Optional specification of Teradata FastLoad utility default values

When running Teradata FastLoad in interactive mode, the terminal keyboard functions as the standard input device and the display screen is the standard output/error device.

When running Teradata FastLoad in batch mode, a data set or file name must be specified for each of these functions. The method of doing this varies, depending on the configuration of your client system:

  • On network‑attached client systems, use the standard redirection mechanism (recommended approach) to specify the Teradata FastLoad script files when invoking the utility. Teradata FastLoad script files can also be piped to Teradata FastLoad when invoking the utility.
  • On mainframe‑attached client systems, use standard z/OS JCL control commands to allocate and create the Teradata FastLoad data sets or files before invoking the utility.
