Chapter 6. Downloading and installing the headless Process Automation Manager controller

You can configure Process Server to run in managed or unmanaged mode. 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, use the Execution Server page to create and maintain KIE containers. However, if you do not install Business Central, you can install the headless Process Automation Manager controller and use the REST API or the Process Server Java Client API to interact with it.

Prerequisites

  • A Red Hat JBoss Web Server 5.0.1 or higher server installation is available. The base directory of the Red Hat JBoss Web Server installation is referred to as JWS_HOME.
  • Sufficient user permissions to complete the installation are granted.

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: Process Automation Manager
    • Version: 7.2
  2. Download Red Hat Process Automation Manager 7.2.0 Add Ons (the rhpam-7.2.0-add-ons.zip file).
  3. Unzip the rhpam-7.2.0-add-ons.zip file. The rhpam-7.2-controller-jws.zip file is in the unzipped directory.
  4. Extract the rhpam-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/rhpam-7.2-controller-jws.zip/controller.war directory to the JWS_HOME/tomcat/webapps directory.

    Note

    Ensure the names of the Red Hat Process Automation 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/rhpam-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 Process Server:

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

      CATALINA_OPTS="-Xmx1024m -Dorg.jboss.logging.provider=jdk
       -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"
    • On Windows, add the following content to the setenv.bat file:

      set CATALINA_OPTS=-Xmx1024m -Dorg.jboss.logging.provider=jdk
       -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
  10. In the JWS_HOME/tomcat/bin directory of the instance running the headless Process Automation 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 Process Automation Manager controller, enter one of the following commands in the JWS_HOME/tomcat/bin directory:

    • On Linux or UNIX-based systems:

      $ ./startup.sh
    • On Windows:

      startup.bat
  12. After a few minutes, review the JWS_HOME/tomcat/logs directory and correct any errors.
  13. To verify that the headless Process Automation 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 Process Server instance.

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

Alternatively, you can use the Process Server Java API Client to access the headless Process Automation Manager controller.
