|Oracle® Coherence User's Guide for Oracle Coherence
Part Number E12192-01
Oracle Coherence is a JCache-compliant in-memory caching and data management solution for clustered J2EE applications and application servers. Coherence makes sharing and managing data in a cluster as simple as on a single server. It accomplishes this by coordinating updates to the data using clusterwide concurrency control, replicating and distributing data modifications across the cluster using the highest performing clustered protocol available, and delivering notifications of data modifications to any servers that request them. Developers can easily take advantage of Coherence features using the standard Java collections API to access and modify data, and use the standard JavaBean event model to receive data change notifications. Functionality such as HTTP Session Management is available out-of-the-box for applications deployed to WebLogic, WebSphere, Tomcat, Jetty and other Servlet 2.2, 2.3 and 2.3 compliant application servers.
This document is targeted at software developers and architects. It provides detailed technical information for writing and deploying C++ and .NET applications that interact with the Coherence cache. It also provides information on integrating Coherence with the Web Logic Server (WLS), TopLink Essentials, and Hibernate.
Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
