Learn
  • Best use distributed caching to reduce the load on the backend database
  • Design and implement your domain objects to work most effectively with Coherence
  • Apply Domain Driven Design (DDD) principles to Coherence applications
  • Query and aggregate data efficiently within the Coherence grid
  • Boost application performance by executing tasks in parallel within the grid
  • Leverage Coherence events and continuous queries to provide real-time updates to client applications
  • Integrate various persistence technologies, such as JDBC, Hibernate, or TopLink, with Coherence
  • Access Coherence from .NET and C++ applications using Coherence*Extend
  • Test and debug Coherence-related code

Chapter 1, Achieving Performance, Scalability, and Availability Objectives discusses obstacles to scalability, performance, and availability and also some common approaches that are used to overcome these obstacles. It also talks about how these solutions can be improved using Coherence.

Chapter 2, Getting Started teaches you how set up Coherence correctly in a development environment, and the basics of how to access Coherence caches, both by using the supplied command-line client and programmatically.

Chapter 3, Planning Your Caches covers various cache topologies supported by Coherence and provides guidance on when to use each one and how to configure them.

Chapter 4, Implementing Domain Objects introduces the sample application we will be building throughout the book and shows you how to design your domain objects to take full advantage of Coherence.

Chapter 5, Querying the Data Grid teaches you how to use Coherence queries and aggregators to retrieve data from the cache in parallel.

Chapter 6, Parallel and In-Place Processing covers Coherence features that allow you to perform in-place or parallel processing within a data grid.

Chapter 7, Processing Data Grid Events shows you how to use powerful event mechanisms provided by Coherence.

Chapter 8, Implementing Persistence Layer discusses options for integration with various data repositories, including relational databases.

Chapter 9, Bridging Platform and Network Boundaries covers the Coherence*Extend protocol, which allows you to access a Coherence cluster from remote clients and from platforms and languages other than Java, such as .NET and C++.

Chapters 10, Accessing Coherence from .NET and Chapter 11, Accessing Coherence from C++ teach you how to access Coherence from .NET and C++ clients, respectively.

Chapter 12, The Right Tool for the Job, provides some parting thoughts and reiterates practices you should apply when building scalable applications.

Appendix, Coherent Bank Sample Application, describes how to set up the sample application that accompanies the book in your environment.

About

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.

Features
  • Build scalable web sites and Enterprise applications using a market-leading data grid product
  • Design and implement your domain objects to work most effectively with Coherence and apply Domain Driven Designs (DDD) to Coherence applications
  • Leverage Coherence events and continuous queries to provide real-time updates to client applications
  • Successfully integrate various persistence technologies, such as JDBC, Hibernate, or TopLink, with Coherence
  • Filled with numerous examples that provide best practice guidance, and a number of classes you can readily reuse within your own applications
