La deuxième édition du Forum Mondial du libre aura lieu les 1er et 2 octobre 2009, à Paris, avec la tenue de sessions plénières sur les deux jours et d’évènements et conférences associés. Le thème général du Forum sera : “Les Logiciels Libres : au cœur de la relance numérique” (FOSS: At the heart of the Digital Recovery). Le format de l’évènement évolue pour tenir compte des retours d’expérience de l’édition 2008. La première évolution concerne la tenue des plénières sur les deux journées, qui “encadreront” les évènements associés. La seconde portera sur la volonté de privilégier les évènements à fort impact au sein de l’écosystème et au niveau macro économique.
La deuxième édition de l'Open World Forum se déroulera les 1er et 2 octobre 2009 à l'Eurosite George V à Paris. Cet événement regroupe de nombreux acteurs du monde de l'Open Source avec plus de 1200 participants et 20 pays représentés. L'Open World Forum est basé sur le thème : “Les Logiciels Libres : au cœur de la relance numérique”. Le but est de rassembler les communautés, entreprises et politiques pour que le Logiciel Libre soit au coeur de la relance économique.

/dev/websphere: Classifying XTP systems, scale up and scale out transaction processing
A lot of people may think that eXtreme Transaction Processing (XTP) is a new thing. I disagree. XTP systems have been around as long as computers have processed transactions and the definition of what extreme is has been changing with Moores law.
The Green Sheet :: E-Magazine :: XTP: Putting sexy into payments
"Necessity is the mother of invention" is an old adage that describes the high stakes world of extreme transaction processing (XTP). Businesses are confronted with the reality of exponential increase in transaction volume while the dollar amount per transaction is decreasing. So, when a business needs to dramatically increase its capacity to handle electronic transactions without breaking the bank, where does it go? It might go to XTP software vendors like Kabira Technologies, GigaSpaces, Oracle or Appistry Inc.
Testing for performance, scalability, availability, security, manageability and dependability The extreme transaction processing platform (XTPP) is an emerging form of platform middleware technology meant to provide a comprehensive, cohesive and coherent set of functionality to support extreme transaction processing (XTP)-style applications. Now, Gartner defines XTP as "an application style aimed at supporting design, development, deployment, management and maintenance of distributed transaction processing (TP) applications, characterized by exceptionally demanding performance, scalability, availability, security, manageability and dependability requirements."
Extreme Transaction Processing Means Extreme Testing Requirements
Going to Extremes: Extreme Transaction Processing (Part I of II)
Extreme Transaction Processing - What & Why Extreme Transaction Processing (XTP) is an exceptionally demanding form of transaction processing. Transactions of most high-end (more than 10,000 concurrent accesses or 500 transactions per second) or ultra-high-end (more than 100,000 concurrent accesses or 5,000 transactions per second) requirements or more would require this form of processing. Gartner defines XTP as an application style aimed at supporting the design, development, deployment, management and maintenance of distributed TP applications characterized by exceptionally demanding performance, scalability, availability, security, manageability and dependability requirements. Very much like traditional TP systems, XTP applications are aimed at enabling efficient, reliable concurrent and real-time access (read/update) to a shared database by executing application programs commonly referred to as "transactions."
Designing for Extreme Transaction Processing – Memento Pattern « IT Developer World
Designing for Extreme Transaction Processing – Memento Pattern Applications with huge transaction processing requirements or tight response times always result in a careful architecture design. Special care has to be taken on how to partition data in order to be able to better parallelize load. This task can be even trickier if some of the data isn’t suitable for proper partitioning.The Kusnetzky Group LLC is an independent technology industry research firm that focuses on system software, virtualization and cloud computing technology. Dan's opinions are based upon research, personal experiences and actual use of technology. They are not based upon the relationships the company may or may not have with suppliers, end user organizations, the media, consultants or other analysts.

It's becoming more and more clear than conventional tiered architectures have a lot of trouble scaling. Conventional tiering uses a triangular shape. If requests come in from the left then you tend to see multiple tiers moving right until you hit the data source on the right. The tiers are widest in terms of number of processors on the left where the web servers are and then the number drops steadily as we move right closer to the data source. This is why these architectures won't scale indefinitely. People attempt to help scalability by including data source offloading technologies such as caching on the left hand tiers, off loading the data source and allowing it to support more processors in front of it.

Nati Shalom's Blog: Moving to Extreme Transactions Processing using Lean methodology
In one of my recent posts I used a production line analogy to describe the applicability of methodologies like "Lean" taken from production line optimization to transactional systems. As a reminder, here's a good explanation about Lean from Amit Rathore's blog : Ultimately, it focuses on throughput (of whatever is being produced) by taking a strictly system-level view of things. In other words, it doesn’t focus on particular components of the value-stream, but on whether all the components of the chain are working as efficiently as possible, to generate as much overall value as possible.SOA and eXtreme Transaction Processing (XTP) | Weblogic Journal
David Chappell's Blog Across financial services firms we have been seeing a new set of business priorities. There are the "grow the business" priorities that are primarily centered around things like improving customer intimacy and increasing competitive differentiation. here are also ongoing issues of compliance to regulation and risk mitigation while also keeping an eye towards improving cost efficiency. The thing that hasn't changed is that IT is viewed as the enabler to overcome these challenges. Financial institutions are pushing the envelope and require more processing capability, but without requiring exponential increase in hardware costs.Please take a minute to complete our survey and you will be entered to win an exclusive GWC hat or shirt of your choice.
