TuxJES trace messages are stored in TuxJES trace file. By default, TuxJES trace file is stored in ${APPDIR}/Logs directory; before running Batch Runtime, you can change the directory by setting the environment variable JES_TRACE_PATH.

There are four TuxJES trace messages levels: ERROR, WARN, INFO, and DEBUG. WARN is used by default. You can use environment variable JESTRACE to set the TuxJES trace message level, or use command artjesadmin to dynamically change it, determining which level of messages will be displayed.

For more information, see Tracing TuxJES and artjesadmin.
