Chapter 10. Using the BizTalk Orchestration Designer
by Dilip Hardas
In This Chapter
This chapter describes the usage of the BizTalk Orchestration Designer and builds on the concepts introduced in Chapter 9, “Introducing BizTalk Orchestration.” Chapter 9 outlined four areas of focus, which, to recapitulate, were the business area, implementation area, data flows, and the handling of transaction failures. This chapter is devoted to the implementation of a BizTalk Orchestration schedule using the BizTalk Orchestration Designer. Of the four areas outlined, this chapter covers the second and third areas on implementation and data flows.
The BizTalk Orchestration Designer contains wizards that guide you through creating and configuring ports and message flows. This chapter describes these wizards and the numerous options available when designing XLANG schedules. In the course of describing the designer, we cover important details of how XLANG schedules are put together and operational implications of the choices available to you. The chapter discusses the elements before covering the wizards that configure those elements.
We start by describing the concept of business processes implementation. This is followed by the notion of ports and how these ports are used and bound to the underlying implementation. After describing ports, the messages flowing through the ports are covered. Next, the behavior of messages is described, followed by the options available for the management of state, transactions, and security. At this point of the narrative, there is enough background to cover the options provided by the port implementation wizards. The chapter concludes with the steps required to develop and run an XLANG schedule.
This chapter is a bit longer than Chapter 9; the subject matter covered here deals with many interrelated elements that have complex behaviors. Chapter 11, “XLANG Orchestration Engine,” and Chapter 13, “Advanced BizTalk Orchestration,” cover further Orchestration related topics.
