Use external caching to improve performance by storing SQL repository data in the memory of a separate distributed cache application. This section explains how to configure the Oracle ATG Web Commerce platform to connect to a distributed cache application. See information about configuring the way your application uses external caching in the Repository Guide.

The Oracle ATG Web Commerce platform includes an adapter for the Oracle Coherence data grid application. Install and configure Oracle Coherence before using the external caching feature. See information about Oracle Coherence at http://www.oracle.com/technetwork/middleware/coherence/documentation/index.html.
