When you try to run an extract refresh on Tableau Server, the extract refresh fails, and the following error appears in the Background Tasks view:

com.tableausoftware.nativeapi.dll.DataSourceException: Invalid database name value


  • Tableau Server 
  • Extracts


One of the following steps might resolve the issue:
  • Use the UNC path to connect to the source file from which the extract is created. For more information, see UNC on MSDN.
  • Verify that the Tableau Server Run As User can access the source file from the computer running Tableau Server. For more information, see Run As Account Settings to Confirm in Tableau Help.
If the extract or the data source flat file is located in a Linux environment, work with your IT team to create a UNIX shell in order for the UNC path to work properly from a Linux computer to Tableau Server’s Window computer.


The Tableau Server Run As User is unable to access the source file.
