Access to Legacy Applications and Data

Scenario Two: Extending Transactions with COMTI

When deployed in the Windows 2000 Server–based environment, COMTI can extend transactions to include mainframe transaction processing programs running on CICS and IMS.

A developer can use the following steps in order to connect a Windows 2000 Server–based Web site to an existing COBOL transaction processing program. Doing so will make legacy data available to scripts in ASP pages. In this scenario, additional tasks are needed in order to extend transactions that are under the control of CICS.

Like the previous scenario, this scenario also involves six main steps:

Step 1: Configuring COMTI
Step 2: Defining Required Methods and Parameters
Step 3: Writing the Application
Step 4: Testing the Application
Step 5: Deploying Application Components
Step 6: Maintaining the Application
