By default the TFS warehouse is rebuild every hour. You can however change this default behaviour. You can either change the interval of the warehouse refreshment or you can refresh the cube manually. I knew how to do this on our TFS 2008 server, but the procedure has changed on the TFS 2010 environment.
Change the interval
To change the interval follow the following steps
1. Login on the Application Tier
2. Browse to http://servername:8080/tfs/TeamFoundation/Administration/v3.0/WarehouseControlService.asmx . You get a list of all available web services.
3. Click on the ChangeSetting webservice
4. You will see a new page where you can enter the setting and its new value. Enter in the SettingId: RunIntervalSeconds and in the newValue the number of seconds
5. Click on Invoke to change the setting
Manually refresh the cube
You can also choose to refresh the cube once. To do that execute the following steps.
1. Open the list of web services again with http://servername:8080/tfs/TeamFoundation/Administration/v3.0/WarehouseControlService.asmx
2. Select the ProcessWarehouse web service from the list
3. Enter in the collectionName the name of the Project Collection you want to refresh. The default collection is named DefaultCollection, but you can change that in the collection that is in use on your TFS environment.
4. Click on Invoke
5. Go back to the list of webservices and click on the ProcessAnalysisDatabase webservice, and enter in the processType textbox the value Full.
6. Click on Invoke
7. The data warehouse is now refreshed. This can take some time when you have a large database. To check the status of the warehouse update, you can check the GetProcessingStatus webservice. You can leave the parameters for the webservice blank to retrieve all information. The warehouse update is ready when all jobs have the “Idle” job status.
