This series focuses on the best practices for the integration of IBM® WebSphere® eXtreme Scale DynaCache in WebSphere Commerce Server environments. WebSphere eXtreme Scale is a distributed caching solution that is a popular provider of DynaCache in large WebSphere Commerce Server environments. WebSphere Commerce Server customers have successfully integrated WebSphere eXtreme Scale DynaCache in large and small production environments. While the configuration of WebSphere eXtreme Scale DynaCache in a WebSphere Commerce Server environment is simple, you need to pay special attention to the best practices for design, usage, operational patterns, and tuning.
This three-part best practices series focuses on the tips and techniques involved in integrating WebSphere eXtreme Scale DynaCache into WebSphere Commerce Server environments. The tips and techniques in this series are based on successful launch experiences with some of the largest WebSphere Commerce Server installations. The series includes information about designing, deploying, configuring, and tuning applications in WebSphere Commerce environments.
When designing any WebSphere eXtreme Scale grid, you have to determine the amount of heap space, number of WebSphere eXtreme Scale servers, amount of physical RAM, number of physical machines, and a few other parameters. The DynaCache and general WebSphere eXtreme Scale grid sizing technique is described in the "Dynamic cache capacity planning" topic on the WebSphere eXtreme Scale information center.
In any environment, it is important to monitor the health of the WebSphere eXtreme Scale grid and collect statistical information about grid usage. These are a few simple strategies that can be used to monitor the overall health of the grid and generate operational alerts when necessary.
