Oracle Announces Latest Version of Coherence Data Grid
Building on its commitment to deliver a foundation for a modern application infrastructure, Oracle announced the general availability of Oracle Coherence 3.3, an in-memory data grid and the latest hot-pluggable component of Oracle Fusion Middleware. To address growing Extreme Transaction Processing (XTP) requirements, this release features enhanced performance, quality-of-service and clustering capabilities, tighter integration with Oracle Fusion Middleware, and support for Microsoft's .NET Framework. Oracle Coherence 3.3 is now available in three editions -- Standard, Enterprise and Grid.
Designed to meet organizations' need to predictably scale
mission-critical applications by helping to provide fast and reliable
access to frequently used data, Oracle Coherence 3.3 enables customers
to push data closer to the application for faster access and greater
resource utilization. By automatically and dynamically partitioning
data in memory across multiple servers, Oracle Coherence enables
continuous data availability and transactional integrity, even in the
event of a server failure. As a shared infrastructure, the offering
combines data locality with local processing power to perform real-time
data analysis, in-memory grid computations, and parallel transaction
and event processing.
Key Enhancements Extend Extreme Transaction Processing
To satisfy the growing demand for XTP capabilities, Oracle rapidly tightened the integration of Oracle Coherence with components of Oracle Fusion Middleware and focused on four specific enhancements related to XTP and high-performance applications:
- Availability -- The introduction of Deterministic Request Execution features.
- Clustering -- Delivery of self-tuning communication capabilities, including both high-performance packet bundling and dynamic flow control.
- Performance -- Enhanced multi-core support for the latest commodity server hardware.
- Platform
Support -- Expanded to include Java SE version 6, and a new revision of
Oracle Coherence for the Microsoft .NET Platform.
Additionally, the release enables tight integration with a number of
Oracle Fusion Middleware products, including Oracle Application Server
and Oracle TopLink.
"As a leading provider of financial electronic commerce, our IT
infrastructure supports electronic billing and payment for more than
2,000 financial services sites -- a classic extreme transaction
processing environment," said Mark Prout, vice president of engineering
services at CheckFree. "We turned to Oracle Coherence when we realized
the demands from mainstream adoption of paying bills online would
ultimately outgrow the capacity of our home grown caching solution. The
enhanced release of Oracle Coherence provides us the scalability we
need to continue to grow our business."
Designed to support Java and J2EE applications, developers can
easily take advantage of Oracle 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 management is available
out-of-the-box for applications.
"As elements of a modern application infrastructure such as
service-oriented architecture, Web 2.0 and event-driven architecture
push the
scalability, reliability and performance envelope, organizations are
increasingly relying on middleware to distribute application processing
and more efficiently utilize resources," said Cameron Purdy, vice
president of development at Oracle. "Combining the in-memory data grid
infrastructure of Oracle Coherence with Oracle Fusion Middleware, we
now offer customers a comprehensive solution to address their evolving
XTP requirements."
"Advanced service-oriented architecture, multichannel, Internet-enabled business models will push transactional requirements to the extreme," said Gartner Vice President and Distinguished Analyst Massimo Pezzini in an August 2006 report. "Extreme TP will dramatically affect technologies, vendor strategies and user architectures."
