Launching the TN3270 Mainframe Display to Debug Applications

When you start debugging, the IDE automatically launches the TN3270 Mainframe Display specified in the IDE preferences and connects it to the enterprise server region on which your application is running.

If the TN3270 Mainframe display of choice is closed, you can open it in one of the following ways:

  1. In the Debug perspective, right-click the application thread in the Debug view.
  2. Click Relaunch.
