Chapter 39. Downloading and installing the headless Process Automation Manager controller
You can configure KIE Server to run in managed or unmanaged mode. If KIE Server is unmanaged, you must manually create and maintain KIE containers (deployment units). If KIE Server is managed, the Process Automation Manager controller manages the KIE 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 KIE Server Java Client API to interact with it.
Prerequisites
-
The Red Hat Process Automation Manager 7.13.5 Add Ons (
rhpam-7.13.5-add-ons.zip
) file has been downloaded, as described in Chapter 34, Downloading the Red Hat Process Automation Manager installation files. -
A Red Hat JBoss Web Server 5.5.1 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
-
Extract the
rhpam-7.13.5-add-ons.zip
file. Therhpam-7.13.5-controller-jws.zip
file is in the extracted directory. -
Extract the
rhpam-7.13.5-controller-jws.zip
archive to a temporary directory. In the following examples this directory is calledTEMP_DIR
. Copy the
TEMP_DIR/rhpam-7.13.5-controller-jws.zip/controller.war
directory to theJWS_HOME/tomcat/webapps
directory.NoteEnsure the names of the Red Hat Process Automation Manager deployments you copy do not conflict with your existing deployments in the Red Hat JBoss Web Server instance.
-
Remove the
.war
extensions from thecontroller.war
folder. -
Copy the contents of the
TEMP_DIR/rhpam-7.13.5-controller-jws/SecurityPolicy/
directory toJWS_HOME/bin
- When prompted to overwrite files, select Yes.
Add the
kie-server
role and user to theJWS_HOME/tomcat/conf/tomcat-users.xml
file. In the following example,<USER_NAME>
and<PASSWORD>
are the user name and password of your choice:<role rolename="kie-server"/> <user username="<USER_NAME>" password="<PASSWORD>" roles="kie-server"/>
Complete one of the following tasks in the
JWS_HOME/tomcat/bin
directory of the instance running KIE 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
In the preceding examples, replace the following variables:
-
Replace
<CONTROLLER_USER>
and<CONTROLLER_PWD>
with the user name and password for thekie-server
role that you defined earlier in this procedure. -
Replace
<KIE_SERVER_ID>
with a unique identifier. -
Replace
<CONTROLLER_HOST>:<CONTROLLER_PORT>
with the IP address (host and port) of the controller. If you use the same server for KIE Server and the controller,<CONTROLLER_HOST>:<CONTROLLER_PORT>
islocalhost:8080
.
In the
JWS_HOME/tomcat/bin
directory of the instance running the headless Process Automation Manager controller, create a readablesetenv.sh
file with the following content, where<USERNAME>
is the KIE Server user and<USER_PWD>
is the password for that user:CATALINA_OPTS="-Dorg.kie.server.user=<USERNAME> -Dorg.kie.server.pwd=<USER_PWD>"
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
-
After a few minutes, review the
JWS_HOME/tomcat/logs
directory and correct any errors. -
To verify that the headless Process Automation Manager controller is working correctly, enter
http://<CONTROLLER_HOST>:<CONTROLLER_PORT>/controller/rest/controller/management/servers
in a web browser. If you use the same server for KIE Server and the controller,<CONTROLLER_HOST>:<CONTROLLER_PORT>
islocalhost:8080
. -
Enter the user name and password stored in the
tomcat-users.xml
file.
