Chapter 8. Configuring KIE Server to connect to Business Central

Warning

This section provides a sample setup that you can use for testing purposes. Some of the values are unsuitable for a production environment, and are marked as such.

If a KIE Server is not configured in your Red Hat Decision Manager environment, or if you require additional KIE Servers in your Red Hat Decision Manager environment, you must configure a KIE Server to connect to Business Central.

Note

If you are deploying KIE Server on Red Hat OpenShift Container Platform, see the Deploying a Red Hat Decision Manager environment on Red Hat OpenShift Container Platform 4 using Operators document for instructions about configuring it to connect to Business Central.

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

Note

Make the changes described in this section if KIE Server is managed by Business Central and you have installed Red Hat Decision Manager from the ZIP files. If you have installed Business Central, you can use the headless Decision Manager controller to manage KIE Server, as described in Chapter 9, Installing and running the headless Decision Manager controller.

Prerequisites

Business Central and KIE Server are installed in the base directory of the Red Hat JBoss EAP installation (EAP_HOME).

Note

You must install Business Central and KIE Server on different servers in production environments. In this sample situation, we use only one user named controllerUser, containing both rest-all and the kie-server roles. However, if you install KIE Server and Business Central on the same server, for example in a development environment, make the changes in the shared standalone-full.xml file as described in this section.

Users with the following roles exist:
- In Business Central, a user with the role rest-all
- On KIE Server, a user with the role kie-server

Procedure

In your Red Hat Decision Manager installation directory, navigate to the standalone-full.xml file. For example, if you use a Red Hat JBoss EAP installation for Red Hat Decision Manager, go to $EAP_HOME/standalone/configuration/standalone-full.xml.

Open the standalone-full.xml file and under the <system-properties> tag, set the following JVM properties:

Table 8.1. JVM Properties for the managed KIE Server instance
Property	Value	Note
`org.kie.server.id`	`default-kie-server`	The KIE Server ID.
`org.kie.server.controller`	`http://localhost:8080/decision-central/rest/controller`	The location of Business Central. The URL for connecting to the API of Business Central.
`org.kie.server.controller.user`	`controllerUser`	The user name with the role `rest-all` who can log in to the Business Central.
`org.kie.server.controller.pwd`	`controllerUser1234;`	The password of the user who can log in to the Business Central.
`org.kie.server.location`	`http://localhost:8080/kie-server/services/rest/server`	The location of KIE Server. The URL for connecting to the API of KIE Server.

Table 8.2. JVM Properties for the Business Central instance
Property	Value	Note
`org.kie.server.user`	`controllerUser`	The user name with the role `kie-server`.
`org.kie.server.pwd`	`controllerUser1234;`	The password of the user.

The following example shows how to configure a KIE Server instance:

<property name="org.kie.server.id" value="default-kie-server"/>
<property name="org.kie.server.controller" value="http://localhost:8080/decision-central/rest/controller"/>
<property name="org.kie.server.controller.user" value="controllerUser"/>
<property name="org.kie.server.controller.pwd" value="controllerUser1234;"/>
<property name="org.kie.server.location" value="http://localhost:8080/kie-server/services/rest/server"/>

The following example shows how to configure a for Business Central instance:

<property name="org.kie.server.user" value="controllerUser"/>
<property name="org.kie.server.pwd" value="controllerUser1234;"/>

To verify that KIE Server starts successfully, send a GET request to http://SERVER:PORT/kie-server/services/rest/server/ when KIE Server is running. For more information about running Red Hat Decision Manager on KIE Server, see Running Red Hat Decision Manager.

After successful authentication, you receive an XML response similar to the following example:

<response type="SUCCESS" msg="Kie Server info">

</response>

Verify successful registration:
1. Log in to Business Central.
2. Click Menu Deploy Execution Servers.
  If registration is successful, you will see the registered server ID.
