Install and configure native client software on the machines where the Data Integration Service and PowerCenter Integration Service process runs and where you install Informatica Developer and the PowerCenter Client. To ensure compatibility between Informatica and databases, use the appropriate database client libraries. You must configure connectivity to the following Informatica components on Windows:
Integration Service.
Install the Teradata client, the Teradata ODBC driver, and any other Teradata client software that you might need on the machine where the Data Integration Service and PowerCenter Integration Service run. You must also configure ODBC connectivity.
Informatica Developer.
Install the Teradata client, the Teradata ODBC driver, and any other Teradata client software that you might need on each machine that hosts a Developer tool that accesses Teradata. You must also configure ODBC connectivity.
PowerCenter Client.
Install the Teradata client, the Teradata ODBC driver, and any other Teradata client software that you might need on each PowerCenter Client machine that accesses Teradata. Use the Workflow Manager to create a database connection object for the Teradata database.
Based on a recommendation from Teradata, Informatica uses ODBC to connect to Teradata. ODBC is a native interface for Teradata.
