1 Module 8: Creating a BizTalk Orchestration

2 Overview Lesson 1: Introduction to BizTalk Orchestration Lesson 2: Building an Orchestration Lesson 3: Monitoring Orchestrations

3 Lesson 1: Introduction to BizTalk Orchestration Modeling a Business Process What Is an Orchestration? How the BizTalk Orchestration Engine Works Orchestrating a Business Process Stages of Orchestration Development Importing and Exporting BPEL

4 Modeling a Business Process Buyer Organization Vendor Organization Procurement App Finance App UserPO Approver Invoice Approver Purchase request PO request approval Purchase order Purchase order acknowledgement Shipping order Invoice Payment Invoice approval Invoice request approval PO approval Request acknowledgement Vendor Warehouse

9 Test the orchestration 8 8 Configure bindings, enlist and start the orchestration 7 7 Build and deploy the orchestration 6 6 Assign or transform data 5 5 Add orchestration shapes 4 4 Define send and receive ports 3 3 Define orchestration variables and types 2 2 Define schemas 1 1 Stages of Orchestration Development

10 Importing BPEL Use to create an orchestration from BPEL Select BPEL import project type Run BPEL Import Wizard to select BPEL, WSDL, and XSD files Use to create an orchestration from BPEL Select BPEL import project type Run BPEL Import Wizard to select BPEL, WSDL, and XSD files Importing and Exporting BPEL Exporting BPEL Use to export an orchestration to BPEL Review export restrictions (restricted shapes) Modify orchestration properties for export Export to BPEL from Solution Explorer Use to export an orchestration to BPEL Review export restrictions (restricted shapes) Modify orchestration properties for export Export to BPEL from Solution Explorer

11 Lesson 2: Building an Orchestration What Is the Orchestration Designer? Using Message and Data-Handling Shapes Working with Messages in an Orchestration Logical vs. Physical Ports Creating and Configuring Orchestration Ports Demonstration: Creating an Orchestration

12 What Is the Orchestration Designer? Process Area Port Surface Port Surface Toolbox Port Surface Port Surface Orchestration View Properties

13 Using Message and Data-Handling Shapes ShapeUse Receive Use to receive a message from a port Must specify message variable Can apply a filter expression Send Use to send a message to a port Must specify a message variable Construct Message Use to construct a new message instance Must always contain a Transform shape or Message Assignment shape Message Assignment Use to assign one message to another Uses Expression Editor to assign values Transform Use to move data between two messages Must specify input and output messages and a map

14 Orchestration Messages Messages are variables Messages are immutable You must define a message for every message instance used in an orchestration Messages are variables Messages are immutable You must define a message for every message instance used in an orchestration Working with Messages in an Orchestration Use Orchestration View to define: Variables Ports and port types Correlation sets and correlation types Messages and multi-part message types Variables Ports and port types Correlation sets and correlation types Messages and multi-part message types

15 Logical vs. Physical Ports Messages MessageBox Receive Port Receive Location (Physical Address) Subscriptions Bind/Enlist Orchestration Logical Send Port Logical Receive Port Send Port (Physical Address) 2 2

16 Creating and Configuring Orchestration Ports Orchestration Port Types Identifier Communication pattern One-way or Request-Response Modifier (internal, private, or public) Operations Message Types Identifier Communication pattern One-way or Request-Response Modifier (internal, private, or public) Operations Message Types Port Binding Specify now Specify later Direct Dynamic Specify now Specify later Direct Dynamic

17 Demonstration: Creating an Orchestration In this demonstration, you will see how to: Create message variables Create and configure a receive shape Create and configure a transform shape Create and configure a send shape Create a logical receive port Create a logical send port

18 Lesson 3: Monitoring Orchestrations Using the Group Hub to View Orchestrations Using the Orchestration Debugger Demonstration: Tracking an Orchestration Instance

19 Message Instance States Consumed Delivered (not consumed) Suspended, resumable Suspended, non-resumable Undelivered Undelivered (retrying) Undelivered (scheduled) Consumed Delivered (not consumed) Suspended, resumable Suspended, non-resumable Undelivered Undelivered (retrying) Undelivered (scheduled) Using the Group Hub to View Orchestrations Service Instance States Ready to run Scheduled Retrying Dehydrated Suspended, resumable Suspended, non-resumable Active In breakpoint Completed with discarded messages Ready to run Scheduled Retrying Dehydrated Suspended, resumable Suspended, non-resumable Active In breakpoint Completed with discarded messages

20 Using the Orchestration Debugger Orchestration Debugger View a rendered orchestration Set breakpoints View specific variables and message data Continue and resume debugging View a rendered orchestration Set breakpoints View specific variables and message data Continue and resume debugging

21 Demonstration: Tracking an Orchestration Instance In this demonstration, you will see how to: Use the BizTalk Group Hub to track message activity through an orchestration

22 Lab: Creating a BizTalk Orchestration Exercise 1:Import an Existing Schema and Map Exercise 2:Create a New Project and Orchestration Exercise 3:Create Orchestration Ports Exercise 4:Build, Deploy, and Test the Solution
