Chapter 3. Using the Red Hat Decision Manager installer

Procedure

1. In a terminal window, navigate to the directory where you downloaded the installer JAR file and enter the following command:

   java -jar rhdm-installer-7.8.0.jar

   Copy to Clipboard Toggle word wrap
   Note

   When running the installer on Windows, you may be prompted to provide administrator credentials during the installation. To prevent this requirement, add the izpack.mode=privileged option to the installation command:

   java -Dizpack.mode=privileged -jar
   rhdm-installer-7.8.0.jar

   Furthermore, when running the installer on a 32-bit Java virtual machine, you might encounter memory limitations. To prevent this issue, run this command:

   java -XX:MaxHeapSize=4g -jar
   rhdm-installer-7.8.0.jar

   Copy to Clipboard Toggle word wrap

   The graphical installer displays a splash screen and a license agreement page.

2. Click I accept the terms of this license agreement and click Next.
3. Specify the Red Hat JBoss Web Server 5.3.1 server home where you want to install Red Hat Decision Manager and click Next.

4. Select the components that you want to install and click Next.

   You cannot install Business Central on Red Hat JBoss Web Server. You can only install it on Red Hat JBoss EAP. However, you can install KIE Server and the headless Decision Manager controller on Red Hat JBoss Web Server. The headless Decision Manager controller is used to manage KIE Server. Install the headless Decision Manager controller if you plan to manage multiple KIE Server instances.

5. Create a user and click Next. By default, if you install both Business Central and KIE Server in the same container the new user is given the admin, kie-server, and rest-all roles. If you install only KIE Server, the user is given the kie-server role. The kie-server role is required to access KIE Server REST capabilities.

   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).

   Make a note of the user name and password. You will need them to access Business Central and KIE Server.

6. On the Installation Overview page, click Next to start the installation. The Installation Overview page lists the components that you will install.
7. When the installation has completed, click Next.
8. When Processing finished appears at the top of the screen, click Next to complete the installation.

9. Optionally, click Generate Installation Script and Properties File to save the installation data in XML files, and then click Done.

   The installer generates two files. The auto.xml file automates future installations and the auto.xml.variables file stores user passwords and other sensitive variables. Use the auto.xml file on multiple systems to easily repeat a Red Hat Decision Manager installation on the same type of server with the same configuration as the original installation. If necessary, update the installpath parameter in the auto.xml file. Enter the following command to perform an installation with the XML file:

   java -jar rhdm-installer-7.8.0.jar <path-to-auto.xml-file>

2. Read the license agreement, enter 1, and press Enter to continue:

   Specify the home directory of one of the following servers:  Red Hat JBoss EAP 7.3 or Red Hat JBoss Web Server 5.3.1

   Copy to Clipboard Toggle word wrap

3. Enter the parent directory of an existing Red Hat JBoss Web Server 5.3.1 installation.

   The installer will verify the location of the installation at the location provided. Enter 1 to confirm and continue.

4. Follow the instructions in the installer to complete the installation.

   Note

   When you create the user name and password, make sure that the specified user name does not conflict with any known title of a role or a group. For example, if there is a role called admin, you should 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 (not including the character &).

   Make a note of the user name and password. You will need them to access Business Central and KIE Server.

5. When the installation has completed, you will see this message:

   Would you like to generate an automatic installation script and properties file?

   Copy to Clipboard Toggle word wrap
6. Enter y to create XML files that contain the installation data, or n to complete the installation. If you enter y, you are prompted to specify a path for the XML files.

7. Enter a path or press the Enter key to accept the suggested path.

   The installer generates two files. The auto.xml file automates future installations and the auto.xml.variables file stores user passwords and other sensitive variables. Use the auto.xml file on multiple systems to easily repeat a Red Hat Decision Manager installation on the same type of server with the same configuration as the original installation. If necessary, update the installpath parameter in the auto.xml file. Enter the following command to perform an installation with the XML file:

   java -jar rhdm-installer-7.8.0.jar <path-to-auto.xml-file>
