1.2.3 Trace log
A trace log contains trace information that can be used in investigating how a problem has occurred and in determining how time was required to execute each process when a problem has occurred.
The JP1/AJS3 trace information is output to multiple trace log files. The internal format of each trace log file is not public information. In addition, a text editor cannot be used to view the files because the files are binary files.
