By automatically and dynamically partitioning data in memory across multiple servers, Oracle Coherence enables continuous data availability and transactional integrity, even in the event of a server failure. As a shared infrastructure, Oracle Coherence combines data locality with local processing power to perform real-time data analysis, in-memory grid computations, and parallel transaction and event processing.
Note:
If you are logged into a domain partition, navigate from the Domain Partition menu.
This chapter includes the following sections:
This section describes how to create managed Oracle Coherence clusters and how to add standalone Oracle Coherence clusters. Managed Oracle Coherence clusters are comprised of managed Oracle Coherence servers that are part of a WebLogic Server domain. Standalone Oracle Coherence clusters are comprised of Oracle Coherence servers that are not part of a WebLogic Server domain.
This section includes the following tasks:
To create a new managed Oracle Coherence cluster:
On the Properties page, define the general cluster properties for your new managed Oracle Coherence cluster:
Name: enter a unique name for your cluster.
Clustering Mode: if you selected Configure within WebLogic Server, then select either unicast or multicast for the cluster network transmission.
Cluster Listen Port: if you selected Configure within WebLogic Server, then enter the cluster listen port. Oracle Coherence cluster members use this port to discover and join, or create, the cluster. The default port is 7574.
Multicast Listen Address: if you selected Configure within WebLogic Server and you are using multicast, enter an IP address for the cluster multicast listener.
Custom Configuration File Name: if you selected Use a Custom Configuration File, enter the location of a Oracle Coherence cluster configuration file that defines the cluster properties. You can click Browse to navigate to the file location.
For more information about these fields, see Configuration Options.
On the Members page, you can specify the WebLogic Server clusters or specific managed servers to associate with this managed Oracle Coherence cluster.
For more information, see Configuration Options.
On the Review page, review the configuration for your new managed Oracle Coherence cluster.
