COMPOSITE APPLICATIONS TUNING

For the Composite Application Infrastructure scenario, we started with the tuning given in the Base Portal Scenario above. However, the Composite Application Infrastructure scenario accesses a large number of applications, and therefore a large number of pages and portlets. Therefore there is higher demand on some of the caches in WebSphere Portal; to improve performance in this scenario, we modified the sizes of some of the caches in WebSphere Portal.

Cache Manager Service Properties

The following values were specified in CacheManagerService.properties in addition to the parameters changed in the Base Portal tuning. We recommend that you monitor the caches in your environment to determine which caches might need tuning.
