Teradata Database

This chapter provides information on using the DBS Control and Ferret utilities to tune and troubleshoot Teradata VS. For more information on these utilities, see Utilities.

The Teradata Viewpoint Virtual Storage collector and TVS Monitor portlet allow you to collect and view statistics on data temperature and storage grade of cylinders allocated in Teradata VS. Statistics reflect current relationships between data temperature and storage grade, and historical trends in the management of storage grades based on data temperature. Temperature and grade metrics can help assess storage requirements for data, as well as aid in fine tuning the balance between disk performance and data-access demands. For more information about the TVS Monitor portlet, see Teradata Viewpoint User Guide.

Teradata Virtual Allocation Manager (tvam) is a tool for managing storage optimization and data migration aspects of Teradata VS. It should be used only under the direction of Teradata Support Center personnel. Tvam documentation includes a man page and online help.
