Configure a Solicit-Response 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 solicit-response send port using the CData BizTalk Adapter for Azure Data Lake Storage. You can use a static solicit-response send port to execute commands and access the results in BizTalk. You can use send ports to execute updategram commands, SQL commands, and stored procedure operations.

Create and Configure the Send Port

Create a static solicit-response send port and configure it to use the 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 Solicit-Response Send Port. The Send Port Properties dialog is displayed.
3. In the Send Port properties, enter a name for the receive port.
4. In the Transport Type menu, select CData.ADLS;.
5. In the Send pipeline menu, select the default option, PassThruTransmit.
6. In the Receive pipeline menu, select the default option, PassThruReceive.

Configure the Adapter

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

1. In the send port properties, click the Configure button. The Adapter 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.

Refer to the "Adapter Configuration" chapter in the help documentation for a description of the various properties and their functions.

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, click Configure. The adapter properties dialog is displayed.
2. Click the button in the Connection String property. The Connection String Options dialog is displayed.
3. Enter the 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.

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

Refer to the "Connection String Options" chapter in the help documentation for a description of the various properties and their functions. The updategram tutorial for the adapter for Azure Data Lake Storage walks through the steps to create a simple application that uses a solicit-response send port to execute an insert updategram to Azure Data Lake Storage.
