Integration Server provides user tasks that you can modify. For example, Integration Server supplies the Message History Sweeper task if you configured a document history database for exactly-once processing. This task removes expired entries from the document history database. Even though Integration Server scheduled this task, you can modify how often the service runs.

In addition to the scheduled user tasks that you set up, Integration Server schedules system tasks that it performs for normal system operation. You can view, but not update or cancel, most scheduled system tasks.
