If a cache is not enabled, the property has a value of false, then no values are held by the cache and every cache lookup will return a null value. This property should only be modified for testing purposes, never in a production environment. The supported values are true and false and the global default value is true Supported values are true and false. The default values shipped in WebSphere Portal V6.1 should apply to most configurations. If you do not have a cluster there may be a small performance benefit to setting this property to false since a different cache implementation is used. We did not modify the defaults in our single node measurement environments Cache Usage Patterns Cache Instances com.ibm.wps.ac.PermissionCollectionCache Figure 1 Portal Access Control Cache Hierarchycom.ibm.wps.ac.AccessControlUserContextCache com.ibm.wps.ac.ProtectedResourceCachecom.ibm.wps.ac.OwnedResourcesCache com.ibm.wps.ac.RolesCachecom.ibm.wps.ac.ExternalOIDCache com.ibm.wps.ac.ChildResourcesCache com.ibm.wps.ac.ApplicationRoleOIDCachecom.ibm.wps.ac.ApplicationRoleDescriptorCache com.ibm.wps.ac.ApplicationRolesForPrincipalCache com.ibm.wps.ac.ContainedRolesCachecom.ibm.wps.ac.ApplicationRoleChildrenCache com.ibm.wps.puma.DNOIDCache / com.ibm.wps.puma.OIDDNCachecom.ibm.wps.datastore.services.Identification.OidAndUniqueName.cache com.ibm.wps.datastore.PortalIdCache.vpPerLpid.cachecom.ibm.wps.datastore.PortalIdCache.explicitLpidPerVP com.ibm.wps.datastore.pageinstance.OIDCachecom.ibm.wps.datastore.pageinstance.DerivationCache com.ibm.wps.datastore.pageinstance.DynamicNodeCacheM O D E L com.ibm.wps.model.content.impl.ResourceCache com.ibm.wps.model.factory.SimpleCacheKeycom.ibm.wsp.mode.content.impl.TopologyCache com.ibm.wps.model.factory.ContentModelCache.livecom.ibm.wps.model.factory.ContentModelCache.isolated com.ibm.wps.model.factory.NavigationSelectionModelCache.livecom.ibm.wps.model.factory.NavigationSelectionModelCache.isolated com.ibm.wps.model.factory.URLMappingCache.livecom.ibm.wps.model.content.impl.DynamicLoadCache com.ibm.wps.model.factory.URLMappingCache.isolatedcom.ibm.wps.model.factory.MultiModelCache.live com.ibm.wps.model.factory.MultiModelCache.isolatedcom.ibm.wps.services.vpmapping.VirtualPortalIDToRealmCache com.ibm.wps.model.impl.RuntimeClientMap.userAgent2clientwps.mappingurl.ContextsCache wps.mappingurl.LookupCachecom.ibm.wps.services.vpmapping.VirtualPortalIDToURLCache com.ibm.wps.services.vpmapping.URLToVirtualPortalIDCachewsrp.cache.portletdescription W S R Pwsrp.cache.servicedescription wsrp.cache.portlet.instancewsrp.cache.producer.user wsrp.cache.portlet.windowwsrp.producer.portletpool.pops wsrp.producer.portletpool.ccpsprocessintegration.PendingTasksCache wp.te.transformationAssociationCachecom.ibm.wps.policy.services.PolicyCacheManager com.ibm.wps.policy.services.UserPolicyNodeCacheManagercom.lotus.cs.services.directory.ldap.BasicLDAPDirectoryService.server P O L I C Ycom.lotus.cs.services.directory.ldap.BasicLDAPDirectoryService.user com.lotus.cs.services.directory.wmm.WMMDirectoryServicecom.lotus.cs.services.UserEnvironment com.lotus.cs.services.domino.DominoServicecom.ibm.wps.services.cache.cachedstate.CachedStateServiceCache.cache wp.xml.configitemscom.ibm.wps.pe.portletentity PortletMenuCacheRegistryService com.ibm.workplace.searchmenu.helper.SearchMenuCacheHelperDefault size 32, default lifetime infinite, usage pattern regular Default size 2500, default lifetime 3730, usage pattern regularExample Scenarios Now we shall consider some recommendations for specific scenarios We increased the lifetimes of all caches to at least one hour com.ibm.wps.datastore.pageinstance.OIDCache WEB CONTENT MANAGEMENT CACHES services/cache/iwk/strategy - WCM Item cachingservices/cache/iwk/objectsummary - WCM Summary WCM Cache Instancesservices/cache/iwk/module services/cache/iwk/processing - Advanced and Resour cesservices/cache/iwk/session - Session services/cache/iwk/menu - Menu services/cache/iwk/nav Navigatorservices/cache/iwk/abspath - Absolute path services/cache/iwk/missed - Missed Itemsservices/cache/iwk/libparent - Library Parent Services/cache/iwk/draftSummary - Draft SummaryUser cache user.cache.enabled=trueWebSphere Portal Information Center Mark Alkins, Manager Lee Backstrom, Document CoordinatorAndrew Citron Nathan Cook Sabine Forkel Uwe Haller Shibi John Klaus Nossek Kyung Lee Denny Pichardo, Technical LeadThe following are trademarks of other companies W E BS P HE R E P O R T AL V 6 . 1 T U N I N G G U I D E
