14.8 Dynamic Cache Monitor
J2EE applications have high read/write ratios and can tolerate small degrees of latency in the currency of their data. WAS consolidates several caching activities, including servlets, Web services, and WebSphere commands into one service called the dynamic cache. These caching activities work together to improve application performance, and share many configuration parameters, which are set in an appserver's dynamic cache service.
Therefore, the dynamic cache opens a field for significant gains in server response time, throughput, and scalability. Use the dynamic cache to improve the performance of servlet and JSP files by serving requests from an in-memory cache. Cache entries contain servlet output, results of servlet execution, and metadata.
The Dynamic Cache Monitor is an installable Web application that displays simple cache statistics, cache entries and cache policy information. For detailed information, see Chapter 10, Dynamic caching.
