Chapter 6. Downloading and installing the headless Decision Manager controller

Procedure

1. Navigate to the Software Downloads page in the Red Hat Customer Portal (login required), and select the product and version from the drop-down options:

   • Product: Decision Manager
   • Version: 7.2
2. Download Red Hat Decision Manager 7.2.0 Add Ons (the rhdm-7.2.0-add-ons.zip file).
3. Unzip the rhdm-7.2.0-add-ons.zip file. The rhdm-7.2-controller-jws.zip file is in the unzipped directory.
4. Extract the rhdm-7.2-controller-jws.zip archive to a temporary directory. In the following examples this directory is called TEMP_DIR.

5. Copy the TEMP_DIR/rhdm-7.2-controller-jws.zip/controller.war directory to the JWS_HOME/tomcat/webapps directory.

   Note

   Ensure the names of the Red Hat Decision Manager deployments you are copying do not conflict with your existing deployments in the Red Hat JBoss Web Server instance.

6. Remove the .war extensions from the controller.war folder.
7. Copy the contents of the TEMP_DIR/rhdm-7.2-controller-jws/SecurityPolicy/ directory to JWS_HOME/bin. When asked to overwrite files, select Yes.

8. Add the kie-server role and user to the JWS_HOME/tomcat/conf/tomcat-users.xml file. In the following example, <USERNAME> and <PASSWORD> are the user name and password of your choice:

   <role rolename="kie-server"/>
   <user username="<USER_NAME>" password="<PASSWORD>" roles="kie-server"/>

9. Complete one of the following tasks in the JWS_HOME/tomcat/bin directory of the instance running Decision Server:

   • On Linux or UNIX, create the setenv.sh file with the following content:

     CATALINA_OPTS="-Xmx1024m
      -Dorg.jbpm.server.ext.disabled=true
      -Dorg.jbpm.ui.server.ext.disabled=true
      -Dorg.jbpm.case.server.ext.disabled=true
      -Dorg.kie.server.controller.user=<CONTROLLER_USER>
      -Dorg.kie.server.controller.pwd=<CONTROLLER_PWD>
      -Dorg.kie.server.id=<KIE_SERVER_ID>
      -Dorg.kie.server.location=http://<HOST>:<PORT>/kie-server/services/rest/server
      -Dorg.kie.server.controller=http://<HOST>:<PORT>/controller/rest/controller"

     Copy to Clipboard

   • On Windows, add the following content to the setenv.bat file:

     set CATALINA_OPTS= -Xmx1024m
      -Dorg.jbpm.server.ext.disabled=true
      -Dorg.jbpm.ui.server.ext.disabled=true
      -Dorg.jbpm.case.server.ext.disabled=true
      -Dorg.kie.server.controller.user=<CONTROLLER_USER>
      -Dorg.kie.server.controller.pwd=<CONTROLLER_PWD>
      -Dorg.kie.server.id=<KIE_SERVER_ID>
      -Dorg.kie.server.location=http://<HOST>:<PORT>/kie-server/services/rest/server
      -Dorg.kie.server.controller=http://<HOST>:<PORT>/controller/rest/controller

     Copy to Clipboard

10. In the JWS_HOME/tomcat/bin directory of the instance running the headless Decision Manager controller, create a readable setenv.sh file with the following content:

    CATALINA_OPTS="-Dorg.kie.server.user=<USERNAME> -Dorg.kie.server.pwd=<USER_PWD>"

11. To start the headless Decision Manager controller, enter one of the following commands in the JWS_HOME/tomcat/bin directory:

    • On Linux or UNIX-based systems:

      $ ./startup.sh

      Copy to Clipboard

    • On Windows:

      startup.bat

      Copy to Clipboard
12. After a few minutes, review the JWS_HOME/tomcat/logs directory and correct any errors.

13. To verify that the headless Decision Manager controller is working on Red Hat JBoss Web Server, enter the following command. In this command, replace <CONTROLLER> and <CONTROLLER_PWD> with the values in the tomcat-users.xml file. The output of this command provides information about the Decision Server instance.

    curl -X GET "http://<HOST>:<PORT>/controller/rest/controller/management/servers" -H  "accept: application/xml" -u '<CONTROLLER>:<CONTROLLER_PWD>'
