Run MFDEMO

Use the Rumba TN3270 emulator to run the MFDEMO application on the IMSDEMO enterprise server region.

With the IMSDEMO enterprise server region started in Enterprise Server (see the Start IMSDEMO section in the previous topic), you can now run the MFDEMO application from the Rumba TN3270 mainframe display, and add data to the IMS database.

The installation of Enterprise Developer includes the Micro Focus Rumba emulator. The Rumba TN3270 Mainframe Display is embedded within Enterprise Developer. As part of this tutorial, you use the embedded Rumba display to run the application.

Configure the TN3270 settings in Enterprise Developer

Here, you check your Enterprise Developer options and ensure that the embedded Rumba display is selected:

In the IDE, click Tools > Options.
Expand Micro Focus, and click TN3270 Display.
Ensure that Enable Display is checked and that the Rumba (Embedded) display option is selected.
Ensure that Connect automatically is checked.
Click OK.

Start the Embedded Rumba Display

In Server Explorer, right-click IMSDEMO; then select Mainframe TN3270 Display.
This opens the embedded Rumba display and connects Rumba to the IMSDEMO enterprise server using a TN3270 connection. You can see the login page of the IMSDEMO application.

Note: If at any time the Rumba embedded display is not visible, click Mainframe TN3270 Display on the Enterprise Developertoolbar.

Start the MFDEMO Application

Note: Before interacting with the Rumba display, be sure that Enterprise Server Administration is not open in an Enterprise Developer tab.

On the IMS sign-on screen, type SYSAD into both the USERID and PASSWORD fields using the Tab key to move from one to the other; then press Enter.
Press Ctrl+Shift+Z to clear the Mainframe TN3270 Display screen.
Enter MFDEMO with a trailing space.
Rumba shows the MFDEMO initial menu screen, DEMO91.
