Oracle Coherence is a JCache-compliant in memory distributed data grid solution for clustered applications and application servers. Oracle 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 cluster-wide 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 Oracle 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.
