Definition

UWL caches items from different provider systems. This caching is done periodically as specified in the configuration XML for a particular item type.

You must clear the cache under the following cases:

  • ItemTypes are customized.

  • Systems are removed from portal landscape or a system configuration is removed from the UWL systems configuration page.

Cache Admin IView

To clear the cache, use the Cache Admin IView. Cache can be cleared for all systems or a particular system.

  • Select the dropdown list for System Alias, only those registered systems which have items in UWL cache appear in the list. If a system does not have any items in UWL cache it does not appear in the list.

  • Choose Clear Cache.

  • Choose Clear Expired Items to remove all expired items from the cache.
Note After specified time duration, the items retrieved expire in the cache. For more information, see the expiryTime attribute in theCaching topic.
