MHP trace information is collected when these specifications are completed. The information can be edited and output to standard output by entering the online tester's utotrcout command.

The output format follows TP1/Server Base online tester specifications. No trace information is output for the following functions.

• dc_mcf_open function
• dc_mcf_close function
• dc_mcf_mainloop function
• dc_mcf_regster function

MHP trace information is output to the $DCDIR/spool/uto/test-user-ID directory. The test user ID in the pathname is the ID specified in the -u option of the mcfutfst command.

There are two MHP trace files, trace1 and trace2. These files are swapped if the contents written to a file exceed the value specified in the max_trace_file_size operand of the tester service definition. A message reports that the files were swapped when one file became full. When this message is output, copy the contents of the full trace file to another file, then delete the full trace file.

See Section 3.1 System definitions for the online tester for information on the system service configuration definition, tester service definition, and user service definition. For details on the utotrcout command, see Section 5.1 Operating commands for running tests.
