Build DB2-Connected ETL Processes in Google Data Fusion

Google Data Fusion allows users to perform self-service data integration to consolidate disparate data. Uploading the CData JDBC Driver for IBM DB2 enables users to access live DB2 data from within their Google Data Fusion pipelines. While the CData JDBC Driver enables piping DB2 data to any data source natively supported in Google Data Fusion, this article walks through piping data from DB2 to Google BigQuery,

Upload the CData JDBC Driver for IBM DB2 to Google Data Fusion

Upload the CData JDBC Driver for IBM DB2 to your Google Data Fusion instance to work with live DB2 data. Due to the naming restrictions for JDBC drivers in Google Data Fusion, create a copy or rename the JAR file to match the following format driver-version.jar. For example: cdatadb2-2020.jar

1. Open your Google Data Fusion instance
2. Click the to add an entity and upload a driver
3. On the "Upload driver" tab, drag or browse to the renamed JAR file.
4. On the "Driver configuration" tab:
   • Name: Create a name for the driver (cdata.jdbc.db2) and make note of the name
   • Class name: Set the JDBC class name: (cdata.jdbc.db2.DB2Driver)
5. Click "Finish"

Connect to DB2 Data in Google Data Fusion

With the JDBC Driver uploaded, you are ready to work with live DB2 data in Google Data Fusion Pipelines.

1. Navigate to the Pipeline Studio to create a new Pipeline
2. From the "Source" options, click "Database" to add a source for the JDBC Driver
3. Click "Properties" on the Database source to edit the properties

   NOTE: To use the JDBC Driver in Google Data Fusion, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

   • Set the Label
   • Set Reference Name to a value for any future references (i.e.: cdata-db2)
   • Set Plugin Type to "jdbc"
   • Set Connection String to the JDBC URL for DB2. For example:
     
     jdbc:db2:RTK=5246...;Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;

     Set the following properties to connect to DB2:

     • Server: Set this to the name of the server running DB2.
     • Port: Set this to the port the DB2 server is listening on.
     • Database: Set this to the name of the DB2 database.
     • User: Set this to the username of a user allowed to access the database.
     • Password: Set this to the password of a user allowed to access the database.

     You will also need to install the corresponding DB2 driver:

     • Windows: Install the IBM Data Server Provider for .NET.

       On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

     • Java: Install the IBM Data Server Driver for JDBC.

       In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the DB2 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.db2.jar

     Fill in the connection properties and copy the connection string to the clipboard.

   • Set Import Query to a SQL query that will extract the data you want from DB2, i.e.:
     SELECT * FROM Orders
4. From the "Sink" tab, click to add a destination sink (we use Google BigQuery in this example)
5. Click "Properties" on the BigQuery sink to edit the properties
   • Set the Label
   • Set Reference Name to a value like db2-bigquery
   • Set Project ID to a specific Google BigQuery Project ID (or leave as the default, "auto-detect")
   • Set Dataset to a specific Google BigQuery dataset
   • Set Table to the name of the table you wish to insert DB2 data into

With the Source and Sink configured, you are ready to pipe DB2 data into Google BigQuery. Save and deploy the pipeline. When you run the pipeline, Google Data Fusion will request live data from DB2 and import it into Google BigQuery.

While this is a simple pipeline, you can create more complex DB2 pipelines with transforms, analytics, conditions, and more. Download a free, 30-day trial of the CData JDBC Driver for IBM DB2 and start working with your live DB2 data in Google Data Fusion today.
