, we will talk...
