Use external caching to improve performance by storing SQL repository data in the memory of a separate distributed cache application. Caching SQL repository data speeds your application by avoiding database transactions when that data is required by users. External distributed cache applications coordinate cache management for a cluster of application servers, offloading data from the Java virtual machine and increasing the amount of memory available to the application.

This section explains how to configure the way your Oracle ATG Web Commerce application uses external caching. See information about configuring the Oracle ATG Web Commerce platform to connect to a distributed cache in the ATG Installation and Configuration Guide.

The Oracle ATG Web Commerce platform includes an adapter for the Oracle Coherence distributed cache application. You will need to understand how to configure that product in order to use the external caching feature. See information about Oracle Coherence at
