Introduction

In order for the master controller (and Forecasting Shell Server) to run properly several maintenance workflows must be scheduled. These workflows make sure the database does not overflow (they run the rolling barrel) and that configuration marked to be removed using the Configuration Manager actually gets deleted. In addition, each FSS must also run a rolling barrel task, usually once a day. This task runs the rolling barrel on the FSS and deletes configuration marked for deletion.

  • MC:MarkedRecordManager - Removes records marked for deletion. This removes static entries only.
  • MC:Synchronisation - Syncronise between several master controllers, only needed on duty standby systems
  • MC:RollingBarrel - Removes expired records from the MC database (e.g. timeseries, model states etc)
  • RollingBarrel_FSS00 (one for each FSS) - Removes expired records from the FSS database

Please ensure that the master controller workflows uses exactly the names as specified. For each workflow to be scheduled in the Administrator Interface a properties file should be made. Examples are attached to this page. For more information on the Administrator Interface (AI) consult the User Guide Admin Interface-Delft-Fews.pdf file (not yet on-line).

Scheduling the workflows using the Administrator Interface (AI)

First, each workflow must be uploaded. For each of the MC workflows this is the same dummy workflow. In the AI go to the Workflows and FSSs -> Workflow menu and choose upload new workflow to do this.

Please note that the Rolling Barrel for the FSS is a 'real' workflow (it can be run stand-alone) and should be uploaded using the Configuration Manager.


Next you should choose the file to be uploaded; the dummy workflow in the case of the MC workflows. Please ignore the warning about the Configuration management tool:

After uploading each workflow should be assigned to run on the Master Controller. This is done by using the Workflows and FSSs -> Workflow FSS Mappings menu. Each MC workflow should be assigned to the synchroniser as shown in the example below:

Now the workflows can be scheduled using the Forecast Tasks -> Schedules tasks -> Schedule new task menu item. When scheduling you should make sure you specify the appropriate properties file for each workflow type:
