You can view archived binary log files in the Log Events window.
If you do not know the session or workflow log file name and location, check the Log File Name and Log File Directory attributes on the Session or Workflow Properties tab.
If you are running the Integration Service on UNIX and the binary log file is not accessible on the Windows machine where the PowerCenter client is running, you can transfer the binary log file to the Windows machine using FTP.
In the Workflow Monitor, click Tools > Import Log.
Navigate to the session or workflow log file directory.
