New and Changed Features

New and changed features in Managing Oracle Coherence that are organized by release.

New and Changed Features for 12c (12.2.1.4)

Oracle Coherence 12c (12.2.1.4) includes the following new and changed features for this document.

• REST management, which allows Coherence to be managed using HTTP. See Accessing Management Information Using REST.
• REST based Coherence JVisualVM Plug-In, which allows the VisualVM Coherence plug-in to use REST for management information instead of JMX. See Configure the Coherence-JVisualVM Plug-In to Use REST.
• Metrics Support which provides an endpoint that can be scraped to provide metrics related to the local node. See Using Oracle Coherence Metrics

New and Changed Features for 12c (12.2.1.3)

Oracle Coherence 12c (12.2.1.3) does not contain any new and changed features for this document.

New and Changed Features for 12c (12.2.1.2)

Oracle Coherence 12c (12.2.1.2) does not contain any new and changed features for this document.

New and Changed Features for 12c (12.2.1.1)

Oracle Coherence 12c (12.2.1.1) includes the following new and changed features for this document.

• HTTP Proxy Report, which provides information about HTTP acceptors that are configured on a proxy server. See Understanding the Proxy HTTP Report.

• Attributes on the ConnectionManagerMBean MBean, which provide information for configured proxies. See ConnectionManager MBean.

• HTTP Servers tab, which displays information for HTTP acceptors that are configured on a proxy server. See Overview of Coherence-JVisualVM Plug-in Tabs.

• Force recovery operation, which proceeds with persistence recovery despite the dynamic quorum policy objections. See Table A-16.

• Federated replication attributes, which provides management information for replicateAll operations. See Table A-9.

New and Changed Features for 12c (12.2.1)

Oracle Coherence 12c (12.2.1) includes the following new and changed features for this document.

• Dynamic management mode, which automatically selects the senior-most cluster member as the JMX cluster member. See Using Dynamic Management Mode.

• Java VisualVM plug-in for Coherence, which allows a Coherence cluster to be monitored for real-time analysis and troubleshooting. A new version of the Coherence-JVisualVM plug-in is available and includes new functionality. The functionality includes: reporting node state, displaying near cache statistics, displaying partition statistics, displaying JCache statistics, displaying elastic data statistics, managing cache persistence, and managing federated caching. See Monitor a Coherence Cluster Using the Coherence-JVisualVM Plug-in.

• Federation reports, which provide management information when using federated caching. See Analyzing Report Contents.

• Persistence reports, which provide management information when using cache persistence. See Analyzing Report Contents.

• FederationManagerMBean MBean, TopologyMBean MBean, DestinationMBean MBean, and OriginMBean MBean, which expose management attributes and operations for federated caching. See Oracle Coherence MBeans Reference.

• PersistenceCoordinatorMBean MBean, which exposes management attributes and operations for cache persistence. See PersistenceManager MBean.

• SimpleStrategyMBean MBean, which exposes management attributes and operations when using a simple partition assignment strategy. See SimpleStrategy MBean.
