In this topology, the application is clustered using the clustering capabilities of the Java EE application server. The Management Agent communicates with the management EJB on the managing node of the application server; that is, the deployment manager for WebSphere® Application Server Network Deployment Edition.
The Management Agent uses the management EJB to locate particular deployments and instances of the application in the clustered environment or, more precisely, the management beans that control these deployments and instances. This is required so that the Management Agent can inform the application about configuration changes.
In this configuration, the Management Agent and Management Console are located on the same computer as the managing node of the application server, but not necessarily the same computer as the application itself.
There are no additional administrative actions to be taken whenever the structure of the cluster and the mapping of the application to the cluster changes. The Management Agent automatically discovers the topology of the cluster through the management EJB.
