Overview of this book

<p>Completing the Oracle SOA Infrastructure Implementation Certification develops your conceptual and real-world understanding of the primary components of the Oracle SOA Suite, including BPEL process engine and Oracle Service Bus and will allow you to become familiar with Service Oriented Architecture concepts.<br /><br /><br />This definitive certification guide provides a disciplined approach to be adopted for successfully clearing the 1Z0-451 Oracle SOA Foundation Practitioner exam to attain the Oracle SOA Infrastructure Implementation Certification.<br /><br />The book starts with essential SOA concepts and then dives into building of composite applications. You will then learn how to work with technology and application adapters. Next, you will learn orchestrating Services with BPEL and advanced BPEL concepts. Midway through the book you will learn about Mediator components and Human Workflows. The book will then cover Oracle Business Rules and securing services and composite applications. Towards the end of the book, you will learn how to monitor and manage SOA Deployment. The book concludes&nbsp; with a post assessment exam that will give you a feel for the actual SOA Foundation Practitioner exam, and a must-have developer reference that covers important SOA concepts.</p>

Parallel flow and conditional branching


Parallel flows can be achieved using the Flow and FlowN (ForEach in BPEL 2.0) activities. Flow activity will help to execute the BPEL activities in parallel. This will reduce the process time if independent activities are performed as a part of the same business process. Flow activity is typically used in scenarios where results from invoking multiple asynchronous processes are independent to each other. Flow activity will determine the number of flow arms during design time. Flow allows calling or executing different business logic simultaneously, but the order of execution is not guaranteed. FlowN allows true parallelism by calling upon the same set of business logic on different sets of data. The ForEach construct, introduced in BPEL 2.0, also allows the process to dynamically pick up partners and perform operations similar to FlowN.
