Run MFDEMO

Walks you through the process of using the Rumba+ Desktop 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+ Desktop TN3270 mainframe display, and add data to the IMS database.

Configure the TN3270 settings in Enterprise Developer

Here, you check your Enterprise Developer options and ensure that the embedded Rumba+ Desktop 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 Apply and Close.

Start the Rumba Mainframe Display View

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

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

Start the MFDEMO application

Note: Before interacting with the Rumba+ Desktop 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 Rumba Mainframe Display screen.
Enter MFDEMO with a trailing space.
Rumba+ Desktop shows the MFDEMO initial menu screen, DEMO91.

Add data

In the sections that follow, each set of instructions includes a screen shot showing the terminal emulator with required fields in green and red.

Tip: To navigate between fields on a terminal emulator screen, press Tab to move to the next field, and Shift+Tab to move to the previous field.

Create a TESTDEPT table

In the FUNCTION CODE field, type A to select the <A>DD function.
This action advances your cursor to the TABLE-ID field.
In the TABLE-ID field, type TESTDEPT.
Press Enter.
This action advances you to the DEMO92 input screen.

Input records

Complete the following fields as indicated:

DESCRIPTION	`A TABLE OF TEST DEPARTMENTS`
NUMBER OF CHARACTERS IN ELEMENT KEY	`20`
NUMBER OF CHARACTERS IN ELEMENT	`50`
PASSWORD PROTECT	`N`

Tab to the first entry field under ELEMENT KEY; then add the following records:

ELEMENT KEY	ELEMENT VALUE/DESCRIPTION
`123`	`DEPARTMENT 123`
`234`	`DEPARTMENT 234`

Tab to the RETURN field; then type X.
Press Enter to return to the main menu.

Add an additional record

In the FUNCTION CODE field, type C to select the <C>HANGE function.
This action advances your cursor to the TABLE-ID field.
In the TABLE-ID field, type TESTDEPT.
Press Enter.
This action advances you to the DEMO92 input screen.

Tab to the first field in the third row under FUNC; then add the following record:

FUNC	ELEMENT KEY	ELEMENT VALUE/DESCRIPTION
A	`345`	`DEPARTMENT 345`

Tab to the RETURN field; then type X.

Add the TESTERS table and records

Using the same methods as you did to create the TESTDEPT table and add records, add the TESTERS table using these values:

DESCRIPTION	`A TABLE OF TESTERS`
NUMBER OF CHARACTERS IN ELEMENT KEY	`20`
NUMBER OF CHARACTERS IN ELEMENT	`50`
PASSWORD PROTECT	`N`

Then add the following records:

ELEMENT KEY	ELEMENT VALUE/DESCRIPTION
`JOHN SMITH`	`IMS DC TEST TECHNICIAN`
`JANE JONES`	`IMS DB TEST TECHNICIAN`

Press Enter to return to the main menu.

Exit MFDEMO

On the main menu, type E into the FUNCTION CODE field; then press Enter.
This action takes you to the TRANCODE - MFDEMO - ENDED screen.
Click Disconnect on the Rumba+ toolbar to disconnect from the database.

This concludes the tutorial.
