Procedure

Viewing Tasks

●      In the Tasks screen area, you can view all tasks that have been created.

○       To activate or deactivate a task, select it and choose the Hold or Release pushbuttons, respectively.

○       To cancel a task, select it and choose Cancel.

A task scheduled by a ZeroAdmin-template cannot be cancelled, it can only be set to hold. A ZeroAdmin task is a task which belongs to a usage which comes with the installation of the system.

●      To sort jobs ascending or descending according to column content, select the heading of the column you want to sort.

●      To filter columns, use the standard filtering pushbutton.

Creating a Task

You create a scheduler task to set start conditions to a job definition. Instances of the job definition, or jobs, execute when the specified start conditions are fulfilled.
