Cache tuning for federated documents
The federated documents feature uses the document list cache and the document data cache to manage information about the list of documents and the document data.
- The document list cache contains the list of document identifiers contained in the rule selection result of a specific user and a specific selection rule.
- The document data cache contains the metadata of a specific document.
Both caches are activated by default with a default cache entry lifetime of 10 minutes.
To tune these caches you can configure the Cache Manager Service (WP CacheManagerService) in the IBM WAS administrative console. Properties for the document list cache are identified by cacheinstance.com.ibm.pzn.wcm.ecm.DocumentListCache, and properties for the document data cache are identified by cacheinstance.com.ibm.pzn.wcm.ecm.DocumentMetaDataCache.
Updates occurring on the remote content management system might not immediately be reflected on the portal side if there is a corresponding entry found in the cache. The individual cache life time values determine the maximum time lag for corresponding updates.
- The time lag for new documents becoming visible and deleted documents being removed depends on the lifetime value for the configured document list cache.
- The time lag for updates in the metadata describing a document (for example, changes to the document title) depends on the configured lifetime value for the document list cache.
The user-specific document list cache is explicitly invalidated each time the user logs in, so that the most current list of available document identifiers is available upon login.
