Teradata Tools and Utilities
On z/OS platform, Teradata FastExport has the following two variants:
  • Teradata Director Program (TDP)
  • Mainframe Cloud-Network Connectivity (Gateway)
The external name for the Gateway variant is 'Mainframe Cloud-Network Connectivity'.

The TDP variant of FastExport uses the channel-attached CLI to interface with the Analytics Database, which requires a channel connection.

The Gateway variant of FastExport uses the network-attached CLIv2 to interface with the Analytics Database, which uses the Database Gateway software.

The following table shows differences between the two variants:

For TDP Variant Gateway Variant
Access to Analytics Database on a cloud No with direct channel connection Yes
Channel connection Yes, required No
CLIv2 Uses channel-attached CLI Uses network-attached CLI
CLIv2 error codes Uses channel-attached CLI error codes Uses network-attached CLIv2 error codes
Connection string Not supported Supported
Interface with Gateway software No Yes
Longer session connection time No Possibly
<hlq>.ETC.IPNODES member file Not required Yes, required
Display of variant in FastExport log CLIv2 : <Version> (TDP) CLIv2 : <Version> (GTW)
Supported SQL Engine versions All supported versions 17.10.00.00 or later

17.05.05.03 or later

16.20.53.31 or later

The Gateway variant of FastExport can take a longer time to connect sessions, as there is more overhead between the network-attached CLIv2 and the Database Gateway software for authentication and encryption. This overhead does not exist in the TDP variant of FastExport.

The Gateway variant of FastExport requires COP entries in the <hlq>.ETC.IPNODES member file. The entries must define the IP address and COP alias name for each database node. <hlq> is the site defined high level qualifier data set name. The TDP variant does not use the <hlq>.ETC.IPNODES member file.
