The Orchestration Engine Layer

An orchestration is a flexible, powerful tool for representing an executable business process based on XLANG/s language. At run time, the BizTalk Orchestration Engine executes XLANG/s files that are produced by BizTalk Orchestration Designer. Orchestration Designer is a rich graphical tool for visually designing business processes. It generates XLANG/s files that have an .odx extension and contain additional visualization information in their headers and custom attribute information in their bodies.

The primary functions of the orchestration engine are:

• Persistence
• Hosting the .NET components
• Transactions
• Large message support
• Runtime validation
• Load throttling

Using the tests mapped to the Orchestration Engline layer you can monitor the orchestrations, the BAM interceptor, and the tracking data decode service offered by the Orchestration engine.
