Changing the engine type

You can change the engine that Spotfire Statistics Services uses as part of your post-installation configuration.

By default, during installation, the engine type is set to TERR. Changing the engine type is optional. You can specify only one engine type.

Important: Remember that when installing and configuring Spotfire Statistics Services to use a statistical engine, consider the configurations and strategies to restrict access. See Recommendations for safeguarding your environment for detailed information.

Procedure

  1. Browse to the directory SPSERVER_HOME/conf/ (where SPSERVER_HOME is your server installation directory).
  2. Using a text editor, open the file spserver.properties.
  3. Locate the property engine.type, and set it to the value to use.
    Engine Type Description
    TERR TERR engine. The default. Provided with your Spotfire Statistics Services installation.
    R Open-source R engine. Use this engine if developers are deploying R packages to the service, and the packages contain R code that will not run in TERR. Requires additional steps. See Configure an open-source R engine for more information.
    Note: In Spotfire Statistics Services version 10.10.1, open-source R is configurable.
    SAS SAS® engine. Requires additional steps. See Configure a SAS engine for more information.
    MATLAB MATLAB® engine. Requires additional steps. See Configure a MATLAB engine for more information.
    When you update or change the engine.type property, you must restart the server to initiate the deployment. For clusters, when the server starts, the engine is copied from its location and deployed to each node in the cluster. For more information about the location of the engines, see Engine location.
