Troubleshooting Data Loader Operations

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 two log files are:

sdl.log

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

sdl_out.log

A supplemental log that contains additional information not captured in sdl.log. For example, it includes log entries for the creation of proxy server network connections.

These files can be opened with commonly available text editor programs, such as Microsoft Notepad.

You can quickly open these files by entering %TEMP%\sdl.log and %TEMP%\sdl_out.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.
