xSuite Bus Prism Administration Guide

Task Scheduler

The scheduler allows you to launch previously created actions on a specific date/time or at a desired interval.

You can configure a validity period, priority, the interval type, and error handling for the action.

The scheduler is used when the master data is made available. For instance, the table-mapping action is set to schedule the time when data is fetched and another task is stored for automatic compilation of the IRIS master data.

Notice

A task from the Task Scheduler section is only executed if it is also assigned as a task in the  Assigned Scheduler Tasks section of the Windows IIS Services. A task should always be assigned to a single service.

In the upper section of the scheduler, a list will be displayed that shows all tasks currently set up. The different columns will help you to quickly grasp the nature of the task to be completed.

  • Weekly – Once a week. Choose the day of the week in the selection list and specify a time in the time input field. The task will then be executed weekly on the day and at the specified time specified.

  • Hours (hourly), Minutes (each minute), Seconds (each second), Milliseconds (each millisecond) An input field is displayed for configuring the time interval in the respective unit. The task will be executed repeatedly depending on the interval set.
