About Background Queues
During day-to-day operation of Windchill, certain system tasks must be completed immediately, while others can wait until a more convenient time. For example, updating indexes based on events included in the indexing policy must be completed, but you may decide to defer that processing, consigning those tasks to a queue where they can be run at specified intervals. For example, usually many Windchill tasks, including updates to Windchill Index Search, email notifications, and many life cycle tasks, can be moved to an ordered background queue rather than being executed immediately.
To keep your system running efficiently, perform regular queue maintenance. For more information, see Exécution d'une maintenance régulière des files d'attente.
You can configure background queues with Windchill property values defined in the wt.properties file. The Queue Management utility provides you with capabilities for creating and managing background queues. This utility can be accessed from the Site > Utilities page.
