Teradata utilities and software programs support Teradata Database access in mainframe environments. These utilities and programs run under the operating system of the client and provide the functionality for a user to access the database system.


The Teradata Mainframe Interface enables communication between a mainframe client and a Teradata Database server using a channel with either a parallel or serial I/O interface. In the case of the Extended Channel Solution (ECS), the Teradata Mainframe Interface uses either a channel plus TCP/IP, or TCP/IP instead of a channel.

The ECS interface includes:

  • The TCHN software on the TPA node, which manages channel devices and communicates with Teradata Database
  • The APSV software on the ECS node, which encapsulates channel write blocks and sends them to the Teradata system via TCP/IP
  • The Teradata Channel Interface hardware and the driver may be located on a TPA node or on the Extended Channel Solution (ECS) node. The ECS node provides the following benefits:

  • Reduces exposure to Teradata outages induced by adapter faults
  • Enables improved mainframe connectivity to a greater number of nodes within the Teradata Database system
  • Creates more options for users connecting Teradata Database to a mainframe
  • Current platforms can be connected with the PEFA—PCI Bus FICON Host Channel Adapter.
