Coherence clusters consist of multiple managed Coherence server instances that work together to distribute data in-memory to increase application scalability, availability, and performance. A client interacts with the data in a local cache and the distribution and backup of the data is automatically performed across cluster members.

Coherence clusters are different than Converged Application Server clusters. They use different clustering protocols and are configured separately. A Converged Application Server domain can contain a single Coherence cluster. Multiple Converged Application Server clusters can be associated with a Coherence cluster.

For details on configuring and managing Coherence clusters, see Administering Clusters for Oracle WebLogic Server.
