Set up Teradata data source support

A federated database system enables users and applications to refer to multiple database management systems or databases within a single SQL statement. You can, for example, perform a UNION between a DB2(R) table and a Teradata view. A federated system includes a DB2 instance and database, and one or more data sources. Each data source consists of a non-DB2 DBMS and data.

In WebSphere(R) Information Integration Relational Wrappers, different wrappers are provided to allow your DB2 server to access different data sources. Wrappers are available for Oracle, Sybase, MS SQL Server, and Teradata. Wrappers for Informix(R) data sources are available as part of DB2 server products.

Before setting up WebSphere Information Integration Relational Wrappers, you must do two things:

  1. Install and configure the Teradata client software on the federated server system. The Teradata client software must be obtained from Teradata.
  2. The Teradata client software must be configured to connect to the data source.

    It is recommended to test this connection using query tools of the data source vendor so that any problem encountered with server definitions can be isolated to the installation and configuration of either:

    • The data source client software
    • The installation and configuration of your DB2 product and WebSphere Information Integration Relational Wrappers

To set up WebSphere Information Integration Relational Wrappers for Teradata data sources, type the required information in the Path to libcliv2.so library and Path to errmsg.cat file text fields. Click [...] to invoke the path browsers. Here are the default locations:

The DB2 Setup wizard will install a wrapper for the data source and set up WebSphere Information Integration Relational Wrappers to access it.

You can set up WebSphere Information Integration Relational Wrappers for data sources later by using the DB2 Setup wizard or the Command Line Processor (CLP).
