By default, when you configure a workflow or session to create log files, the Integration Service creates one log file for the workflow or session. The Integration Service overwrites the log file when you run the workflow again.
To create a log file for more than one workflow or session run, configure the workflow or session to archive logs in the following ways:
Archive text log files by run. Configure a number of text logs to save.
By time stamp
. Archive binary logs and text files by time stamp. The Integration Service saves an unlimited number of logs and labels them by time stamp. When you configure the workflow or session to archive by time stamp, the Integration Service always archives binary logs.
When you run concurrent workflows with the same instance name, the Integration Service appends a timestamp to the log file name, even if you configure the workflow to archive logs by run.
