Unity Director 14.00 provides user and query routing between multiple Teradata systems. This satisfies two requirements – routing users to a system that has data to satisfy their queries and re-routing users during planned or unplanned system outages. Hence, end users receive the ultimate benefit of continuous, transparent access to data. In addition, Unity Director provides high availability, disaster recovery, and data synchronization for multiple Teradata systems. For more information on Unity Director 14.00 please follow the links provided at the end of this article.

In this article, I will provide details of various routing rules that can be created using Unity Director 14.00. One can choose from various routing rule modes Auto, Preferred and Balanced. I will be explaining how reads and writes can be configured in these modes.

Unity Director handles data for mission critical applications that demand continuous high availability (HA), data location identification, session management, and data synchronization. It simplifies multiple Teradata Database system management tasks including routing users to the data location, rerouting users during an outage, and synchronizing database changes across Teradata Database systems. Unity Director integrates with Unity Ecosystem Manager to enable administrators to view system and table health, receive warning and critical alerts, and view analytics and statistics about data operations. As a bulk load option, Unity Director can utilize Unity Loader to selectively route large data loads from a client to Teradata systems without additional administrator operations.

In this article, I will be showing you how to establish Unity Director 14.00 routing rules which will enable you to efficiently load balance reports across multiple managed Teradata systems.
