Server Process Limits

Tableau Server on Windows now includes Tableau Services Manager (TSM), which replaces the Configuration Utility and the tabadmin command line tool. If you need help for an earlier version of Tableau Server, see the Tableau Help page.

When you reconfigure processes for Tableau Server, there is a limit to the amount that you can increase the number of process instances. By default, the limit is set to eight. If your machine has enough RAM and CPU cores, and you want to go above this limit, you can change the limit using the service.max_procs configuration option. For each process instance, Tableau recommends that the machine running the process have at least 1 GB of RAM and 1 logical CPU core.

To change the maximum number of processes allowed:

  1. Type the following command, where number is the maximum number of process instances you want to allow:

    tsm configuration set -k service.max_procs -v <number>

    For example:

    tsm configuration set -k service.max_procs -v 10

  2. Next type:

    tsm pending-changes apply

    The pending-changes apply command displays a prompt to let you know this will restart Tableau Server if the server is running. The prompt displays even if the server is stopped, but in that case there is no restart. You can suppress the prompt using the --ignore-prompt option, but this does not change the restart behavior. For more information, see tsm pending-changes apply.
