How to publish and share HCL Domino Data dashboards with Tableau Server

Integrate connectivity to HCL Domino data into your enterprise reporting capabilities. The CData ODBC Driver for HCL Domino enables you to access live HCL Domino data in business intelligence tools like Tableau Server. Connectivity to HCL Domino APIs enables you to monitor changes to your data in real time. Other members of your organization can access your dashboards from a Web browser and get updates from their mobile phone.

This article walks through the process of configuring a DSN on the client and server machines, publishing a data source for HCL Domino to Tableau Server, and publishing an entire Workbook to Tableau Server (including the data source). If you publish a data source, you will be able to create new, refreshable workbooks in Tableau Server.

Connect to HCL Domino as an ODBC Data Source

To create a data source or workbook in Tableau Desktop and publish the data source or workbook to Tableau server, you will need to configure a DSN on each machine (Desktop and Server), specifying connection properties and creating DSNs using the same name on each machine. Information for connecting to HCL Domino follows, along with different instructions for configuring a DSN in Windows and Linux environments.

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.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you are installing the CData ODBC Driver for HCL Domino on Windows, DSN configuration is the last step of the driver installation. If you already have the driver installed, or you wish to configure new DSNs, you can use the Microsoft ODBC Data Source Administrator.

Linux

If you are installing the CData ODBC Driver for HCL Domino in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Publish the HCL Domino Data Source to Tableau Server

With the connections to HCL Domino data configured, you are ready to publish a HCL Domino data source on Tableau, ready to be leveraged by users in your organization to create workbooks based on HCL Domino data.

Create and Publish a Data Source

1. In the Connect pane, click More -> Other Databases (ODBC). Select CData Domino Sys, the system DSN.

   The driver installation automatically creates matching user and system DSNs: The system DSN is needed to connect from Tableau Server.

2. In the Database menu, select CData.
3. In the Table box, enter a table name or click New Custom SQL to enter an SQL query.
4. Drag the table onto the join area.
5. From the Server menu, click Publish Data Source -> (YOUR DATA SOURCE).
6. Enter the URL to the server. For most instances, you will authenticate with the Tableau Server username and password. Other authentication scenarios can be found below:
   • If Tableau is configured to use Kerberos and your computer has valid Active Directory credentials, Tableau connects to the server.
   • If Tableau is configured to use SAML, a login prompt for your external identity provider is displayed.
   • If Tableau is configured to use Active Directory, enter your Windows username and password.
7. In the resulting dialog, set the Project, Data Source, and other properties. If you want to schedule refreshes, select Embedded Password in the Authentication menu. Click Publish.

You and other users in your organization can now create and share workbooks based on the published data source.

Refresh Workbooks

With a system DSN configured on the client (Tableau Desktop) machine and server (Tableau Server) machine, you can refresh workbooks connected to the HCL Domino data source. From the Web interface for Tableau Sever, click Data -> (YOUR DATA SOURCE) -> Refresh.

Publish a Completed Workbook with HCL Domino Data to Tableau Server

If you have a specific Workbook that you wish to share with your organization, you can create the Workbook on Tableau Desktop and publish the Workbook directly to Tableau Server.

1. To connect to HCL Domino and select data, follow steps 1-5 above.
2. Click Server -> Sign in and configure the connection to the server. For most instances, you will authenticate with the Tableau Server username and password. Other authentication scenarios can be found below:
   • If Tableau is configured to use Kerberos and your computer has valid Active Directory credentials, Tableau connects to the server.
   • If Tableau is configured to use SAML, a login prompt for your external identity provider is displayed.
   • If Tableau is configured to use Active Directory, enter your Windows username and password.
3. With the data selected, select dimensions and measures to visualize and select a type of chart or graph to build your visualization(s).
4. Once the Workbook is complete, click Server -> Publish Workbook to publish the Workbook to Tableau Server.
5. In the resulting dialog, set the Project, Name, Description and other properties. If you want to schedule refreshes, click Edit under Data Sources and change the Authentication option to Embedded Password. Click Publish.

You and other users in your organization can now review the published workbook from Tableau Server.
