Access Live IBM Cloud Data Engine Data in TIBCO Data Virtualization

TIBCO Data Virtualization (TDV) is an enterprise data virtualization solution that orchestrates access to multiple and varied data sources. When paired with the CData TIBCO DV Adapter for IBM Cloud Data Engine, you get federated access to live IBM Cloud Data Engine data directly within TIBCO Data Virtualization. This article walks through deploying an adapter and creating a new data source based on IBM Cloud Data Engine.

With built-in optimized data processing, the CData TIBCO DV Adapter offers unmatched performance for interacting with live IBM Cloud Data Engine data. When you issue complex SQL queries to IBM Cloud Data Engine, the adapter pushes supported SQL operations, like filters and aggregations, directly to IBM Cloud Data Engine. Its built-in dynamic metadata querying allows you to work with and analyze IBM Cloud Data Engine data using native data types.

Deploy the IBM Cloud Data Engine TIBCO DV Adapter

1. In a console, navigate to the bin folder in the TDV Server installation directory. If there is a current version of the adapter installed, you will need to undeploy it.

   .\server_util.bat -server localhost -user admin -password ******** -undeploy -version 1 -name IBMCloudDataEngine
   

2. Extract the CData TIBCO DV Adapter to a local folder and deploy the JAR file (tdv.ibmclouddataengine.jar) to the server from the extract location.

   .\server_util.bat -server localhost -user admin -password ******** -deploy -package /PATH/TO/tdv.ibmclouddataengine.jar
   

You may need to restart the server to ensure the new JAR file is loaded properly, which can be accomplished by running the composite.bat script located at: C:\Program Files\TIBCO\TDV Server <version>\bin. Note that reauthenticating to the TDV Studio is required after restarting the server.

Sample Restart Call

.\composite.bat monitor restart

Authenticate with IBM Cloud Data Engine Using OAuth

Since IBM Cloud Data Engine authenticates using the OAuth protocol and TDV Studio does not support browser-based authentication internally, you will need to create and run a simple Java application to retrieve the OAuth tokens. Once retrieved, the tokens are used to connect to IBM Cloud Data Engine directly from the adapter.

The following code sample shows how to authenticate with IBM Cloud Data Engine. You will simply need to execute the Java application with the tdv.ibmclouddataengine.jar file in the class path.

IBMCloudDataEngineOAuth oauth = new IBMCloudDataEngineOAuth();  
oauth.generateOAuthSettingsFile("InitiateOAuth=GETANDREFRESH;" + 
                                  "Api Key=MyAPIKey;Instance CRN=myInstanceCRN;Region=myRegion;Schema=mySchema;OAuth Client Id=myOAuthClientId;OAuth Client Secret=myOAuthClientSecret;" + 
                                  "OAuthSettingsLocation=C:\ibmclouddataengine\OAuthSettings.txt;");

Once you deploy the adapter and authenticate, you can create a new data source for IBM Cloud Data Engine in TDV Studio.

Create a IBM Cloud Data Engine Data Source in TDV Studio

With the CData TIBCO DV Adapter for IBM Cloud Data Engine, you can easily create a data source for IBM Cloud Data Engine and introspect the data source to add resources to TDV.

Create the Data Source

1. Right-click on the folder you wish to add the data source to and select New -> New Data Source.
2. Scroll until you find the adapter (e.g. IBM Cloud Data Engine) and click Next.
3. Name the data source (e.g. CData IBM Cloud Data Engine Source).

4. Fill in the required connection properties.

   IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

   NOTE: Set the OAuthSettingsLocation property in the DV Adapter to the same value you used when performing the OAuth authentication (see above).

5. Click Create & Close.

Introspect the Data Source

Once the data source is created, you can introspect the data source by right-clicking and selecting Open. In the dashboard, click Add/Remove Resources and select the Tables, Views, and Stored Procedures to include as part of the data source. Click Next and Finish to add the selected IBM Cloud Data Engine tables, views, and stored procedures as resources.

After creating and introspecting the data source, you are ready to work with IBM Cloud Data Engine data in TIBCO Data Virtualization just like you would any other relational data source. You can create views, query using SQL, publish the data source, and more.
