Chapter 9. Configuring Decision Server Managed by Decision 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 Decision Central to manage a Decision Server instance.

Prerequisite

Users with the following roles exist:

  • In Decision 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 Decision 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.

    The location of Decision 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;

    org.kie.server.location

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

    The location of the Decision Server.

    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>

</response>

  3. Verify successful registration:

    1. Log in to Decision Central.

    2. Click Menu → Deploy → Execution Servers.

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