Failed to open OMM stream - streaming services are unavailable

this is on behalf of a client, Powerseller:

Our existing side-by-side interface with Eikon allow us to start the Eikon environment, when it is not already open, with Eikon API .Net calls like these:

  • EikonDesktopDataAPI.EikonDesktopDataAPI.IEikonDesktopDataAPIEvents_OnStatusChangedEventHandler()
  • EikonDesktopDataAPI.EikonDesktopDataAPI.Initialize()

In the Workspace API documentation and tutorial examples, I cannot find any reference to an API call to start Workspace, if it is not already open. Right now, if Workspace is not open, I get the message from the errTxt variable.

{

"Error": "Failed to open OMM stream - streaming services are unavailable. Verify log details and ensure you have permissions."

}


We would prefer to be able to start Workspace automatically, like we do in Eikon, if it is not currently open. Without this functionality we would require the user to manually start Workspace before initiating our pricing request from the PowerSeller application.


Are there any API calls for Workspace to initialize/start the Workspace environment similar to what we used in Eikon?

Thank you for reaching out to us.

According to the code (EikonDesktopDataAPI), you are using the (Deprecated) COM APIs for use in customer applications. COM APIs are not available on Workspace so you can't use the APIs on Workspace.

To get real-time data from Workspace with .NET, you need to use Refinitiv Data Library for .Net instead. The examples are on GitHub. However, the library can't start Workspace automatically.

To start Workspace automatically, please contact the helpdesk team directly via MyAccount to verify if there is a method to start Workspace automatically or start it via a script.
