Configuring change events for a business system

You can use the change event functionality to send a change event whenever a business system is changed.

By default, TADDM does not indicate a business system as changed if one of the computers it depends on has changed.

To enable the sending of change events for business systems, complete the following steps:

Open $COLLATION_HOME/etc/propagationserver.xml in an appropriate editor.

In the Computer System section, for the application and business system relationship elements, set the value of the enabled attribute to true.

For example:

<relationship enabled="true" source="sys.ComputerSystem" attribute="groups" 
target="app.Application" targetAttribute="true" 
collectionType="app.FunctionalGroup" radius="1"/>

<relationship enabled="true" source="sys.ComputerSystem" attribute="components" 
target="sys.BusinessSystem" targetAttribute="true"/>

Restart TADDM.
Create a listener for the business system in the change event configuration $COLLATION_HOME/etc/EventConfig.xml.
In the following example, the event recipient is mycompany-itm, and the business system name is MyBiz.
```
<listener object="ITSystem" enabled="true">
	<alert recipient="mycompany-itm"/>
	<attribute name="name" operator="equals">
		<value>MyBiz</value>
	</attribute>
</listener>
```
