Chapter 5. Installing Red Hat Decision Manager from ZIP files

The Red Hat Decision Manager ZIP files (one for Business Central and one for Decision Server) do not require a graphical user interface so you can install Red Hat Decision Manager using SSH.

Note

You should install Business Central and the Decision Server on different servers in production environments.

For information about installing the headless Decision Manager controller, see Chapter 10, Installing and running the headless Decision Manager controller.

5.1. Installing Business Central from the ZIP file

Business Central is a web console that enables you to create, manage, and edit your rules and related assets in a unified web-based environment.

Prerequisites

  • A backed-up Red Hat JBoss EAP installation version 7.2 is available. The base directory of the Red Hat JBoss EAP installation is referred to as EAP_HOME.
  • Sufficient user permissions to complete the installation are granted.
  • The following file is downloaded as described in Chapter 3, Downloading the Red Hat Decision Manager installation files:

    rhdm-7.6.0-decision-central-eap7-deployable.zip

Procedure

  1. Extract the rhdm-7.6.0-decision-central-eap7-deployable.zip file to a temporary directory. In the following examples this directory is called TEMP_DIR.
  2. Copy the contents of the TEMP_DIR/rhdm-7.6.0-decision-central-eap7-deployable/jboss-eap-7.2 directory to EAP_HOME. When prompted, merge or replace files.

    Warning

    Ensure the names of the Red Hat Decision Manager deployments you copy do not conflict with your existing deployments in the Red Hat JBoss EAP instance.

5.2. Installing Decision Server from the ZIP file

Decision Server provides the runtime environment for business assets and accesses the data stored in the assets repository (knowledge store).

Prerequisites

  • A backed-up Red Hat JBoss EAP installation version 7.2 is available. The base directory of the Red Hat JBoss EAP installation is referred to as EAP_HOME.
  • Sufficient user permissions to complete the installation are granted.
  • The following file is downloaded as described in Chapter 3, Downloading the Red Hat Decision Manager installation files:

    rhdm-7.6.0-kie-server-ee8.zip

Procedure

  1. Extract the rhdm-7.6.0-kie-server-ee8.zip archive to a temporary directory. In the following examples this directory is called TEMP_DIR.
  2. Copy the TEMP_DIR/rhdm-7.6.0-kie-server-ee8/kie-server.war directory to EAP_HOME/standalone/deployments/.

    Warning

    Ensure the names of the Red Hat Decision Manager deployments you copy do not conflict with your existing deployments in the Red Hat JBoss EAP instance.

  3. Copy the contents of the TEMP_DIR/rhdm-7.6.0-kie-server-ee8/rhdm-7.6.0-kie-server-ee8/SecurityPolicy/ to EAP_HOME/bin. When asked to overwrite files, click Replace.
  4. In the EAP_HOME/standalone/deployments/ directory, create an empty file named kie-server.war.dodeploy. This file ensures that Decision Server is automatically deployed when the server starts.

5.3. Creating users

Before you can log in to Business Central or Decision Server, you must create users. This section shows you how to create a Business Central user with the admin, rest-all, and kie-server roles and a Decision Server user that has the kie-server role. For information about roles, see Chapter 2, Red Hat Decision Manager roles and users.

Prerequisites

  • Red Hat Decision Manager is installed in the base directory of the Red Hat JBoss EAP installation (EAP_HOME).

Procedure

  1. In a terminal application, navigate to the EAP_HOME/bin directory.
  2. Create a user with the admin, rest-all, and kie-server roles.

    Note

    Users with the admin role are Business Central administrators. Users with rest-all role can access Business Central REST capabilities. Users with the kie-server role can access Decision Server (KIE Server) REST capabilities.

    In the following command, replace <username> and <password> with the user name and password of your choice.

    $ ./add-user.sh -a --user <USERNAME>  --password <PASSWORD> --role admin,rest-all,kie-server
    Note

    Make sure that the specified user name is not the same as an existing user, role, or group. For example, do not create a user with the user name admin.

    The password must have at least eight characters and must contain at least one number and one non-alphanumeric character, but not & (ampersand).

  3. Create a user with the kie-server role that you will use to log in to Decision Server.

    $ ./add-user.sh -a --user <USERNAME>  --password <PASSWORD> --role kie-server
  4. Make a note of your user names and passwords.

    Note

    If you installed Business Central and Decision Server in the same server instance, you can create a single user that has both of these roles:

    $ ./add-user.sh -a --user <USERNAME>  --password <PASSWORD> --role admin,rest-all,kie-server

    You should install Business Central and Decision Server on different servers in production environments.

5.4. 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 Business Central and you installed Red Hat Decision Manager from the ZIP files. If you did not install Business Central, you can use the headless Decision Manager controller to manage Decision Server, as described in Chapter 10, 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 Business Central. If you install Business Central, you can use the Execution Server page in Business 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 Business Central installations to configure Decision Server with the integrated Decision Manager controller.

Prerequisites

Procedure

  1. In the Business 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-7.6.0-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 Business Central. Decision Server connects to this URL during startup.

      • If you installed Business Central using the installer or Red Hat JBoss EAP zip installations, <CONTROLLER_URL> has this format:

        http://<HOST>:<PORT>/decision-central/rest/controller

      • If you are running Business Central using the standalone.jar file, <CONTROLLER_URL> has this format:

        http://<HOST>:<PORT>/rest/controller
