Purpose

Changes the state of all tables in the specified database from Active to Standby.

Syntax

DATABASE DEMOTE{<database> [ON tdpid[,tdpid]]} [REASON 'reason'];

Parameters

database
Name of database holding tables currently in Unity Data Dictionary.
tdpid
Unique identifier (TDPID) of a Teradata Database system.
reason
Description of why objects on the database need to be demoted.

Usage Considerations

If a system is not specified when running this command, it sets all tables in the database to Standby on ALL systems, which is not usually correct. Specify a system to make the tables Standby only on one system.

The following example shows how to demote a Teradata Database system with TDPID fast in Standby state.
