System Tasks are specialized tasks that perform generic maintenance and cleanup functions on the OnBase database. System Tasks belong to the <System> Task Group and are automatically created by the system the first time that the Unity Management Console is opened, or the first time that an instance of the Unity Scheduler Service is run.
A dedicated instance of the Unity Scheduler Service can be installed to execute System Tasks, or any running Unity Scheduler Service instance automatically executes them.
Upon creation, System Tasks each have a default schedule that can be modified as needed.
The following table describes the System Tasks that are created.
