Coherence 12cR2 Offers Major New Innovations by Craig Blitz


clip_image001We are very happy to announce major new innovations with the release of Oracle Coherence 12.2.1 This release is one of the largest we have done and delivers several major features aimed at both developers and operations that improve developer productivity, support infrastructure consolidation, provide better security, and simplify multi-datacenter solutions. We are also announcing a new licensing option for low-cost deployment of small-to-medium sized deployments.

New Features

Coherence 12.2.1 is packed with major new features and capabilities:

  • The new Persistence feature enables Coherence to be a system-of-record and improves time-to-recovery from planned or unplanned, partial or total, cluster outage. Persistence can be configured to work in an on-line mode persisting changes as they are made to the cluster, or to take a snapshot of a data grid. Local disk configuration maximizes scalability, while network-attached storage maximizes availability.   Both data and metadata (indexes, listeners, expiry, locks, etc.) are stored, and recovery is completely automatic.
  • Federated Caching provides support for Active-Active, Active-Passive, Hub and Spoke, and custom multi-datacenter topologies. Implemented at the lowest level of Coherence, Federated Caching takes advantage of Message Bus, Elastic Data, and our new Persistence feature to improve scalability, durability, latency, and configurability of data replication over prior solutions. 
  • Coherence Multitenancy allows WebLogic Server Multitenant applications to share a cluster across a set of tenants and applications, consolidating infrastructure requirements. Multitenancy provides tenant-specific caches as well as shared caches for hosting reference data.  It is fully integrated with Oracle Traffic Director, WebLogic Server, and the Oracle Database to provide an end-to-end multitenant solution.
  • One of our most exciting new features is the integration we have done with Java 8 to provide Distributed Lambdas and Streams. We now provide the ability to execute Lambdas and Streams remotely, using standard Java 8, distributed across cluster members, without the need to deploy code on cluster servers. This provides the ability to do distributed, parallelized stream-based functional programming.  By reducing the need to deploy classes to servers, we have also greatly simplified application upgrade.
  • New Security Features include the ability to do fine-grained Authorization and Auditing of all cache access and updates.   We have also improved our SSL support. Read the complete article here.
