Red Hat Training

A Red Hat training course is available for Red Hat Process Automation Manager

Chapter 4. Using the Red Hat Process Automation Manager installer

This section describes how to install Process Server and the headless Process Automation Manager controller using the installer JAR file. The JAR file is an executable file that installs Red Hat Process Automation Manager in an existing Red Hat JBoss EAP 7.2 server installation. You can run the installer in interactive or command line interface (CLI) mode.

Note

The Red Hat Process Automation Manager JAR file installer does not support the Red Hat JBoss EAP distribution installed by yum or RPM Package Manager. If you want to install Red Hat Process Automation Manager in this type of Red Hat JBoss EAP installation, download the Red Hat Process Automation Manager 7.2 Deployable for Red Hat JBoss EAP 7.2 file and follow the steps in Chapter 5, Installing Red Hat Process Automation Manager from ZIP files.

Note

Because IBM JDK cannot use keystores generated on other JDKs, you cannot install Red Hat Process Automation Manager into an existing Red Hat JBoss EAP installation running on IBM JDK with a keystore generated on another JDK.

Next steps:

Follow the instructions in one of the following sections:

4.1. Using the installer in interactive mode

The installer for Red Hat Process Automation Manager is an executable JAR file. You can use it to install Red Hat Process Automation Manager in an existing Red Hat JBoss EAP 7.2 server installation.

Note

For security reasons, you should run the installer as a non-root user.

Prerequisites

  • A backed-up Red Hat JBoss EAP 7.2 or higher server installation is available.
  • Sufficient user permissions to complete the installation are granted.

  • The JAR binary is included in $PATH environment variable. On Red Hat Enterprise Linux, it is included in the java-$JAVA_VERSION-openjdk-devel package.

    Note

    Red Hat Process Automation Manager is designed to work with UTF-8 encoding. If a different encoding system is used by the underlying JVM, unexpected errors might occur. To ensure UTF-8 is used by the JVM, use the "-Dfile.encoding=UTF-8" system property.

Procedure

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

    java -jar rhpam-installer-7.2.0.jar
    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
rhpam-installer-7.2.0.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
rhpam-installer-7.2.0.jar

    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 EAP 7.2 server home where you want to install Red Hat Process Automation Manager and click Next.

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

    Note

    You can install Business Central and Process Server on the same server. However, you should install Business Central and Process Server on different servers in production environments. To do this, run the installer twice.

  5. Create a user and click Next. By default, the new user is given the admin, kie-server, and rest-all roles. To select another role, deselect admin. For more information, see Chapter 2, Roles and users.

    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 Process 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. On the Configure Runtime Environment page, choose whether to perform the default installation or perform an advanced configuration.

    If you choose Perform advanced configuration, you can choose to configure database settings or customize certain Process Server options.

  9. If you selected Customize database settings, on the JDBC Drive Configuration page specify a data source JDBC driver vendor, select one or more Driver JAR files, and click Next.

    A data source is an object that enables a Java Database Connectivity (JDBC) client, such as an application server, to establish a connection with a database. Applications look up the data source on the Java Naming and Directory Interface (JNDI) tree or in the local application context and request a database connection to retrieve data. You must configure data sources for Process Server to ensure proper data exchange between the servers and the designated database.

  10. If you selected Customize Process Server settings, change any of the following, if desired:

    • Change the name of the Process Server property.
    • Change the URL of the headless Process Automation Manager controller.
    • Deselect any Process Server server options.
  11. Click Next to configure the runtime environment.
  12. When Processing finished appears at the top of the screen, click Next to complete the installation.

  13. If desired, click Generate Installation Script and Properties File to save the installation data in an XML file, and then click Done. You can use this file to automatically install Red Hat Process Automation Manager on the same type of server. Note that you must change the installpath parameter in the XML file to specify the path of the new server that you want to install Red Hat Process Automation Manager on. Enter the following command to perform an installation with the XML file: 

    java -jar rhpam-installer-7.2.0.jar <path-to-file>

You have successfully installed Red Hat Process Automation Manager using the installer. If you installed only Business Central, repeat these steps to install Process Server on a separate server.

4.2. Using the installer in CLI mode

You can run the Red Hat Process Automation Manager installer through the command-line interface (CLI).

Note

For security reasons, you should run the installer as a non-root user.

Prerequisites

  • A backed-up Red Hat JBoss EAP 7.2 or higher server installation is available.
  • Sufficient user permissions to complete the installation are granted.

  • The JAR binary is included in the $PATH environment variable. On Red Hat Enterprise Linux, it is included in the java-$JAVA_VERSION-openjdk-devel package.

    Note

    Red Hat Process Automation Manager is designed to work with UTF-8 encoding. If a different encoding system is used by the underlying JVM, unexpected errors might occur. To ensure UTF-8 is used by the JVM, use the "-Dfile.encoding=UTF-8" system property.

Procedure

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

    java -jar rhpam-installer-7.2.0.jar -console

    The command-line interactive process will start and display the End-User License Agreement. 

    press 1 to continue, 2 to quit, 3 to redisplay.

  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 7.2

  3. Enter the parent directory of an existing Red Hat JBoss EAP 7.2 installation.

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

    Note

    You can install Business Central and Process Server on the same server. However, you should install Business Central and Process Server on different servers in production environments.

  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 Process Server.

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

    Would you like to generate an automatic installation script and properties file?
  6. Enter y to create an XML file that contains the installation data, or n to complete the installation. If you enter y, you are prompted to specify a path for the XML file.
  7. Enter a path or press the Enter key to accept the suggested path.
  8. If you installed only Business Central, repeat these steps to install Process Server on a separate server.

4.3. Using the installer to configure Process Server with the Process Automation Manager controller

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

The Process Automation 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 Process Automation Manager controller.

You can use the installer in interactive or CLI mode to install Business Central and Process Server, and then configure Process Server with the Process Automation Manager controller.

Note

If you do not install Business Central, see Chapter 9, Installing and running the headless Process Automation Manager controller for information about using the headless Process Automation Manager controller.

Prerequisites

  • Two computers with backed-up Red Hat JBoss EAP 7.2 or higher server installations are available.
  • Sufficient user permissions to complete the installation are granted.

Procedure

  1. On the first computer, run the installer in interactive mode or CLI mode. See one of the following sections for more information:

  2. On the Component Selection page, clear the Process Server box.
  3. Complete the Business Central installation.
  4. On the second computer, run the installer in interactive mode or CLI mode.
