Managing the Participant Cache
To improve the access time required for users, user-defined groups, and organizations, Windchill maintains an in-memory cache of user, user-defined group, and organization information.
* 
If user, user-defined group, or organization attributes are changed using an administration tool other than the Participant Administration utility (for example, using a directory administration tool), then the cache containing those attributes must be purged in order for Windchill to display the changed attributes.
You can manage the participant cache in two ways:
By setting the maximum time that the information about a participant can remain available in the cache. Cache entries are automatically purged when the system accesses stale entries.
By selecting actions that purge information from the cache from within the Participant Administration utility.
