The Teradata Multiload utility provides the capability to perform batch maintenance on tables (insert, update, delete and upsert). It loads data from external sources and provides the capability to restart jobs interrupted by errors, exceptions and failures.

In the first article in this series on Teradata Error Handling, we introduced the larger architecture and load utility environment. in this article the focus will be on the Fastload Utility and some of the techniques applicable to handling errors, exceptions and failures that can occur within a High Availability system.

A high-availability system must have the ability to identify and correct errors, exceptions and failures in a timely and reliable manner to meet challenging service level objectives. The Teradata database and the utilities and components (used to both load and access data) provide capabilities to implement reliable error and exception handling functionality. These capabilities combined with a well designed high availability architecture allow a Teradata Active Enterprise Intelligence (AEI) system to meet the service level objectives required to support mission critical business processes.
