The Scaling Member feature allows a Liberty clustered server to be managed by a Liberty Scaling Controller server. The Scaling Controller directs the Scaling Member to start and stop based on Scaling Controller policies.
To enable the Scaling Member feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>scalingMember-1.0</feature>
If you are developing a feature that depends on the Scaling Member feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.scalingMember-1.0; type="osgi.subsystem.feature"
