Managing the Teradata Connector

The Composer Teradata connector lets you access the data available in Teradata databases using the Composer client. The Composer Teradata connector supports Teradata version 16.20.

Before you can establish a connection from Composer to Teradata storage, a connector server needs to be installed and configured. See Managing Connectors and Connector Servers for general instructions and Connecting to Teradata for details specific to the Teradata connector.

After the connector has been set up, you can create data source configurations that specify the necessary connection information and identify the data you want to use. See Manage Composer v6 Data Source Configurations for more information. After data sources are configured, they can be used to create dashboards and visuals from your data. See Creating Dashboards.

Connecting to Teradata

The Teradata connector requires a JDBC driver to be configured before you can connect to your data source. You can download the driver from the vendor's site. If you are upgrading, keep in mind you need to configure the JDBC driver - see Upgrade the Composer v6 Server for instructions. For more information and steps, see Adding a JDBC Driver.

You can limit the list of available collections in a Teradata data store to collections from a specific schema specified in the Teradata JDBC URL. Use the Teradata JDBC URL database property to limit the list of available schemas as well as the list of available collections to collections from the schema.  For example:

jdbc:teradata://<url>/dbs_port=<port>,database=<schema>

Be sure to work with your Teradata database administrator when you do this.
