After you click Cache on the system toolbar of the JReport Administration page, the entries to the following panels are available on the drop-down menu. The panels help you to configure the cache settings of JReport Server.
The JReport data cache system allows you to schedule and cache just the datasets used in your reports without actually running the reports. When the end user selects a report that is linked to a cached result set the data is retrieved from the cache and not from the DBMS. This is especially useful for month and quarter end reports where multiple reports use the same dataset with the same parameters such as begin and end date. See Managing cached report data for more information.
The report cache allows report templates and catalogs to be cached for faster access. The security cache allows you to configure how many users, groups and roles to cache without going back to the JReport Server database. The image cache allows you to configure how many images to cache.
