Troubleshooting Data Loader Operations

Available in: Enterprise, Performance, Unlimited, Developer, and Database.com Editions

If you need to investigate a problem with Data Loader, or if requested by Salesforce Customer Support, you can access log files that track the operations and network connections made by Data Loader. The log file is:

sdl.log
Contains a detailed chronological list of Data Loader log entries. Log entries marked “INFO” are procedural items, such as logging in to and out of Salesforce. Log entries marked “ERROR” are problems such as a submitted record missing a required field.

The log file can be opened with commonly available text editor programs, such as Microsoft Notepad.

You can quickly open the log file by entering %TEMP%\sdl.log in either the Run dialog or the Windows Explorer address bar.

If you are having login issues from the command line, ensure that the password provided in the configuration parameters is encrypted. If you are having login issues from the UI, you may need to obtain a new security token.
