Chapter 9. Configuring Decision Server Managed by Business Central

Warning

This section provides a sample setup that you can use for testing purposes. Some of the values are unsuitable for a production environment, and are marked as such.

Use this procedure to configure Business Central to manage a Decision Server instance.

Prerequisites

  • Users with the following roles exist:

    • In Business Central, a user with the role rest-all
    • On the Decision Server, a user with the role kie-server
Note

In production environments, use two distinct users, each with one role. In this sample situation, we use only one user named controllerUser that has both the rest-all and the kie-server roles.

Procedure

  1. Set the following JVM properties.

    The location of Business Central and the Decision Server may be different. In such case, ensure you set the properties on the correct server instances.

    • On Red Hat JBoss EAP, modify the <system-properties> section in:

      • EAP_HOME/standalone/configuration/standalone*.xml for standalone mode.
      • EAP_HOME/domain/configuration/domain.xml for domain mode.

    PropertyValueNote

    org.kie.server.id

    default-kie-server

    The Decision Server ID.

    org.kie.server.controller

    http://localhost:8080/decision-central/rest/controller

    The location of Business Central.

    org.kie.server.controller.user

    controllerUser

    The user name with the role rest-all as mentioned in the previous step.

    org.kie.server.controller.pwd

    controllerUser1234;

    The password of the user mentioned in the previous step.

    org.kie.server.location

    http://localhost:8080/kie-server/services/rest/server

    The location of the Decision Server.

    Table 9.2. JVM Properties for Business Central Instance

    PropertyValueNote

    org.kie.server.user

    controllerUser

    The user name with the role kie-server as mentioned in the previous step.

    org.kie.server.pwd

    controllerUser1234;

    The password of the user mentioned in the previous step.

  2. Verify the successful start of the Decision Server by sending a GET request to http://SERVER:PORT/kie-server/services/rest/server/. Once authenticated, you get an XML response similar to this: 

    <response type="SUCCESS" msg="Kie Server info">
    <kie-server-info>
        <capabilities>KieServer</capabilities>
        <capabilities>BRM</capabilities>

        <capabilities>BPM-UI</capabilities>
        <capabilities>BRP</capabilities>
        <capabilities>DMN</capabilities>
        <capabilities>Swagger</capabilities>
        <location>http://localhost:8230/kie-server/services/rest/server</location>

    </kie-server-info>
</response>

  3. Verify successful registration:

    1. Log in to Business Central.

    2. Click Menu → Deploy → Execution Servers.

      If registration is successful, you can see the registered server ID.

9.1. Configuring Smart Router for TLS support

You can now configure Smart Router (previously, KIE Server Router) for TLS support to allow HTTPS traffic.

Procedure

  • Open a terminal and enter the following command to start the smart router with TLS support: 

    java -Dorg.kie.server.router.tls.keystore=PATH_TO_YOUR_KEYSTORE
     -Dorg.kie.server.router.tls.keystore.password=YOUR_KEYSTORE_PASSWD
     -Dorg.kie.server.router.tls.keystore.keyalias=YOUR_KEYSTORE_ALIAS
     -jar kie-server-router-proxy-YOUR_VERSION.jar

    Replace PATH_TO_YOUR_KEYSTORE, YOUR_KEYSTORE_PASSWD, YOUR_KEYSTORE_ALIAS, and YOUR_VERSION with the relevant data.
