Establishing a Connection
Enabling SSIS in Visual Studio 2022
If you're using Visual Studio 2022, you will need to install the SQL Server Integration Services Projects extension to use SSIS.
- Navigate to Extensions > Manage Extensions.
- In the Manage Extensions window's search box, search for "SQL Server Integration Services Projects 2022" and select the extension in the list.
- Click Download.
- Close Visual Studio and run the downloaded Microsoft.DataTools.IntegrationServices.exe installer. Proceed through the installer with default settings.
- Open Visual Studio. There should now be an "Integration Services Project" project template available.
Adding the Oracle Eloqua Connection Manager
Create a new connection manager as follows:
- Create a Visual Studio project with the "Integration Services Project" template.
- In the project, right-click within the Connection Managers window and select New Connection from the menu.
- In the Description column, select CData Oracle Eloqua Connection Manager and click Add...
- Configure the component as described in the next section.
Alternatively, if you have an existing project and CData Oracle Eloqua Source or CData Oracle Eloqua Destination:
- Right-click your CData Oracle Eloqua source or destination component in your data flow
- Select Edit... to open an editor window.
- Click the New... button next to the Connection manager: dropdown selector to create a connection manager.
- Configure the component as described in the next section.
Authenticating to Oracle Eloqua
Oracle Eloqua supports both Basic (login) and OAuth authschemes.
Basic Authentication
Basic authentication runs over HTTP via SSL to enable users to connect via login.To use Basic authentication, specify these properties:
- AuthScheme: Basic.
- Company: The company's unique identifier.
- User: Your login account name.
- Password: Your login password.
OAuth Authentication
To enable OAuth authentication from all OAuth flows, you must set AuthScheme to OAuth and create a custom OAuth application.
The following subsections describe how to authenticate to Oracle Eloqua from the three most common authentication flows. For information about how to create a custom OAuth application, see Creating a Custom OAuth Application. For a complete list of connection string properties available in Oracle Eloqua, see Connection.
Desktop Applications
To authenticate with the credentials for a custom OAuth application, you must get and refresh the OAuth access token. After you do that, you are ready to connect.Get and refresh the OAuth access token:
- InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
- OAuthClientId: The client Id assigned when you registered your application.
- OAuthClientSecret: The client secret that was assigned when you registered your application.
- CallbackURL: The redirect URI that was defined when you registered your application.
When you connect, the component opens Oracle Eloqua's OAuth endpoint in your default browser. Log in and grant permissions to the application.
After you grant permissions to the application, the component completes the OAuth process:
- The component obtains an access token from Oracle Eloqua and uses it to request data.
- The OAuth values are saved in the path specified in OAuthSettingsLocation. These values persist across connections.
When the access token expires, the component refreshes it automatically.
Automatic refresh of the OAuth access token:
To have the component automatically refresh the OAuth access token:
- Before connecting to data for the first time, set these connection parameters:
- InitiateOAuth: REFRESH.
- OAuthClientId: The client Id in your application settings.
- OAuthClientSecret: The client secret in your application settings.
- OAuthAccessToken: The access token returned by GetOAuthAccessToken.
- OAuthSettingsLocation: The path where you want the component to save the OAuth values, which persist across connections.
- On subsequent data connections, set:
- InitiateOAuth
- OAuthSettingsLocation
Manual refresh of the OAuth access token:
The only value needed to manually refresh the OAuth access token is the OAuth refresh token.
- To manually refresh the OAuthAccessToken after the ExpiresIn period (returned by GetOAuthAccessToken) has elapsed, call the RefreshOAuthAccessToken stored procedure.
- Set these connection properties:
- OAuthClientId: The Client Id in your application settings.
- OAuthClientSecret: The Client Secret in your application settings.
- Call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken.
- After the new tokens have been retrieved, set the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken. This opens a new connection.
Store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.
Headless Machines
If you need to log in to a resource that resides on a headless machine, you must authenticate on another device that has an internet browser. You can do this in either of the following ways:
- Option 1: Obtain the OAuthVerifier value.
- Option 2: Install the component on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.
After you execute either Option 1 or Option 2, configure the driver to automatically refresh the access token on the headless machine.
Option 1: Obtaining and Exchanging a Verifier Code
To obtain a verifier code, you must authenticate at the OAuth authorization URL as follows:
-
Authenticate from the machine with an internet browser, and obtain the OAuthVerifier connection property.
Set these properties:
- InitiateOAuth: OFF.
- OAuthClientId: The client Id assigned when you registered your application.
- OAuthClientSecret: The client secret assigned when you registered your application.
-
Call the GetOAuthAuthorizationUrl stored procedure. The stored procedure returns the CallbackURL established when the custom OAuth application was registered. (See Creating a Custom OAuth Application.)
Copy this URL and paste it into a new browser tab.
-
Log in and grant permissions to the component. The OAuth application redirects you the redirect URI, with a parameter called code appended. Note the value of this parameter; you will need it later, to configure the OAuthVerifier connection property.
-
Exchange the OAuth verifier code for OAuth refresh and access tokens. On the headless machine, to obtain the OAuth authentication values, set these properties:
- InitiateOAuth: REFRESH.
- OAuthVerifier: The noted verifier code (the value of the code parameter in the redirect URI).
- OAuthSettingsLocation: Persist the encrypted OAuth authentication values to the specified file.
- OAuthClientId: The client Id in your custom OAuth application settings.
- OAuthClientSecret: The client secret in the custom OAuth application settings.
-
Test the connection to generate the OAuth settings file.
-
You are ready to connect after you re-set these properties:
- InitiateOAuth: REFRESH.
- OAuthSettingsLocation: The file containing the encrypted OAuth authentication values. To enable the automatic refreshing of the access token, be sure that this file gives read and write permissions to the component.
- OAuthClientId: The client Id assigned when you registered your application.
- OAuthClientSecret: The client secret assigned when you registered your application.
Option 2: Transferring OAuth Settings
Prior to connecting on a headless machine, you must install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described above in "Desktop Applications".
After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the path specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.
Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.
To connect to data via the headless machine, set these connection properties:
- InitiateOAuth: REFRESH
- OAuthSettingsLocation: The path to the OAuth settings file you copied from the machine with the browser. To enable automatic refreshing of the access token, ensure that this file gives read and write permissions to the component.
- OAuthClientId: The client Id assigned when you registered your custom OAuth application.
- OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
Using PASSWORD Grant
If you set OAuthGrantType to password, it may trigger an OAuth flow that passes credentials. In this case, there will be no browser window to authorize.To ensure that you are authenticated properly, set these connection properties:
- User: The user name.
- Company: The company's unique identifier.
- OAuthClientId The Client ID returned in your custom OAuth application settings. (See Creating a Custom OAuth Application.)
- OAuthClientSecret: The Client Secret returned in your custom OAuth application settings (See Creating a Custom OAuth Application.)
- OAuthGrantType: password.
- InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
