Configure a workflow or session to write log events to log files in the workflow or session properties. The Integration Service writes information about the workflow or session run to a text file in addition to writing log events to a binary file. If you configure workflow or session properties to create log files, you can open the text files with any text editor or import the binary files to view logs in the Log Events window.

By default, the Integration Service writes log files based on the Integration Service code page. If you enable the LogInUTF8 option in the Advanced Properties for the Integration Service, the Integration Service writes to the logs using the UTF-8 character set. If you configure the Integration Service to run in ASCII mode, it sorts all character data using a binary sort order even if you select a different sort order in the session properties.

Optimize performance by disabling the option to create text log files.
