Common Licensing Questions

Can I use my license on multiple machines?

Yes, depending on your subscription tier. Check your order confirmation or contact your account representative for details. If you are unsure of who your account representative is, contact [email protected].

I lost my license key. How do I retrieve it?

Email [email protected] with your order number, and we'll resend your license key.

Can I transfer my license to a different machine?

Yes. When transferring the license to a different machine, you will need to submit a License Transfer Request on our site linked below:

https://www.cdata.com/lic/transfer/

After the License Transfer Request is submitted and successfully processed, an activation will be added to your Product Key, and you will be able to activate the full license on the other machine. Once this process is finished, the license on the previous machine will be invalid.

For additional licensing questions, contact [email protected]. Viewing and upgrading your license can now be done through our self-service portal at portal.cdata.com.

Connection Configuration

Once your driver is installed and licensed, you're ready to configure a connection to MongoDB. The CData Power BI Connector for MongoDB is built on top of an ODBC driver, so it uses a DSN (Data Source Name) to store connection properties.

Creating a DSN

Windows: Using ODBC Data Source Administrator

1. Open the ODBC Data Source Administrator (64-bit)

   Note: CData Power BI connectors use the 64-bit version.

   • Search for "ODBC" in the Windows Start menu
   • Or navigate to: Control Panel -> Administrative Tools -> ODBC Data Sources
2. Click the System DSN or User DSN tab
   • System DSN: Available to all users on the machine (recommended for services)
   • User DSN: Available only to the current user
3. Select CData PBI MongoDB Source or Sys from the list (depending on User DSN or System DSN) or click Add to create a new data source.
4. Click Finish to open the connection configuration dialog.

Configuring Connection Properties

Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

👁 Configure the MongoDB DSN.

Testing Your Connection

1. After entering your connection properties, click Test Connection.
2. A successful test confirms:
   • Authentication credentials are correct.
   • Network connectivity is established.
   • Required permissions are in place.
3. If the test fails, the error message will indicate what needs to be corrected.
4. Click OK to save your DSN.

Creating a Connection in Power BI Desktop

1. Open Power BI Desktop.
2. Select Get Data -> More.
3. In the search box, type CData MongoDB.
4. Select the CData MongoDB connector and click Connect. 👁 Select CData MongoDB.
   
5. Enter the Data Source Name, in this case CData PBI MongoDB Sys.
6. Select Import if you want to import a copy of the data into your project. You can refresh this data on demand. Or select DirectQuery if you want to work with the remote data. 👁 Enter the DSN configured earlier and select a desired Data Connectivity mode.
   
7. Select the required tables in the Navigator dialog. Click Load to see the MongoDB data in Power BI. 👁 Load the MongoDB data.
   

Common Connection Issues

Authentication Failed

Solution: Verify your credentials are current. For OAuth applications, you may need to authorize CData in your application's security settings. Contact [email protected] for authorization assistance.

Cannot Reach Server

Solution: Check firewall & proxy settings. Contact [email protected] for specific port requirements.

Table Not Found

Solution: Verify database and schema names. Use the Data Model tab in the DSN configuration to browse available tables.

For additional connection troubleshooting, contact [email protected] with your specific error message.

What's Next

Now that you have installed, licensed, and configured the driver, here are some scenarios you can use to explore our Power BI Connectors:

---

Installation & Licensing

Do I need administrator rights to install the connector?

Yes. Administrator rights are required to install the CData Power BI Connector because the installer writes to system directories and registers required components.

Is the connector available in 32-bit and 64-bit versions?

No. Power BI Desktop is 64-bit only, and all CData Power BI Connectors are distributed as 64-bit only MSI installers.

Connecting

What's the difference between System DSN and User DSN?

System DSNs are available to all users on a machine and are required when using the Power BI On-premises Data Gateway. User DSNs are only available to the Windows user who created them and are suitable for local Power BI Desktop use.

Can I use a DSN-less connection string instead of creating a DSN?

Yes. The underlying ODBC driver supports DSN-less connection strings, and Power BI can use DSN-less configuration when connecting through the ODBC connector.

Example:

Driver={CData Power BI Connector for MongoDB};User=Value1;Password=Value2;SecurityToken=Value3;

(Exact properties depend on your MongoDB authentication method.)

How do I connect to multiple MongoDB accounts?

Create separate DSNs, one for each MongoDB account, or create separate connection entries inside Power BI using different authentication credentials. Each DSN or connection stores its own settings.

Can I connect through a proxy server?

Yes. Proxy settings can be configured in the connection properties of your DSN or through the connector's Advanced Settings in Power BI.

Refer to the Firewall & Proxy section of the documentation for required properties and supported proxy scenarios.

Performance & Troubleshooting

Why are my queries slow?

Check the following:

• Use Import mode if you are working with large datasets or performing heavy transformations. Import mode caches data locally and reduces the number of live API calls.
• Use DirectQuery only when required, as it sends every query to MongoDB in real time.
• Apply filters in Power Query to reduce the size of the dataset before loading.
• Avoid selecting all columns if only a subset is needed.
• Monitor MongoDB API limits, which can throttle performance.
• Contact [email protected] for help with query optimization and best practices.

How do I enable logging for troubleshooting?

Logging can be enabled through the connector's advanced connection properties in Power BI Desktop.

In the connection dialog:

• Expand Advanced Options
• Set:
  • Logfile = path to a writable log file
  • Verbosity = 3 (or higher for detailed logs)

Be prepared to upload the log file when contacting [email protected] for analysis securely.

What ports does the connector need access to?

Most MongoDB connections require outbound HTTPS (port 443) access. Ensure your firewall allows outbound secure traffic to MongoDB endpoints.

For environments using proxies or additional security layers, consult the Firewall & Proxy section of the connector documentation.

Can I use the connector in a Linux container or Docker?

No. The CData Power BI Connector cannot be used in Linux containers because:

• Power BI Desktop runs only on Windows
• Power BI Gateway runs only on Windows
• Custom connector .pqx files are supported only on Windows

The Power BI Connector is a Windows-only component.

General

Where can I find the complete list of supported SQL operations?

Refer to the SQL Compliance section of the MongoDB connector documentation. Note that available SQL features may differ between Import and DirectQuery mode due to Power BI engine limitations.

How often is the connector updated?

CData releases major updates to the Power BI Connector annually, with periodic maintenance updates as needed.

Check your CData Account Portal or contact [email protected] for the latest version.

Where can I find examples of using the connector?
