In addition, unicast ports are automatically assigned. Coherence now includes a common cluster port that is used for multicast communication, well known addresses, and extend proxies that are using the name service. ![]() For most use cases, ports and addresses do not need to be explicitly set.Ĭoherence port selection has been simplified to facilitate port management. For more information, see " Support for Generics" in Developing Applications with Oracle Coherence.Ĭluster Port and Address Management – Port and address selection has been changed to simplify cluster management and to allow the sharing of cluster ports and addresses among multiple clusters. In addition, types can be explicitly configured as part of the NamedCache API. The Coherence API has been refactored to support Java Generics. Support for Generics – Java Generics provide compile and runtime type checking together with compile type-inference. For more information, see " Support for Java 8 Features" in Developing Applications with Oracle Coherence. These features provide ease of use and flexibility when performing data grid operations. The features include lambda, streams, and default methods. Support for Java 8 Features – The Coherence API has been updated so that you can use programming features that were introduced in the Java 8 release. For more information, see " Controlling Cipher Suites and Protocol Version Usage" in Securing Oracle Coherence. SSL Protocols and Cipher Suites – An SSL socket provider can be configured to control the use of potentially weak ciphers or specific protocol versions. For more information, see " Programmatically Specifying Local Permissions" in Securing Oracle Coherence. For more information, see " Authorizing Access to Server-Side Operations" in Securing Oracle Coherence.Īdditional JAAS permissions – JAAS permissions protect various parts of the Coherence API using the Java Security Manager. ![]() ![]() For more information, see " Enable Security Audit Logs" in Securing Oracle Coherence.Īccess control authorization – Access control authorization allows applications to define their own authorization logic to limit access to cluster operations. The functionality includes:Īudit logs – Audit logs are used to record user access to cluster operations. Security Enhancements – Coherence includes new security functionality. For more information, see " Replicating Caches Across Clusters" in Administering Oracle Coherence. Cached data is replicated across clusters to provide redundancy, off-site backup, and multiple points of access for application users in different geographical locations. For more information, see " Persisting Caches" in Administering Oracle Coherence.įederated Caching – Federated caching replicates and synchronizes cache data across multiple geographically dispersed clusters. Cached data is persisted so that it can be quickly recovered after a catastrophic failure or after a cluster restart due to planned maintenance. Persistence – Coherence persistence is a set of tools and technologies that manage the persistence and recovery of Coherence distributed caches. This release contains many new features that help reduce complexity, ease configuration, and accelerate time to market of scalable solutions. Oracle Coherence is the industry's leading distributed in-memory data grid product.
