The Trace Server You can use the Exchange/SNA trace server to log the communication between your
program and the host system. To use the trace server with your programs, follow the
steps below:
1. Start the Exchange/SNA command interpreter.
2. Start a named line server or connect to an existing line server using the CONNECT
command.
3. Start the trace server using the TRACE command.
4. Disconnect and exit from the command interpreter.
The Exchange/SNA trace server is now running and logging the communications
handled by the line server you connected to in Step 2. To log your program’s
communications with the host system, have your program use subdevices supported
by this line server.
To stop the trace server, start the Exchange/SNA command interpreter, connect to the
same line server again, and use the TRACE command to stop the trace server. Use the
DUMP command to format and list the trace of your program’s communications.
