Troubleshooting on UNIX systems

Writing messages to log files is disabled by default on UNIX systems. You can
enable debugging or tracing functions by using the debug and trace input
parameters. The Scanner writes the debug and trace data to different log files and
uses timestamps to flag the start and end times of steps or functions. You can use
both files to correlate and troubleshoot a specific issue, function, or prerequisite
check.
Debugging log file
When you run the Prerequisite Scanner script and set the optional debug parameter,
Prerequisite Scanner outputs detailed processing information, warning and error
messages, and the scan results in the ips_output_dir/temp/prs.debug file. It contains
detailed information with each step and function that the Scanner performs in
sequence. The file also contains timestamps, including start and end times of each
function and step. The ips_output_dir/temp subdirectory also contains the interim
result1.txt and result2.txt files that provide the input to the final
ips_output_dir/result.txt file. You can use these interim files to determine issues
