Configuration Maps

Although the Configuration and Reconfiguration utilities are functionally independent, normally they are used together to change the contents of working areas, called configuration maps, in the node.

A configuration map:

  • Stores the identification and status of each vproc in the Teradata Database
  • Identifies the AMPs that constitute each AMP cluster
  • Identifies each PE and its associated host
  • The node contains these configuration maps:

  • The current configuration map, which describes the current arrangement and status of vprocs in the system
  • The new configuration map, which includes changes and additions to the configuration
  • If you want to list or show information about or to delete a vproc, first you must have added it to the applicable (new or current) configuration map.

    If you want to add a vproc to the new configuration map, you must have defined the AMP or PE through the use of the PUT utility.

    These component types constitute a Teradata Database configuration:

  • Hosts (or clients)
  • PEs
  • AMPs
  • The following sections describe these components.
