Tangosol has released Coherence 1.2.1, its pure Java Distributed Cache product for J2EE AppServers. The new version adds configurable redundancy of data and configurable compression of its cluster communication protocol. Check out Coherence. Press Release -------------------------- Somerville Mass -- September 19, 2002 -- Tangosol, Inc. announces immediate availability of Coherence 1.2.1, its enterprise-class clustered data management and caching product. With new support for data redundancy managed by its Distributed Cache service, Coherence is the only Java solution that provides support for massive data caching and management in a clustered J2EE application. By splitting up a massive cache of data among the servers in a cluster, Coherence allows high-scale enterprise applications to increase their effective cache potential through cost-effective horizontal scale. By automatically balancing data management across the cluster, and ensuring that each piece of data is stored redundantly, Coherence-enabled applications can survive server failure, immediately failing over data management responsibilities to available nodes. By leveraging an asynchronous peer-to-peer based clustering protocol, Coherence scales far higher than competing solutions and eliminates all single points of failure. Also new in release 1.2.1 is improved WAN clustering support through configurable compression of the cluster communication protocol. Coherence is the only clustering software designed to work effectively and efficiently on high-latency low-bandwidth networks, and now it can efficiently communicate higher volumes of data over low-bandwidth networks. Coherence 1.2.1 provides a new filter API for snapping in network filters, such as encryption filters and compression filters. Coherence customers now have the widest variety of options for managing the security and bandwidth utilization of their clustered applications. Additionally, Coherence provides: - Coherence HTTP Session Clustering replicates HTTP sessions in-memory for BEA WebLogic 7, IBM WebSphere 4, Apache Tomcat 4, and all Servlet 2.3 compliant application servers with support for both sticky and stateless load-balancing. - Coherence is now certified by IBM as a "Powered by WebSphere" application (new!) - Coherence Clustered Data Stores provide coherent replicated and distributed (network-partitioned) data storage in a cluster using the same standard Java API. - Coherence Size-Limited Cache provides the only clustered size-limited cache implementation with automatic timed expiration of data, scheduled cache flushes and a combination Most Recently Used + Most Frequently Used algorithm. - Coherence Network Fault Tolerance gracefully handles physical network interruption. - Coherence Death Detection automatically and quickly fails over dead and unresponsive servers.
