HCL Domino Icon HCL Domino ODBC Driver

The HCL Domino ODBC Driver is a powerful tool that allows you to connect with live data from HCL Domino, directly from any applications that support ODBC connectivity.

Access HCL Domino data like you would a database - read, write, and update HCL Domino FALSE, etc. through a standard ODBC Driver interface.

Viewing HCL Domino Data in RAD Studio Data Explorer


How to view HCL Domino data in RAD Studio Data Explorer using the CData ODBC Driver for HCL Domino.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for HCL Domino, you gain access to live HCL Domino data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve HCL Domino data. This article will walk through connecting to HCL Domino using the Data Explorer.

Configure a Connection to HCL Domino

If you have not already, first specify 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.

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.

Connecting to HCL Domino Data Using Data Explorer

You can create a simple application for displaying HCL Domino data by utilizing the CData FireDAC Components for HCL Domino and a new VCL Forms Application:

  1. Open the Data Explorer in RAD Studio and expand FireDAC.
  2. Right-click the ODBC Data Source node in the Data Explorer.
  3. Click Add New Connection.
  4. Enter a name for the connection.
  5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for HCL Domino.
  6. Back in the Data Explorer, expand the views for the connection.

  7. Create a new VCL Forms application and drag a view (for example: ByName) onto the form.

  8. Select the ByNameView object on the form and set the Active property to true.

  9. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

  10. Arrange the TStringGrid on the form and run the application to see the ByName data.
