Configuring the Insight Worker for a Simulation

The Xpress Insight Simulation Capability can be used to augment an Insight app to efficiently simulate transaction executions over different Decisioning Assets from FICO® Blaze Advisor.

In this section we will cover how to update the Insight Worker configuration to enable the simulation capability.

We will also describe how to configure the environment to provide the simulation engine access to your Blaze runtime and license to be able to simulate Blaze projects. For the simulation capability to be made available to your application you need to configure the path to the simulation engine Java library, and we recommend to also set the path to the Java runtime. It is important to use the same Java version as the Insight Worker. The supported Java runtimes are listed on Prerequisites.

When executing a simulation. For this reason, it is a good practice to set the JAVA_HOME to a known location to reduce the risk of using an incompatible Java runtime. We have summarized these recommendations in the following configuration snippet that can be used to augment the application.properties file of the Insight worker:
  • insight.worker.execution.environment.XPRESS_INSIGHT_LIB=<path_to_rules_directory>

    XPRESS_INSIGHT_LIB Points to the location of the simulation.jar. This parameter is automatically set during the Insight 5 Worker installation.

  • insight.worker.execution.environment.JAVA_HOME=/opt/amazon-corretto-11.jdk/bin

    JAVA_HOME points to the folder that contains a Java runtime that supports Java 11.

Once the configuration file has been updated, please restart the Insight Worker.

Note: As an alternative to configuring the environment variables through this file, it is also possible to configure them directly in the model_resources/ rule_client_config.json file that is part of your application. An example configuration file is provided with the Insight Python Simulation Example that is part of the distribution.
