SYSTEM REMOVE Command | unityadmin | Teradata Unity - SYSTEM REMOVE - Continuous Availability - Teradata Unity

Purpose

Removes a Teradata Database system from the Unity-managed configuration.

Parameters

tdpid

Unique identifier (TDPID) of a Teradata Database system.

Usage Considerations

• After you remove a Teradata Database system, the system becomes unavailable to Unity for Read or Write requests.
• The TDPID that you specify must be valid within Unity. The TDPID must previously be added to Unity.
• The TDPID cannot be referenced in routing rules. To successfully run this command, first remove all references to the Teradata Database system from the routing rules.
• The Teradata Database system must be in one of the following states:
  • Disconnected
  • Unrecoverable

Example

The following scenario includes two Active systems, bltor and fast. The example first runs SYSTEM DEACTIVATE to deactivate the system bltor.

SYSTEM DEACTIVATE bltor;
