Chapter 13: IMS Installation Verification

IMS Option provides two demonstration applications. These are installed in the \mfuser\projects\gsdemo\imsdemo\source folder. You should run these demonstrations if you suspect your applications are not running correctly as a result of an installation problem.

13.1 MFDEMO

MFDEMO is a system which captures and maintains table data. The tables are organized by table element within table name. The tables eliminate the program maintenance associated with traditional data division tables. The following source members are used by this application:

13.2 TESTMENU

The TESTMENU system includes the following features:

• Conversational transactions

• Message switching

• Logical paging

• Secondary indexing

To demonstrate logical paging, the program reads a secondary index many times to ensure multiple pages are output. In addition, it uses the table data maintained by the MFDEMO application. The Gen source used by this application is:

13.3 Before Running the Programs

Follow the steps below before you run MFDEMO and TESTMENU. See the chapter IMS Applications in your Getting Started for information on how to perform these steps.

1. Create a project. Use \mfuser\projects\gsdemo\imsdemo as the working folder for the project.

2. Add files to the project in the \mfuser\projects\gsdemo\imsdemo\source folder

3. Build the project

4. Add a transaction code for MFDEMO using the values shown below:

   Program Type	MPP
   Trancode Name	MFDEMO
   PSB Name	DEMO001T
   Program Name	DEMO001T
   SPA Size	0
   Process Limit Count	5
   Max Seg No	999

5. Define transactions for TESTMENU and TESTMAIN using the values shown below:

   Program Type	MPP	MPP
   Trancode Name	TESTMENU	TESTMAIN
   PSB Name	TEST001T	TEST002T
   Program Name	TEST001T	TEST002T
   SPA Size	1000	1000
   Process Limit Count	99	99
   Max Seg No	999	999

6. Select Start Debugging on the Debug menu

7. Select MFDEMO in the Command or transaction code entry field

8. Click OK

9. Select Run on the Debug menu.

   You see an interactive screen which is described in the following section.

Notes:

• Before you run the MFDEMO demo application you need to zeroload the database DEMO03DD

• Before running the TESTMENU demo application you need to:
  • Zeroload the TEST01DD database

    For information on how to zeroload a database, click Help Topics on the Mainframe Express Help menu, then on the Contents tab click IMS Option, Managing and Running IMS Applications, How to Zeroload a database.
