By default Commence runs in normal trace mode (/trace=0). Internal filenames and detailed error messages are generally hidden in this mode. The output is stored in the active.log file found in the Commence data directory.

If it becomes necessary to troubleshoot an error then a more detailed trace level (/trace=1) is needed.  This intermediate level is usually detailed enough to diagnose most errors.

The most verbose level of trace (/trace=2) creates so much additional output that the log file may become difficult to read or may be truncated too quickly. This level should be reserved for performance issues when it is necessary to track the activity down to which specific files are being read and modified. Additional steps should also be taken to increase the maximum size of the active.log file so that enough troubleshooting information can be stored in the log files.

Using /Trace=#  syntax you can specify various tracing modes. 

• /Trace=0 ;normal mode that Commence uses when no option is specified
• /Trace=1 ;generates additional output
• /Trace=2 ;includes details from mode 1 plus performance output

• Commence RM (all versions)
