Access to Legacy Applications and Data

Step 1: Configuring COMTI

To develop a COMTI component, you must have the following installed:

Windows 2000 Server or Windows 2000 Professional
IIS 5.0 with Component Services 2.0
Microsoft® Windows Client for SNA Server
Microsoft® Data Access Components (MDAC) 2.0

Additionally, the following COMTI components must be installed:

The administration component, which collects information about the user’s SNA environment.
The run-time component, which intercepts the method calls to the mainframe and uses the COMTI-created component library to perform the actual conversion and formatting of the method parameters. In addition, the run-time component interacts with SNA Server and builds packets, which are sent to the mainframe using LU 6.2 or TCP/IP.
Development tool components, featuring the Component Builder, a GUI used to create component libraries from mainframe COBOL programs.

The Component Builder can be installed as an add-in to Microsoft® Visual Basic® 5.0, and does not need to be installed on the same system as the other components. Developers who are not using Visual Basic 5.0 can use the Component Builder as a stand-alone tool.
