   • Note: If you are running a trial, just select the Trial Key option.
5. Both 32-bit and 64-bit drivers are included. Install both if you use applications with different architectures.

Linux Installation

1. Ensure UnixODBC is installed: sudo apt-get install unixodbc unixodbc-dev (Debian/Ubuntu) sudo yum install unixODBC unixODBC-devel (RHEL/CentOS)
2. Extract the driver package to /opt/cdata/
3. The driver will be automatically registered in /etc/odbcinst.ini

Activating Your License

You should have received your license key via email from the CData Orders Team. The license key looks like this: XXXX-XXXX-XXXX-XXXX-XXXX

Windows License Activation

Your license would typically be activated during installation. However, there are cases where you may need to activate it manually. The steps below walk you through manual activation:

1. Open the ODBC driver application from the Start menu.
2. Navigate to Help > Licensing
3. Enter your license key in the provided field.
4. Click Activate
5. You should see "Licensed" status confirming successful activation.

Linux License Activation

1. Navigate to the installation directory where you extracted the driver package. (i.e.cd /opt/cdata/cdata-odbc-driver-for-acumatica/bin/)
2. Create a license file by running the following command sudo ./install-license.sh
3. Replace with your actual license key.
4. To activate a trial, omit the input.

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 ServiceNow. The ODBC driver 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: Use the 64-bit version for 64-bit applications and the 32-bit version for 32-bit applications.
   • 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 ODBC Driver for ServiceNow from the list, or click Add to create a new data source.
4. Click OK or Finish to open the connection configuration dialog.

Linux: Editing Config Files (odbcinst.ini & odbc.ini)

1. Register the Driver by adding the section below to the odbcinst.ini file.
[CData ODBC Driver for ServiceNow] Driver=/opt/cdata/cdata-odbc-driver-for-servicenow/lib/libservicenowodbc.x64.so Description=CData ODBC Driver for ServiceNow
2. Save the file.
3. Create the DSN by adding the entry below to the odbc.ini file:
[CData ServiceNow Source] Driver=/opt/cdata/cdata-odbc-driver-for-servicenow/lib/libservicenowodbc.x64.so ConnectionProperty1=Value1 ConnectionProperty2=Value2 OAuthClientId = MyOAuthClientId OAuthClientSecret = MyOAuthClientSecret Username = MyUsername Password = MyPassword URL = https://myinstance12345.service-now-com InitiateOAuth = GETANDREFRESH
4. Save the file.

Configuring Connection Properties

ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, specify the Instance, Username, and Password connection properties.

See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

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.

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.

Driver Not Found (Linux)

Solution: Verify the driver is correctly registered in odbcinst.ini. Contact [email protected] for further assistance.

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

FAQs

Installation & Licensing

• Do I need administrator rights to install the driver?
  Yes, administrator rights are required for system-wide installation on Windows and Linux.
• Can I install both 32-bit and 64-bit drivers on the same machine?
  Yes, both versions are installed by default.

Connecting

• What's the difference between System DSN and User DSN?
  System DSNs are available to all users on a machine and are required for services. User DSNs are only available to the user who created them.
• Can I use a DSN-less connection string instead of creating a DSN?
  Yes. Many applications support DSN-less connection strings. See the connection string example below:

  Driver={CData ODBC Driver for ServiceNow};RequiredConnectionProperty1=Value1;RequiredConnectionProperty2=Value2;

• How do I connect to multiple ServiceNow accounts?
  Create separate DSNs for each account, each with its own authentication credentials.
• Can I connect through a proxy server?
  Yes. Configure proxy settings in your DSN connection properties. Refer to the Firewall & Proxy section in the help documentation for proxy configuration.

Performance & Troubleshooting
