Purpose

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

Syntax

SYSTEM REMOVE tdpid ;

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;
unityadmin> Operation Number : 6

User             : admin
User Name        : Main Administration User

Status      : Finished (1)
Finish Time : 10/19 12:51:07
