What is the range of ports reserved for dynamic mapping of Tableau processes?

The range of ports reserved for dynamic mapping of Tableau processes is indeed 8000 to 9000. This port range is used by Tableau Server to facilitate communication between its various components as well as user requests. When Tableau Server is installed, it dynamically allocates these ports for different processes running on the server, such as background tasks, extract refreshes, and other services. This allows for flexibility in load balancing and ensures that multiple processes can run concurrently without interference.

The importance of having a dedicated port range for dynamic mapping lies in the need for seamless data flow and communication among the server components, which can include Tableau Application Server, backgrounder, data engine, and others. Users accessing Tableau performance via web or mobile clients communicate through these ports, which also helps isolate Tableau traffic from other application traffic on the server.

Other ranges of ports may serve different functionalities or applications, but the 8000-9000 range is specifically designed for dynamic allocation within the Tableau ecosystem.
