  4. Click one of the options to specify the integrated TN3270 display to use:
    • Host Access for the Cloud - when selected, an HACloud session is used to run or debug applications.
      Restriction: This option does not support regions inside Enterprise Server for .NET, or connecting to Docker containers.
    • Rumba (Desktop) - if you have Micro Focus Rumba+ Desktop installed, click this to use a Mainframe Display session when running or debugging applications. You can invoke Rumba+ Desktop from the IDE and start the application in a mainframe session. The session connects to the server automatically when you open the display to run the application or when you start debugging.
      • Use project specific Rumba session profile (if exists) - enables the use of a preconfigured session defined in the associated project when Rumba+ Desktop is launched.
    • Reflection Desktop - if you have Micro Focus Reflection Desktop 17 installed, click this to use a TN3270 session when running or debugging applications. You can invoke Reflection Desktop from the IDE and start the application in a 3270 terminal. The session connects to the server automatically when you open the display to run the application or when you start debugging.
      Restriction: This option does not support regions inside Enterprise Server for .NET, or connecting to Docker containers.
      • Use project specific Reflection session document (if exists) - enables the use of a preconfigured session defined in the associated project when Reflection Desktop is launched.
    • External - click this to specify another TN3270 mainframe emulator.
