Chapter 6. Configuring Decision Server with the integrated Decision Manager controller

Note

Only make the changes described in this section if Decision Server will be managed by Decision Central and you installed Red Hat Decision Manager from the ZIP files. If you did not install Decision Central, you can use the headless Decision Manager controller to manage Decision Server, as described in Chapter 7, Installing and running the headless Decision Manager controller.

Decision Server can be managed or it can be unmanaged. If Decision Server is unmanaged, you must manually create and maintain KIE containers (deployment units). If Decision Server is managed, the Decision Manager controller manages the Decision Server configuration and you interact with the Decision Manager controller to create and maintain KIE containers.

The Decision Manager controller is integrated with Decision Central. If you install Decision Central, you can use the Execution Server page in Decision Central to interact with the Decision Manager controller.

If you installed Red Hat Decision Manager from the ZIP files, you must edit the standalone-full.xml file in both the Decision Server and Decision Central installations to configure Decision Server with the integrated Decision Manager controller.

Prerequisites

  • Decision Central and Decision Server are installed in the base directory of the Red Hat JBoss EAP installation (EAP_HOME).

    Note

    You should install Decision Central and Decision Server on different servers in production environments. However, if you install Decision Server and Decision Central on the same server, for example in a development environment, make the changes described in this section in the shared standalone-full.xml file.

  • On Decision Central server nodes, a user with the rest-all role exists.

    Procedure

    1. In the Decision Central EAP_HOME/standalone/configuration/standalone-full.xml file, uncomment the following properties in the <system-properties> section and replace <USERNAME> and <USER_PWD> with the credentials of a user with the kie-server role: 

         <property name="org.kie.server.user" value="<USERNAME>"/>
   <property name="org.kie.server.pwd" value="<USER_PWD>"/>

    2. In the Decision Server EAP_HOME/standalone/configuration/standalone-full.xml file, uncomment the following properties in the <system-properties> section. 

        <property name="org.kie.server.controller.user" value="<CONTROLLER_USER>"/>
  <property name="org.kie.server.controller.pwd" value="<CONTROLLER_PWD>"/>
  <property name="org.kie.server.id" value="<KIE_SERVER_ID>"/>
  <property name="org.kie.server.location" value="http://<HOST>:<PORT>/kie-server/services/rest/server"/>
  <property name="org.kie.server.controller" value="<CONTROLLER_URL>"/>
    3. Replace the following values:
  • Replace <CONTROLLER_USER> and <CONTROLLER_PWD> with the credentials of a user with the rest-all role.
  • Replace <KIE_SERVER_ID> with the ID or name of the Decision Server installation, for example, rhdm-7.1.0-decision_server-1.
  • Replace <HOST> with the ID or name of the Decision Server host, for example, localhost or 192.7.8.9.

  • Replace <PORT> with the port of the Decision Server host, for example, 8080.

    Note

    The org.kie.server.location property specifies the location of Decision Server.

  • Replace <CONTROLLER_URL> with the URL of Decision Central. Decision Server connects to this URL during startup.
