Import HCL Domino Data Using Azure Data Factory

Microsoft Azure Data Factory (ADF)) is a completely managed, serverless data integration service. When combined with CData Connect Cloud, ADF enables immediate cloud-to-cloud access to HCL Domino data within data flows. This article outlines the process of connecting to HCL Domino through Connect Cloud and accessing HCL Domino data within ADF.

CData Connect Cloud offers a cloud-to-cloud interface tailored for HCL Domino, granting you the ability to access live data from HCL Domino data within Azure Data Factory without the need for data replication to a natively supported database. Equipped with optimized data processing capabilities by default, CData Connect Cloud seamlessly channels all supported SQL operations, including filters and JOINs, directly to HCL Domino. This harnesses server-side processing to expedite the retrieval of the desired HCL Domino data.

Configure HCL Domino Connectivity for ADF

Connectivity to HCL Domino from Azure Data Factory is made possible through CData Connect Cloud. To work with HCL Domino data from Azure Data Factory, we start by creating and configuring a HCL Domino connection.

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "HCL Domino" from the Add Connection panel
3. Enter the necessary authentication properties to connect to HCL Domino.

   Prerequisites

   The connector requires the Proton component to be installed. Normally, Proton is distributed as part of the AppDev pack. See the HCL documentation for instructions on acquiring and installing Proton or the AppDev pack.

   Once the Proton service is installed and running, you will also need to create a user account and download its Internet certificate. This certificate can be used to set the connector certificate connection properties.

   Authenticating to Domino

   • Server: The name or IP address of the server running Domino with the Proton service.
   • Port: The port number that the Proton service is listening on.
   • Database: The name of the database file, including the .nsf extension.
   • SSLClientCertType: This must match the format of the certificate file. Typically this will be either PEMKEY_FILE for .pem certificates or PFXFILE for .pfx certificates.
   • SSLClientCert: The path to the certificate file.
   • SSLServerCert: This can be set to (*) if you trust the server. This is usually the case, but if you want to perform SSL validation, you may provide a certificate or thumbprint instead. See the documentation for SSLServerCert for details.

   Additional Server Configuration

   The connector supports querying Domino views if any are defined. Before views can be queried by the connector they must be registered with the design catalog.

   Please refer to the Catalog Administration section of the AppDev pack documentation for details on how to do this.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add HCL Domino Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to HCL Domino data from Azure Data Factory.

Access Live HCL Domino Data in Azure Data Factory

To establish a connection from Azure Data Factory to the CData Connect Cloud Virtual SQL Server API, follow these steps.

1. Login to Azure Data Factory.
2. If you have not yet created a Data Factory, Click New -> Dataset.
3. In the search bar, enter SQL Server and select it when it appears. On the following screen, enter a name for the server. In the Linked service field, select New.
4. Enter the connection settings.
   • Name - enter a name of your choice.
   • Server name - enter the Virtual SQL Server endpoint and port separated by a comma: tds.cdata.com,14333
   • Database name - enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, Domino1).
   • User Name - enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, test@cdata.com.
   • Password - select Password (not Azure Key Vault) and enter the PAT you generated on the Settings page.
   • Click Create.
5. In Set properties, set the Name, choose the Linked service we just created, select a Table name from those available, and Import schema from connection/store. Click OK.
6. After creating the linked service, the following screen should appear:
7. Click preview data to see the imported HCL Domino table.
You can now use this dataset when creating data flows in Azure Data Factory.
