Customizing JDBC Connections

Publiseringsdato: Feb 19, 2026
Oppgave
Some Tableau named connectors, such as Amazon Athena, SAP HANA, and Oracle use the JDBC standard instead of ODBC. There are two ways to connect using JDBC, Use a TDC file, or Use a PROPERTIES file.

How can users modify JDBC connections and gather driver logs?

JDBC connection options can be modified through the use of a .properties file. This is a plain text document containing key-value pairs for each connection parameter. However, please note that this file should not be saved in a UTF-8 with BOM character encoding - this encoding adds characters to the beginning of a file and interferes with Tableau applying the customizations.

Each key-value pair should be on its own line with no delimiter - refer to the examples attached to this article. After saving the document as either saphana.properties or athena.properties (as appropriate), place it in the My Tableau Repository/Datasources folder.

To enable a .properties file for Tableau Server, it must be placed on all Server nodes in the following directory: 

  • tabsvc/vizqlserver/Datasources for Windows
  • /var/opt/tableau/tableau_server/data/tabsvc/vizqlserver/Datasources/ for Linux

If you are using Tableau Prep Conductor, make sure the file is placed in the following directories as well:

  • ProgramData\Tableau\Tableau Server\data\tabsvc\flowprocessor\Datasources for Windows
  • ProgramData\Tableau\Tableau Server\data\tabsvc\flowminerva\Datasources for Windows 2021.2 and later
  • ProgramData\Tableau\Tableau Server\data\tabsvc\flowqueryservice\Datasources for Windows versions 2021.1 and earlier
  • /var/opt/tableau/tableau_server/data/tabsvc/flowprocessor/Datasources/ for Linux
  • /var/opt/tableau/tableau_server/data/tabsvc/flowminerva/Datasources/ for Linux versions 2021.2 and later
  • /var/opt/tableau/tableau_server/data/tabsvc/flowqueryservice/Datasources/ for Linux versions 2021.1 and earlier

For Virtual Connections:

  • ProgramData\Tableau\Tableau Server\data\tabsvc\minerva\Datasources for Windows
  • /var/opt/tableau/tableau_server/data/tabsvc/minerva/Datasources/ for Linux


Further connections to that data source type will have the option values included in the query URL.

In addition to the options in the links above, proxy information can be specified using the keys proxy_host and proxy_port, as described in this KB article Unable to Connect to Athena via Proxy Server

Any '\' characters in the athena.properties file, such as in filepaths, must be escaped. Instead of C:\Users\username, you would use C:\\Users\\username.
