  • Tableau Desktop 
  • IBM DB2 on iSeries platform


  •  Connect to DB2 using the generic ODBC connection (Other Databases (ODBC))While it may be possible to connect to DB2 using the generic ODBC data connection, success often varies and full compatibility with Tableau features cannot be guaranteed. For more information about the capabilities and limitations of connecting to unsupported data sources via generic ODBC connections, see the following articles: 
  • Mirror the data source onto a supported data source. When working with DB2 data sources on the iSeries platform, mirror the data source onto a supported data source like pSeries or xSeries platforms, and then connect to the database using the native DB2 data connection.


Connecting to IBM DB2 is not supported on iSeries platforms.
