ControlUnit

The ControlUnit is the heart of DOBBIN. It is invisible to the user. All JobClients post their jobs to the ControlUnit. The jobs are registered, collected and scheduled according to the job priority to the WorkUnits.

The ControlUnit must have access to the Database (local or external), the file server (can also be the local hard disk) and the WorkUnits. Also the JobManager(s) and JobDesigner(s) need to be able to access the ControlUnit.

The ControlUnit assigns a JobID when a request arrives from the JobClient - this is never done by the JobClient itself. The user is able to see the JobID as a string such as (Name) + Date + Time.

DOBBIN and the external JobClients are linked via WebServices. This way a flexible and platform independent means of communication is guaranteed.

The current status of the Job can be inspected using the JobManager.

The administration of the system can be undertaken either locally or per RemoteClient which communicates via the TCP/IP Port with the main system.
