April 2010

Oracle TopLink 11g Release 1 (11.1.1) includes tight integration with Oracle Coherence. This integration, provided through the TopLink Grid feature, marries the standardization and simplicity of application development using the Java Persistence API (JPA) with the scalability and distributed processing power of Oracle Coherence Data Grid.

This document explains how to use:

• TopLink Grid to leverage the Coherence data grid as the primary data store for entities

• Coherence as a distributed shared cache

• Coherence's parallel processing support to perform JPQL queries on cached entities

• EclipseLink JPA's optimized CacheStore and CacheLoader implementations in traditional Coherence applications

This document includes the following information:

• Understanding the TopLink Grid Integration

• "Traditional Coherence" Configuration

• "JPA on the Grid" Configurations

• Queries

• Labs and Examples

• Documentation Accessibility
