| Extreme Transaction Processing - Leveraging Oracle Coherence as a SEDA-based Scalable Event Transaction Processor |
| Taylor Gautier - Principal Client Architect (Grid Dynamics) |
| January 14, 2010 |
Modern telco billing processing systems face huge challenges in the search to move from mostly offline, or batch, processing of billing events to handling huge volumes of events in near-real time. The challenges for an architect of such a system are: how to handle the high throughput processing of near real-time events with low latency while maintaining strict transactional semantics and provide high availability and scalability of the service.
We present our extreme transaction processing solution leveraging Oracle Coherence as an in-memory-data-grid (IMDG) which provides reliable messaging, data storage, and asynchronous write-back to RDBMS. The system follows the staged event driven architecture (SEDA) design pattern providing for a flexible and manageable design that is both highly available and scalable. We discuss lessons learned during performance tuning and profiling plus best practices that are applicable for any Coherence user.

| TopLink Grid - Scaling JPA applications with Coherence |
| Shaun Smith - Principal Product Manager (Oracle) |
| January 14, 2010 |
| JPA, the Java Persistence API, is the Java standard for relational database access. But as is the case for many technologies, scaling JPA applications into large clusters is a challenge. In this session we'll introduce Oracle TopLink's new "TopLink Grid" feature which supports scaling JPA applications through Coherence integration. We'll also introduce the new TopLink Grid enabled "JPA on the Grid" application architecture in which the underlying relational database is replaced by Coherence and all standard database operations, including JPQL query execution, are handled by Coherence. In this session we'll demo how easy it is to leverage Coherence from JPA using TopLink Grid and how to build standards compliant Java EE applications that scale. |
| Coherence Incubator Update & the Processing Pattern Revisited |
| Noah Arliss - Senior Software Engineer (Oracle) |
| January 14, 2010 |
| This presentation will discuss some of the feature themes for the next set of Coherence Incubator releases planned for the end of January. We've done a lot of work since the first release of the Processing Pattern. In this talk we'll look at some of the changes and new features to enable "compute-grid" style development with Coherence. |
| Introduction to Coherence Tools |
| Aleksander Seovic - Founder and Managing Director (S4HC, Inc.) |
| October 1, 2009 |
Oracle Coherence provides many great features out of the box, but it also has a number of extension points. In this session I will provide an overview of Coherence Tools, a collection of Coherence extensions and utilities I created while working on the book and subsequently decided to open source for the benefit of the community.
We will look at things ranging from more powerful value extractors, to different ways to integrate Coherence and Spring, to utilities such as identity generator and cache loader. Best of all, because many of these use Coherence extension points you are already familiar with, you'll be able to use them as soon as you walk out of the meeting. |
| Giving You Persistent Storage "Memory" with Oracle Coherence |
| Patrick Peralta - Senior Software Engineer (Oracle) |
| October 1, 2009 |
| Today's enterprise requires reliable, scalable, and real-time access to mission-critical and constantly changing data. This session explores the benefits that Oracle Coherence, an in-memory data grid, can provide to traditional persistent storage. Oracle Coherence bridges the gap between horizontally scalable, low-latency in-memory access and persistent durable storage. This is the case with a relational database (with or without object-relational mapping), a mainframe, a Web service, or any other persistence mechanism. The presentation explores various caching patterns and techniques to scale both reads and writes in order to meet current and future user demand. |
| Optimizing Your Coherence Network |
| Mark Falco - Consulting Member Technical Staff (Oracle) |
| October 1, 2009 |
| Networking is at the core of Oracle Coherence. All Coherence services sit atop TCMP, a UDP-based cluster protocol. The performance of your Coherence implementation depends on an optimized network infrastructure. This talk, from a Coherence architect, guides you through some of the key factors when tuning your network, and helps you understand how your choices interact with Coherence under the covers. |
| Using Oracle Coherence in a .NET Environment |
| Timur Fanshteyn - FSI Technology Manager |
| June 24, 2009 |
Oracle Coherence can be successfully used in a Microsoft Window and .NET Environment. It can be a excellent media for connecting .Net and Java applications. It can provide .NET applications with a caching solution in front of a database server. It can even be used to provide real-time data to the desktop clients. All with minimum or possible no java coding.
The presentation will go through requirements of setting up Coherence .NET Client. Go through use cases and point out some limitations. We will focus on general data caching, object serialization (through POF), event notifications and LINQ to coherence.
See Timur Fanshteyn's blog for sample files. |
| Coherence*Extend Internals |
| Jason Howes - Consulting Member Technical Staff (Oracle) |
| June 24, 2009 |
Coherence*Extend extends the reach of the core Coherence TCMP cluster to a wider range of consumers, including desktops, remote servers, C++/.Net clients and machines located across WAN connections. Typical uses of Coherence*Extend include providing desktop applications with access to Coherence caches (including support for Near Cache and Continuous Query) and Coherence cluster "bridges" that link together multiple Coherence clusters connected via a high-latency, unreliable WAN.
This talk provides a unique look at the internals of the Extend implementation from one of Coherence's core developers. Starting with the internal Coherence messaging API, Jason will go on to discuss such topics as connection and channel lifecycles, the TCP initiator/acceptor implementation, the CacheService, NamedService, and InvocationService protocols, and the ProxyService implementation. |

| Enhancing and Evolving Coherence Applications with POF |
| Patrick Peralta - Senior Software Engineer (Oracle) |
| April 16, 2009 |
| The Portable Object Format (POF) is the preferred method of serializing objects to a Coherence data grid. It enables heterogeneous C++, .NET, and Java clients to read and write the same objects. POF is a highly efficient serialized object format that also enables objects to evolve in a compatible manner. In this talk, Patrick Peralta will discuss the advantages of POF, and how to use it in your application. |

| WAN Patterns for Coherence |
| Brian Oliver - Global Solutions Architect (Oracle) |
| January 29, 2009 |
| Coherence across a WAN? Push Replication rocks! We've done a lot of work in the past six months to simplify how to use and deploy Coherence Data Grids around the globe. It's always been possible to do these things - Coherence provides some great infrastructure like *Extend to do this - but we've lacked a concrete framework. The Push Replication Pattern is making some serious in-roads to solve some of the challenges faced when designing a globally distributed Data Grid. This presentation will look at the details of some great advantages of this pattern. |

| Scaling Software as a Service (SaaS) with Oracle Coherence |
| Ted Rice - anager of Infrastructure Development (NetSuite) |
| February 19, 2009 |
| In order to create a commercially viable Software as a Service (SaaS) offering, the SaaS system design must be scalable, reliable, and serviceable. A myopic design can limit the the system's ability to add customers, result in a poor user experience, or make growth an expensive proposition. Since its founding in 1998, NetSuite's SaaS platform has grown to handle hundreds of millions of transactions per day. NetSuite uses Coherence in the middle tier, thereby reducing database workload, decreasing application server memory requirements, and simplifying cache design. Ted will describe NetSuite's design, explain the problems NetSuite faced prior to adopting Coherence, and show how Coherence allowed NetSuite to scale core services without sacrificing reliability or performance. |
