Summary

Coherence cluster is a very popular technology that provides distributed caching services. In this chapter, we learnt how to discover a Coherence cluster from Enterprise Manager. You can now monitor a Coherence cluster either by using a local or remote management agent. Bulk Operation Mbean is recommended for better performance in metrics collection and aggregation when you have a large number of Coherence nodes. Enterprise Manager monitors Coherence cluster by talking to a single management node. We can use Enterprise Manager to monitor the health and performance of Coherence cluster and learned how to monitor and diagnose issues in different entities such as nodes, caches, services, and so on. We also learned configuration comparison and rolling out real-time configuration changes. We can use Coherence node provisioning feature to create a new Coherence cluster or add new nodes to an existing Coherence cluster.

Today heterogeneous systems are very common and you would expect that...
