Changing the engine type

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

About this task

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: When you install and configure 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

Using a text editor, open the file spserver.properties from the following location.
- Cluster: SPSERVER_SHARE/conf
- Standalone: SPSERVER_HOME/conf
(where SPSERVER_SHARE or SPSERVER_HOME is your Spotfire Statistics Services installation directory

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 does not run in TERR. Requires additional steps. See Configure an open-source R engine for more information. Note: In this version of Spotfire Statistics Services, 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.
