Description:
A higher level control and coordination mechanism is required for exception handling in workflow systems. This paper describes such a framework based on events, states, and a new kind of process called a meta workflow. Meta workflows have five kinds of meta activities and facilitate control over base workflows. We describe the framework and illustrate it with examples to show its features. The paper gives an architecture for incorporating it into existing workflows and also provides a formal semantics of execution. This framework can be used in Web services, supply chains, and inter-organizational applications where coordination requirements are complex, and flexible and adaptable workflows are needed. It is also useful for handling not just failure recovery but also various kinds of special situations, which arise frequently in web-based applications.

BPEL-Tools im Vergleich: Open Source-BPEL-Tools und Oracle SOA Suite

Product Description
Schon seit einiger Zeit sind die Probleme der Softwareentwicklung wie zunehmende Komplexität und Heterogenität sowie fehlende Flexibilität bekannt. Einen viel versprechenden Ansatz in Bezug auf die beschriebenen Probleme stellt die Service-orientierte Architektur (SOA) dar. Auch IT-Trends wie das steigende Interesse an Prozessorientierung und Schwerpunkverlagerung von Anwendungsprogrammierung zu Anwendungsintegration fließen hier ein. Eine aussichtsreiche Lösung im Kontext prozessorientierter Softwareentwicklung basierend auf einer SOA ist die Business Process Execution Language (BPEL). Anatoliy Babiychuk erläutert in seinem Buch ausführlich die Grundlagen des Workflow-Managements und der SOA. Nachfolgend werden die BPEL-Konzepte vorgestellt. Auch dem zunehmenden Interesse an Open Source wird in diesem Buch Rechnung getragen. Eine Übersicht über die vorhandenen Open Source-Tools und ein Vergleich des am weitesten entwickelten Open Source-BPEL-Tools mit einem kommerziellen Werkzeug (Oracle Soa Suite) bilden die Schwerpunkte dieser Arbeit. Abschließend werden auch Migrationsmöglichkeiten von BPEL-Prozessen analysiert. Das Buch richtet sich an IT-Experten und interessierte Studenten.

BPEL 100 Success Secrets – Business Process Execution Language for Web Services- THE XML-based language for the formal specification of business processes, … protocols and SOA based integration

Product Description
Excellent introduction to BPEL – the business process execution language. A number of Web services orchestration / process tools are based on BPEL but hide the language behind a drag-and-drop GUI. To effectively use these tools, though, you have to understand the concepts that make up BPEL – scopes, partner links, correlation sets etc. This book likely provides the best introduction to these concepts. Examples are given in raw BPEL as well as using Oracle BPEL Manager and Microsoft BizTalk. There is coverage of advanced topics, such as correlation and convoys, a great introduction to BPEL best practices. In summary, if you are interested specifically in BPEL, this is likely the book you want to get.
