Visualize HCL Domino Data in TIBCO Spotfire through OData

OData is a major protocol enabling real-time communication among cloud-based, mobile, and other online applications. The CData Connect Server provides HCL Domino data to OData consumers like TIBCO Spotfire. This article shows how to use the Connect Server and Spotfire's built-in support for OData to access HCL Domino data in real time.

Configuring Connect Server

To work with live HCL Domino data in TIBCO Spotfire, we need to connect to HCL Domino from Connect Server, provide user access to the new virtual database, and create OData endpoints for the HCL Domino data.

Add a Connect Server User

Create a User to connect to HCL Domino from TIBCO Spotfire through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to HCL Domino from Connect Server

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

1. Open Connect Server and click Connections
2. Select "HCL Domino" from Available Data Sources
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 Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add HCL Domino OData Endpoints in Connect Server

After connecting to HCL Domino, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the HCL Domino database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Create Data Visualizations on External HCL Domino Data

1. Open Spotfire and click Data -> Add data...
2. Then, click "Connect to" -> OData -> New Connection. In the OData Connection dialog, enter the following information:
   • Service URL: Enter the Connect Server's OData endpoint. For example: http://localhost:8080/odata.rsc
   • Authentication Method: Select Username and Password.
   • Username: Enter the username of a Connect Server user. You can create API users on the Security tab of the administration console.
   • Password: Enter the authtoken of a Connect Server user.
3. Select the tables and columns you want to add to the dashboard. This example uses ByName.

4. If you want to work with the live data, click the Keep Data Table External option. This option enables your dashboards to reflect changes to the data in real time.

   If you want to load the data into memory and process the data locally, click the Import Data Table option. This option is better for offline use or if a slow network connection is making your dashboard less interactive.

5. After you have selected a table, Spotfire uses the data to detect number, time, and other categories. You are now on your way to creating new visualizations for analytics, reporting, and more.
