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.
Important: You must install the PostgreSQL driver if you want to use the built-in administrative views.
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
