Oracle Coherence 3.5

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.

Implementing the client application


In the remainder of this chapter we will do a quick run-down through Coherence for .NET API and cover pretty much the same topics and in the same order as we did in Chapters 2 through 7.

Even if you are not particularly interested in .NET, this should provide a quick refresher of the topics we have covered so far, so you should probably not skip this section. You will also see that C# is very much like Java and that the Coherence for .NET API is very similar to the Coherence Java API, so following the examples should be fairly straightforward.

So let's start from the beginning…

Basic Cache Operations

In order to obtain a reference to a named cache, you need to use the Tangosol.Net.CacheFactory class and invoke the GetCache method on it:

INamedCache cache = CacheFactory.GetCache("countries");

Once you have a cache instance, you will probably want to put some objects into it and try to read them back. Similar to how NamedCache interface extends java.util.Map...
