In 10.1.x.x, when a DB Control was deployed on a RAC cluster with n nodes, a dbconsole was started on each node of the cluster. Each agent on each node reported to each dbconsole management service on the same node. In 10.2.x.x, to improve performance and reduce the workload on the RAC database/instances,when a DB Control is first deployed on a RAC cluster with n nodes, a dbconsole is started only on the node from which the DB Control is deployed. Each agent on each node reports to that same unique dbconsole management service. It is however possible to later reconfigure the DB Control to have more than one dbconsole started and to have agents reporting to several dbconsole.
