To enable Sybase IQ tracing, add the following parameters to the IQ start-up command line:
-zr ALL -zo <zr_log_file>
where <zr_log_file> is the path and name for the .zr trace log file. This turns on extensive tracing within the Sybase IQ server. Additionally, you can check the standard Sybase IQ database log .iqmsg.
