Tableau connectors require a driver to talk to the database. Before you can connect to data sources from Tableau Server, you must install drivers for the data sources you want to connect to. You can find driver links and installation instructions for all the supported connectors on the Driver Download page.
Install drivers in a cluster
You need to install the drivers for your data sources on the initial node in a Tableau Server cluster. If you install Tableau Server on multiple nodes, you must also install drivers on any node that runs any of the following processes:
- Application Server (Vizportal)
- Data Server
- VizQL Server
