Trace information can be collect for a test MHP so that MHP operation can be checked. However, the TP1/Server Base online tester must also be used.

To use this facility, specify the test user ID in the -u option of the command for the MCF online tester use declaration (mcfutfst), and trace in the -e option of the test start command (mcftules, mcfauaps, or mcftusgs).
