Extract, Transform, and Load HCL Domino Data in Informatica PowerCenter

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for HCL Domino, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to create a simple Workflow in Informatica PowerCenter to extract HCL Domino data and load it into a flat file.

Add HCL Domino as an ODBC Data Source

If you have not already, install the driver on the PowerCenter server and client machines. On both machines, specify the connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Connecting to Domino

To connect to Domino data, set the following properties:

• URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
• DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.

Authenticating with Domino

Domino supports authenticating via login credentials or an Azure Active Directory OAuth application:

Login Credentials

To authenticate with login credentials, set the following properties:

• AuthScheme: Set this to "OAuthPassword"
• User: The username of the authenticating Domino user
• Password: The password associated with the authenticating Domino user

The driver uses the login credentials to automatically perform an OAuth token exchange.

AzureAD

This authentication method uses Azure Active Directory as an IdP to obtain a JWT token. You need to create a custom OAuth application in Azure Active Directory and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:

• AuthScheme: Set this to "AzureAD"
• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
• OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
• CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
• AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.

  The tenant ID is the same as the directory ID shown in the Azure Portal's Azure Active Directory > Properties page.

Create an ETL Workflow in PowerCenter

Follow the steps below to create a workflow in PowerCenter to pull HCL Domino data and push it into a flat file.

Create a Source Using the ODBC Driver

1. In PowerCenter Workflow Manager, add a new ODBC relational connection by going to Connections -> Relational, and in the first window select the ODBC type and click New.
2. In the Relational Connection Editor, set the name of the newly created connection and set the User Name and Password based on the credentials utilized to connect to your Repository. Under the Connection String input your System DSN, which by default is called 'CData Domino Sys'.
3. In PowerCenter Designer, connect to your repository and open your folder. If you do not already have a folder created, you will need to manually create a folder for your repository. To create a folder, open Informatica PowerCenter Repository Manager, connect to your Repository Service and go to Folder -> Create to create a new folder.
4. Select the Source Analyzer, click the sources menu, and select Import from Database...
5. In the drop-down menu for ODBC data source, select the DSN you previously configured (CData Domino Sys).
6. Click connect and select the tables and views to include.
7. Click OK.

Create a Flat File Target Based on the Source

1. Select the Target Designer and drag and drop the previously created source onto the workspace. Using the existing source copies the columns into the target.
2. Right-click the new target, click edit, and change the database type to flat file.

Create a Mapping to Between HCL Domino Data and a Flat File

1. Click on the Mapping Designer.
2. Drag the source and target to the workspace (name the new mapping, if prompted).
3. Right-click on the workspace and select Autolink by Name.
4. Drag the columns from the source qualifier to the target definition.
5. Save the folder (Ctrl + S).

Create Workflow Based on the Mapping

With the source, target, and mapping created and saved, you are now ready to create the workflow.

1. Right-click the mapping and select generate workflow to open the Workflow Generation wizard.
2. Create a workflow with a non-reusable session.
3. Ensure that you have properly configured the connection object and set the prefixes. If you have not already done so, you will need to create an Integration Service. To create an Integration Service, open your Administrator site, and under Domain, create a new PowerCenter Integration Service. Under the PowerCenter Repository Service, select the Repository you are referring to, and as Username and Password, use your Administrator login information.
4. Configure the Connection as needed.
5. Review the Workflow and click Finish.

With a workflow created, you can open the PowerCenter Workflow Manager to access and start the workflow, quickly transferring HCL Domino data into a flat file. With the CData ODBC Driver for HCL Domino, you can configure sources and targets in PowerCenter to integrate HCL Domino data into any of the elegant and powerful features in Informatica PowerCenter.
