WEBSPHERE PORTAL V6.1 TUNING GUIDE
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.
