Discovery of the Coherence cluster

A Coherence cluster usually has a large number of nodes that may run on multiple hosts. As we discussed earlier, a node could either be a storage, proxy, or management node and each node is nothing but a JVM process. For example, a Coherence node may have 16 nodes, where 14 may be storage nodes and one may be a management node and another a proxy node. The management node hosts a JMX server, and Oracle Enterprise Manager depends on the management node for discovering and monitoring the Coherence cluster. The Oracle Management Agent talks to the management node for collecting metrics, propagating runtime configuration changes, and so on.

Enterprise Manager discovers the entire cluster in a single step and requires a single agent to monitor the entire cluster.

Note

The agent can either be local or remote where management node is running. The agent box should be able to communicate with the host running the management node.
