Receive Location

Messages received, processed, and published to the MessageBox database

2

The Publish and Subscribe Architecture

A filter expression defines properties of messages in which each subscriber is interested.

1

Message properties are evaluated to determine which subscribers require a copy of the message

3

XML or Flat File

A copy of the message is delivered to each subscriber

What Is Message Routing?

Send Port B

Send Port A

PO Message

Message Routing

Routes directly to a port Based on a filter expressionConfigured on the send port

Filter Expression PortIf CustomerName = Contoso A

If Price > 1000 B

If Qty > 500 and Price < 1000 C

Ports specify:

How messages are sent and received by BizTalkThe communication direction andcommunication patternThe location where messages are received or sent

Property promotion

Fields that you choose to promote within a message instanceMakes the data in the field accessible to BizTalk servicesQuick promotion automatically creates a property schema

What Is Property Promotion?

Demonstration: Promoting a Property

In this demonstration, you will see how to promote a schema property

Lesson 2: Configuring Message Routing

Steps for Enabling Message RoutingConfiguring a Receive Port and Receive LocationDemonstration: Configuring a Receive Port and a File Receive LocationCreating and Configuring a Send PortConfiguring Send Port Filters Using a Send Port GroupEnlisting and Starting a Send PortDemonstration: Configuring a Send Port and Send Port Group

Steps:

Start and enable the newly created ports5

Create and configure send port filters4

Create send ports or send port groups3

Create receive port and receive location2

Promote fields to be filtered1

Steps for Enabling Message Routing

Receive location properties:

Receive handler (host)Enabled or disabledStart/stop receiving (date)Operating window (time period)

Configuring a Receive Port and Receive Location

Demonstration: Configuring a Receive Port and a File Receive Location

In this demonstration, you will see how to:Create a receive portConfigure a receive port to use a BizTalk mapCreate a receive locationConfigure a receive locationEnable a receive location

Creating and Configuring a Send Port

Send port properties:Send port namePrimary and secondary transportAddress (URI)Retry countService window enabled/disabled

Configuring Send Port Filters

Filtering

Filter messages based on an expressionRoute to a send portExample: If the Amount is greater than or equal to $500, forward the message to a folder for approvalUse to subscribe to failed messages

Specify map

Send Port Group

Send port group:

A named collection of send portsUsed to send the same message to multiple destinationsCan be used to route based on message content by using a filter expression

Using a Send Port Group

Enlisted

Enlistment:

Port state determines if messages are to be routedUse BizTalk Explorer or BizTalk Administrator Console to change stateEnlisting creates a subscription in the MessageBox databaseStarting implies enlistment and begins the processing of messages

Port states:

Bound – no subscription (default)Stopped – subscribed and not receiving messagesStarted – subscribed and receiving messages
