BAM End-to-End (BizTalk Server Sample)

  • Artigo

The End-to-End sample demonstrates how to correlate events from multiple components (in this case, three orchestrations and a pipeline) by using BAM.

BAM reconstructs the business activity that spans the pipeline component and orchestrations. At the lowest level, this works by calls to EventStream.EnableContinuation from each implementation component that expects more events for the activity. The call to EnableContinuation is explicit, while calls in Orchestration1 and Orchestration2 are made by adding a Continuation folder to the Tracking profile in one schedule, and a ContinuationID folder to the schedule that follows it.

The following diagram illustrates the workflow used in the sample.

What This Sample Does

The BAM end-to-end sample shows how you can use BAM to gather information from a pipeline and multiple orchestrations and update a single activity.

How This Sample Was Designed and Why

The BAM end-to-end sample was designed to illustrate the following activities:

  • Using BAM within a pipeline.

  • Using the Tracking Profile Editor (TPE) to map activity items to shapes in an orchestration and elements of a message.

  • Using continuations to keep an activity active when multiple pieces of a solution contribute to the activity.

The sample works as follows:

  1. An input message is retrieved from the <Samples Path>\BamEndToEnd\Input folder.

  2. The pipeline component assigns a unique DocumentID to the message, and uses the BAM API to begin a new BAM activity. The DocumentID is attached as a separate part of the input message to make it available to the orchestrations.

  3. The service Orchestration1 is activated when the input message is received.

  4. Orchestration1 modifies the input message and passes it as a parameter to Orchestration2.

  5. Orchestration2 modifies the input message and sends it to the MessageBox database, which activates Orchestration3.

  6. Orchestration3 modifies the message and writes it to the folder <Samples Path>\BamEndToEnd\Output.

  7. Each orchestration updates activity items in the BAM activity.

How to Use This Sample

Use the following procedures to build and run the BAM End-to-End sample:

Build and initialize this sample

  1. Open a command prompt as Administrator, and run <Samples Path>\BAM\BAMEndToEnd\Setup.bat. Setup.bat builds and initializes the BAM infrastructure for this sample. Keep the command prompt open.

  2. Create a tracking profile to map Orchestration1, Orchestration2, and Orchestration3 to the BAM activity. (Because creating the tracking profile is a complex process, the detailed instructions are in a separate procedure called To create a tracking profile. This procedure appears later in this document.)

  3. Deploy the tracking profile BamEndToEnd.btt that you created in the previous step. In the command prompt change to the <Samples Path>\BAM\BamEndToEnd directory. To deploy the tracking profile, type the following line, and then press Enter:

    “<BizTalkInstallationPath>\Tracking\bttdeploy” BamEndToEnd.btt

    How to Deploy Tracking Profiles with the Tracking Profiles Management Utility provides more information.

    Important

    You can ignore the message that the ContinuationID Orch1_ does not have a matching Continuation. This message is expected, because the continuation named Orch1_ is defined in the pipeline component, and not in the tracking profile.

Run this sample

Copy the file <Samples Path>\BamEndToEnd\InputMessage.xml into the folder <Samples Path>\BamEndToEnd\Input. After a few seconds, the message disappears from the Input folder, and an output message appears in the <Samples Path>\BamEndToEnd\Output folder.

View the BAM data

  1. Open SQL Server Management Studio.

  2. In SQL Server Management Studio, expand the server, expand Databases, expand BAMPrimaryImport, and then expand Tables.

  3. Right-click dbo.bam_EndToEndActivity_Completed, and then click Open Table. If you are using SQL Server, click Select top 1000 rows.

    The contents of the bam_EndToEndActivity_Completed table are displayed in the right pane. Each row in the table represents an EndToEndActivity activity that has been completed.

Rerun this sample

  1. Open a command prompt as Administrator, and change to the <Samples Path>\BAM\BamEndToEnd directory. Type the following line:

    “C:\Program Files\Microsoft BizTalk Server <version>\Tracking\bttdeploy” BamEndToEnd.btt /remove

    Note

    If you did not install BizTalk Server to the C drive, replace "C" with the drive letter where you installed BizTalk Server.

  2. Run <Samples Path>\BAM\BAMEndToEnd\Cleanup.bat. Cleanup.bat removes the BAM infrastructure for this sample.

  3. Perform the steps in To build and initialize this sample section in this topic.

Create a tracking profile

  1. Click Start, point to All Programs, point to Microsoft BizTalk Server 20xx. Right-click Tracking Profile Editor, and Run as administrator.

  2. In the left pane of the Tracking Profile Editor window, click Click here to import a BAM Activity Definition.
