Create Informatica Mappings From/To a JDBC Data Source for DB2

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData JDBC Driver for DB2, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse DB2 data in Informatica PowerCenter.

Deploy the Driver

To deploy the driver to the Informatica PowerCenter server, copy the CData JAR and .lic file, located in the lib subfolder in the installation directory, to the following folder: Informatica-installation-directory\services\shared\jars\thirdparty.

To work with DB2 data in the Developer tool, you will need to copy the CData JAR and .lic file, located in the lib subfolder in the installation directory, into the following folders:

• Informatica-installation-directory\client\externaljdbcjars
• Informatica-installation-directory\externaljdbcjars

Create the JDBC Connection

Follow the steps below to connect from Informatica Developer:

1. In the Connection Explorer pane, right-click your domain and click Create a Connection.
2. In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select JDBC.
3. In the JDBC Driver Class Name property, enter:

   cdata.jdbc.db2.DB2Driver

4. In the Connection String property, enter the JDBC URL, using the connection properties for DB2.

   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.

   A typical connection string is below:

   jdbc:db2:Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;

Browse DB2 Tables

After you have added the driver JAR to the classpath and created a JDBC connection, you can now access DB2 entities in Informatica. Follow the steps below to connect to DB2 and browse DB2 tables:

1. Connect to your repository.
2. In the Connection Explorer, right-click the connection and click Connect.
3. Clear the Show Default Schema Only option. 👁 The driver models DB2 entities as relational tables. (Salesforce is shown.)
   

You can now browse DB2 tables in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.

Create DB2 Data Objects

Follow the steps below to add DB2 tables to your project:

1. Select tables in DB2, then right-click a table in DB2, and click Add to Project.
2. In the resulting dialog, select the option to create a data object for each resource.
3. In the Select Location dialog, select your project.

   Create a Mapping

   Follow the steps below to add the DB2 source to a mapping:

   1. In the Object Explorer, right-click your project and then click New -> Mapping.
   2. Expand the node for the DB2 connection and then drag the data object for the table onto the editor.
   3. In the dialog that appears, select the Read option.

   Follow the steps below to map DB2 columns to a flat file:

   1. In the Object Explorer, right-click your project and then click New -> Data Object.
   2. Select Flat File Data Object -> Create as Empty -> Fixed Width.
   3. In the properties for the DB2 object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
   4. Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
   5. Click and drag to connect columns.

   To transfer DB2 data, right-click in the workspace and then click Run Mapping.

   👁 The completed mapping. (Salesforce is shown.)
