6.7. Setting System Properties

Servers and particularly subsystems, which are integrated services, can have additional configuration properties added as system properties. The system property is a simple attribute-value pair, and it can be anything. The system properties which are available depend on the resource being edited.
When editing profiles and subsystems, extensions, server groups, and other domain components, system properties are added to the component's entry in the domain.xml file. When editing a host controller or a managed server, the properties are added to the server's entry in the host.xml file.

Note

System properties, as with other configuration elements in the domain, work in a cascade. If a system property is set on a server group, it applies to all members of the group. If it is set on a managed server, it applies only to that server.
Be sure to edit the entry at the appropriate level in the domain so that the configuration is applied appropriately.
System properties set default configuration; these can be overridden with the start script in the -D or -P arguments.

Note

If drift monitoring is configured, then adding or editing system properties could trigger a drift alert. See Section 6.12, “Controlling Configuration Drift”.
Check the project documentation for information on available system properties:
To add system properties to the configuration:
  1. Click the Inventory tab in the top menu.
  2. Select Servers - Top Level Imports in the Resources menu table on the left. Select the JBoss EAP 6 server.
  3. In the inventory tree, select the top resource entry for the server.
  4. Open the Configuration tab.
  5. Expand the Properties section.
  6. Click the green plus (+) icon at the bottom of the Paths list.
  7. Fill in the new property information.
    • The system property name.
    • The value of the property.
    • If the property should be loaded immediately to the running JVM or if it should be loaded when the JVM is started. The default is to load it immediately.
  8. Click OK.
