Application Description
Tangosol
Coherence is a JCache-compliant in-memory caching and data
management solution for clustered J2EE applications and application
servers. Coherence makes sharing and managing data in a cluster as
simple as on a single server. It accomplishes this by coordinating
updates to the data using cluster-wide concurrency control,
replicating and distributing data modifications across the cluster
using the highest performing clustered protocol available, and
delivering notifications of data modifications to any servers that
request them.
Developers can easily take advantage of Coherence features using
the standard Java collections API to access and modify data, and
use the standard JavaBean event model to receive data change
notifications. Functionality such as HTTP session replication is
available out-of-the-box for applications deployed to Servlet
2.3-compliant application servers, such as Java System Application
Server (formerly Sun ONE Application Server).
Integration with Java System Application Server
Java System Application Server and applications utilizing Java
System Application Server use Coherence for clustering, caching and
in-memory data management. Coherence enables reliable, scalable
access to common data at memory speeds from multiple Sun Java
System (formerly Sun ONE) JVM instances. Coherence enables Java
System Application Servers to be effortlessly clustered together
and share any type of application and state data through Coherence
caches at memory speeds. In addition to enabling applications to
keep frequently used and shared data in memory reducing database
load and improving application scalability, Coherence also
preserves data it manages by providing transparent fail-over and
failback so applications can continue running without interruption
even as servers or networks experience failures.
Benefit to customers
Using Tangosol Coherence and Java System Application Server
together customers can create and deploy clustered J2EE
applications that exhibit very predictable scalable performance
when the deployed in a single-server installation or up to a
cluster of hundreds of Java System Application Servers. Using HTTP
Session replication, session state can be easily shared among Java
System Application Server instances. All the data managed by
Coherence is reliably preserved and available to the application
instances for uninterrupted application operation.
