Gen--Override the default trace environment variables

A client transaction can transfer the host and port of the client that is executing the transaction. By providing this information, the server can establish communication with the Diagram Trace Utility running on that client workstation. To trace the server for each transaction initiated from a client, use the client's Diagram Trace Utility.

Follow these steps:

1. Build the server application that has been generated with trace (as before).
2. Leave the trace environment variables within the application.ini file that is located in the server application's model directory commented out.
3. Start your servers using tmboot.
4. Invoke the Diagram Trace Utility on your client workstation.
5. Edit the application.ini file residing in your client application's executables directory.
6. Uncomment and set the trace environment variables. You can use ‘localhost’ for the TRACE_HOST variable.
7. Execute your client application.

   The Diagram Trace Utility on the client workstation will be used to trace the server for each transaction initiated from that client.
