Fanning Out Events on the Oracle SOA Suite 11g Event Delivery Network
0On the Oracle Technology Network, architecture section, my article titled “Fanning Out Events on the Oracle SOA Suite 11g Event Delivery Network” has just gone live:
This article describes:
how events can be used in Oracle SOA Suite 11g to have business processes impact each other in a meaningful way with maximum decoupling. Specifically, this article describes a solution for fanning out Event Delivery Network (EDN) events to a more fine-grained level. This allows a single event to influence multiple running instances of a Business Process Execution Language (BPEL) process. The article uses the following Oracle SOA Suite 11g components: BPEL , Mediator ,Event Delivery Network, Spring , Locator API , Composite Sensors
Dear Java/JEE developer – why should you care about ADF?
1Whether you are deciding on the framework to use for your next Java web or mobile project or whether you are contemplating your next career step as a Java EE developer, ADF should be on your short list for consideration. With a new free version, deployment on many application servers including Tomcat, JBoss and GlassFish, extended support in both Eclipse and JDeveloper, and a Java based mobile solution for both iOS and Android – ADF has a lot to offer.
ADF is the Java EE Application Development Framework from Oracle. ADF allows developers to develop rich, enterprise grade Java web and mobile applications in a very productive manner. Many of the generic (plumbing) concerns that need to be addressed for most Java/JEE applications are taken care of by the framework – allowing developers to focus on the business specific functional areas. The initial 80% of the application is created through largely declarative development – 4GL style. The remaining 80% is dealt with in a fairly ordinary coding style, similar to plain Java EE development or to development using other frameworks.
This article discusses the question why any Java/JEE developer should know and care about ADF. It will More >
ADF interaction with business service – an ongoing discussion
0The ADF framework strongly suggests if not dictates a certain application architecture. Through ADF BC (Business Components) – the predominant business service implementation with ADF – applications will typically interact directly with the database, over JDBC Database Connections from a shared connection pool. Developers who create the ADF BC Entity Objects and View Objects will be quite aware of the data model and the database implementation. They will usually write SQL. And the result of their work is substantially coupled with the database. Transactions across multiple data source are very hard to implement in that typical ADF BC scenario because ADF BC talks to a single database and typically controls its own transaction.
When ADF applications are developed in an environment where an enterprise architecture has been laid down, and decoupling is an important objective and service orientation is mandated – then this typical implementation of the business service using ADF BC connecting directly to the database may not be desirable or even allowed.
On one of my projects, we are currently in the situation where we try to determine the guidelines for the implementation of the More >
5 november: Masterclass SOA voor Oracle Database Professionals
0Op maandag 5 november geeft Peter Ebell een één-daagse Masterclass SOA voor Oracle Database Professionals. Deze training wordt gegeven in het kantoor van AMIS in Nieuwegein. Deze Masterclass geeft een overzicht van de belangrijkste concepten binnen SOA. Aan de orde komen Web Services en belangrijke mechanismen zoals XML, XSD, SOAP en WSDL. Tevens wordt de rol van BPEL en de Oracle Service Bus (OSB) beschreven. Vervolgens behandelen we de vele manieren waarop de Oracle SOA Suite – zowel OSB als BPEL – de interactie kan aangaan met de Oracle Database, onder andere door middel van de Database Adapter en de AQ Adapter. Ook de out-of-the-box mogelijkheden van de Oracle Database voor het beschikbaar stellen en aanroepen van web services passeren de revue.
Deze Masterclass is bedoeld voor Oracle Database-Ontwikkelaars en DBA’s die aan de slag zijn, of gewoon meer willen weten, over Service Oriented Architectures (SOA). Dus:
Van de deelnemers wordt verwacht dat zij voorkennis hebben van SQL en PL/SQL. Daarbij is enige jaren ervaring met Oracle Database-Ontwikkeling of –administratie nuttig, maar niet strikt noodzakelijk.
Tijdens deze Masterclass komen onder andere de volgende onderwerpen More >
OOW 2012: BPM is this year’s Fusion Middleware star
0There is no beauty contest to determine which Fusion Middleware product shone the brightest during Oracle Open World. And it is a matter of taste any way. In this case, my taste. So, subjective as it is, my verdict in terms of the MVP (most valuable product) in the category FMW during this year’s OOW conference: BPM!
The main reason for this assessment is the rapid evolution that BPM has shown in the recent passed and is defining for the near future. After having been integrated with JDeveloper and SOA Suite 11g PS3 (April 2010), the Feature Pack 4 release (August 2011) and later the PS5 release (Spring 2012) demonstrated a lot of progress. The roadmap for 2013 looks very promising too.
BPM is one of the best examples of business meeting directly with IT – taking the (existing) business processes and the organization’s strategy and structuring them in a way that allows for clear discussion, optimization and refinement, simulation and even implementation through automated means. With the many (and still expanding) options in Oracle BPM for Design Time at Run Time, the interaction between Business and IT (systems) becomes even more direct. At run time, through simple, (business) More >
