Stop the data flow from source server (published data source)

If you used AVEVA Insight Publisher to publish a data source to AVEVA Insight, you must first stop the flow of data from the source server before you can remove the AVEVA Insight data source.

Note: When you remove an entire data source, all of its related tags are also removed from AVEVA Insight.

To stop the data flow from the server

1. Stop the flow of existing tags and data from the AVEVA Insight Publisher to AVEVA Insight:

   1. Open Windows Task Manager and select the Services tab.

   2. From the list, right-click "aahSupervisor (Wonderware AVEVA Insight Supervisor)" and select Stop Service.

2. Stop and clear out any store-and-forward history blocks:

   3. Open Windows Task Manager and select the Processes tab.

   4. From the list, right-click "aahIDAS.exe" and select End Process.

   5. Open Windows Explorer, navigate to the store-and-forward path (C:\ProgramData\Historian\StoreForward, by default).

   6. Delete the store-and-forward history block folders that start with "A000000_00N" where N represents an integer; for example, 'A000000_001".

Now you can safely remove the data source from AVEVA Insight.

In the event that the data source was removed from AVEVA Insight before stopping the data flow from the server, the AVEVA Insight Publisher will continue to attempt publishing data to AVEVA Insight and log error messages to the ArchestrA System Management Console. To correct this, perform the following steps:

3. On the server, navigate to C:\ProgramData\Archestra\Historian\Hosting\Configuration and open StartupConfig.json in a JSON editor.

4. Locate the Application node and identify the grouping containing the data source.

   Referencing the PublishedFrom parameter can help with identification

5. Delete the entry as shown in the example below:

   Before [ "Applications": [ { "Path": "", "Arguments": "", "PipeHome": "", "RestartCriteria":{ "MaxCpuPercent": 0, "MaxMemoryPercent": 0, "MaxHandleCount": 0, }, "InstanceId": 0, "ApplicationType": "", "PublishedFrom": "" } ] ]

   After [ "Applications": [ ] ]

6. Save the file.
