COM Transaction Integrator (COMTI) version 1.0, a feature of Microsoft® SNA Server 4.0, is capable of generating Visual Studio Analyzer events. You can use these events to determine when and where a COM request has been forwarded to the mainframe for processing. Although COMTI components look like regular COM components, COMTI events indicate when the actual request has been sent to a mainframe CICS or Information Management System (IMS) program for processing and will indicate when that request comes back to the Microsoft® Windows NT® Server. If the return event does not occur, it indicates a problem on the remote mainframe.
Other Microsoft-supplied technologies are also capable of generating Visual Studio Analyzer events; see Microsoft Components That Generate Visual Studio Analyzer Events for a complete list.
