Configure a One-Way Send Port for the CData BizTalk Adapter for Azure Data Lake Storage

This section provides step-by-step instructions for creating, configuring, and testing a static one-way send port using the CData BizTalk Adapter for Azure Data Lake Storage. You can use static one-way send ports to execute updategrams, SQL commands, and stored procedures. Send ports are useful for operations that modify Azure Data Lake Storage data but do not have any response data. Typically, this would be DELETE or UPDATE SQL commands or updategrams, and occasionally stored procedure operations.

If you want to trigger actions that will return a response, such as executing SELECT commands or retrieving the Id of a record that you have created, use a solicit-response send port.

Create and Configure the One-Way Send Port

Create a static one-way send port and configure it to use the Azure Data Lake Storage adapter as its transport type.

1. If you have not already done so, open your BizTalk application in the BizTalk Administration Console.
2. In the node for your BizTalk application, right-click Send Ports and select New -> Static One-Way Send Port. The send port properties dialog is displayed.
3. In the Name menu, enter a name for the send port.
4. In the Type menu, select CData.ADLS.
5. In the Send Pipeline menu, select the default option, PassThruTransmit.

Configure the Adapter

Define the command that the adapter will execute in the Transport Properties dialog.

1. In the send port properties, click the Configure button. The CData.Azure Data Lake Storage Transport Properties dialog is displayed.
2. In the CommandType property, select the command type you want.
3. If you want to execute an SQL command, enter the command in the SQL Command box.

Configure the Connection to Azure Data Lake Storage

Configure credentials and other properties required to connect to Azure Data Lake Storage in the Connection String Options dialog.

1. In the send port properties dialog, click Configure. The adapter properties dialog is displayed.
2. Click the button in the Connection String property.
3. Click the box in the Connection String property. The Connection String Options dialog is displayed.
4. Enter connection properties. Below is a typical connection string: Schema=ADLSGen2;Account=myAccount;FileSystem=myFileSystem;AccessKey=myAccessKey;InitiateOAuth=GETANDREFRESH

   Authenticating to a Gen 1 DataLakeStore Account

   Gen 1 uses OAuth 2.0 in Azure AD for authentication.

   For this, an Active Directory web application is required. You can create one as follows:

   1. Sign in to your Azure Account through the .
   2. Select "Azure Active Directory".
   3. Select "App registrations".
   4. Select "New application registration".
   5. Provide a name and URL for the application. Select Web app for the type of application you want to create.
   6. Select "Required permissions" and change the required permissions for this app. At a minimum, "Azure Data Lake" and "Windows Azure Service Management API" are required.
   7. Select "Key" and generate a new key. Add a description, a duration, and take note of the generated key. You won't be able to see it again.

   To authenticate against a Gen 1 DataLakeStore account, the following properties are required:

   • Schema: Set this to ADLSGen1.
   • Account: Set this to the name of the account.
   • OAuthClientId: Set this to the application Id of the app you created.
   • OAuthClientSecret: Set this to the key generated for the app you created.
   • TenantId: Set this to the tenant Id. See the property for more information on how to acquire this.
   • Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.

   Authenticating to a Gen 2 DataLakeStore Account

   To authenticate against a Gen 2 DataLakeStore account, the following properties are required:

   • Schema: Set this to ADLSGen2.
   • Account: Set this to the name of the account.
   • FileSystem: Set this to the file system which will be used for this account.
   • AccessKey: Set this to the access key which will be used to authenticate the calls to the API. See the property for more information on how to acquire this.
   • Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.

5. Click Test Connection to verify the values and test connectivity.

After you connect successfully and define the command the adapter will execute, the send port is ready for use. See the following section for an example of using a one-way send port in a simple application. The application reads updategram commands contained in a file and uses a send port to execute the command.

In the example, filters are used to move the messages that contain the updategram from the receive location to the send port. See the following section for more information on filters.

Create Filters to Route BizTalk Messages Through an Application

To associate a send port with the messages you want, create a filter rule in the Filters section of the properties for that send port. Messages matching the criteria will be routed to the send port. See the following example to filter on a receive location.

Example: Execute Updategrams with a One-Way Send Port

This section shows how to use a one-way send port in a simple application. The application reads updategram commands contained in a file and executes the commands:

1. A one-way receive location picks up the XML document containing the updategram.
2. The receive location creates a BizTalk message containing the results of the command.
3. A one-way send port filters on the URI of the receive location. The document is routed to the one-way send port.
4. The send port executes the updategram command.

As in the preceding example, the followings steps show how to set up a receive location to read updategrams from a file and use a send port to execute the commands:

1. Create and configure a static one-way receive location. Use the File transport type. You can follow the same procedure to create and configure a receive location for the CData BizTalk Adapter for Azure Data Lake Storage.
2. Create a static one-way send port.
3. In the send port properties, click Filters.
4. In an empty property, set the following values:

   Property

   Select BTS.InboundTransportLocation from the menu.

   Value

   Enter the URI of the newly created one-way receive location.
