Oracle BPM Suite 11g: Advanced BPMN Topics

Overview of this book

Oracle BPM Suite is a popular and highly capable business process management system with extensive integration capabilities. BPMN, one of the most widely used process modeling notations, includes advanced capabilities for inter-process communication, working of arrays of data, and handling exceptions. However, these very same areas are often poorly understood. This book gives you the knowledge to create professional process models using these advanced features of BPMN."Oracle BPM Suite 11g: Advanced BPMN Topics" is the only book available that provides coverage of advanced BPMN topics for Oracle BPM Suite, helping to fill in the gaps left by the product documentation, and giving you the information that you need to know to use BPMN to its full potential.This book covers the important theory behind inter-process communication, working with arrays and handling exceptions in BPMN, along with detailed, step-by-step practical exercises that demonstrate and consolidate this theoretical knowledge.Throughout the book we'll cover topics including different types of sub-processes, initializing and manipulating arrays, using the multi-instance embedded sub-process, fault propagation and more.With "Oracle BPM Suite 11g: Advanced BPMN Topics" in hand, you'll gain detailed and practical experience in using the advanced features of BPMN to create professional BPMN processes with Oracle BPM.

Using boundary events to implement the cancel message use case


Putting a boundary event on every task can obviously clutter up your process model very quickly, and often we want to treat a group of activities as atomic—we want them all to happen, or none of them. This leads us naturally to the next level of sophistication in the use of boundary events—grouping activities in a sub-process and attaching boundary events to the sub-process.

Let's take a look at this approach now by building an example around the concept of processing an order, but where the possibility of the order being cancelled exists:

  1. Create a new Process in your BoundaryEvents application and name it CancelBoundaryEvent.

    Note

    Let's begin by laying out the process, so we can visualize what we are doing. Then, we will go back and define the data we need. In this example, we are going to use correlation so that we can make sure the cancel message goes to the right process instance.

  2. Move the End node to the side to create some...
