Jaspersoft OLAP caches OLAP query results and metadata (such as cube structures and data source connection information) in memory. Cached items are removed automatically through JVM garbage collection, where the least-recently-used items are cleared first. However, when new data is loaded into a database accessed by Mondrian connections, the cache must be cleared; otherwise, OLAP query results cannot include the new data. The cache must also be flushed when you modify Mondrian client definitions or their data sources.
For information about creating XML/A sources and connections, see theJaspersoft OLAP User Guide Jaspersoft OLAP User Guide.
