Micro Focus Enterprise Developer 2.3 for Eclipse > Welcome > Getting Started > Mainframe Tutorials > Tutorial: IMS > Running the IMS Application

Running the IMS Application

The IMS application requires that you use a 3270 terminal emulator. The installation of Enterprise Developer includes the Micro Focus Rumba emulator. Rumba is available as a standalone application, Rumba Desktop, and is also available as a TN3270 Mainframe Display embedded within the IDE. As part of this tutorial, you are going to use the embedded display to run the application.

Configuring the TN3270 Settings in the IDE

To check the IDE preferences and ensure that the embedded Rumba display is selected:

In the IDE, click Window > Preferences.
Expand Micro Focus > Enterprise Server, and click TN3270.
Ensure that Enable display, Rumba (Embedded) and Connect automatically are all selected.
Click OK.

Starting the Rumba Mainframe Display View

In Server Explorer, right-click IMSDEMO and click Show TN3270 Display.
This opens the Rumba Mainframe Display view and establishes a 3270 terminal connection in Rumba to enable it to connect to the IMSDEMO enterprise server. You can see the login page of the IMSDEMO application.

Note: If the Rumba Mainframe Display view does not connect automatically, click (Connect).

Starting the Demonstration Application

On the IMS sign-on screen, specify a user ID and password, and then press Enter.
If you have not configured Enterprise Server security, you can use the user SYSAD with password SYSAD.
Clear the screen of your terminal emulator - in the Rumba Mainframe Display view, press CTRL+SHIFT+Z.
Enter MFDEMO (with a trailing space).
The following sections describe the demonstration program and how you navigate through its screens.

Start your TN3270 emulator.

Specify the following connection information.

Note that field names could vary depending on the 3270 emulator you are using.

Field	Value
Host name	The dnsname or TCP/IP @ of the computer the enterprise server is running on. This is localhost on your machine.
Port	The port number you specified for the 3270 listener when creating the IMS-enabled enterprise server. On versions of Windows Vista and later, if you experience issues connecting to localhost, connect to 127.0.0.1 instead.
