Dear Readers,

In this article, we will learn about Tset.

What is TSET ?

  • TSET stands for Teradata System Emulation Tool.
  • It is a tool that is used to collect a set of support files that help in troubleshooting issues.
  • It allows you to emulate a target system by capturing system-level environmental cost information, table-level information like dynamic AMP sample statistics and optimizer-relevant DBS control information from that environment and storing it in the relational tables of systemfe database.
  • This feature produces a query plan and not the performance of the system.

How to establish connection to Teradata Database from TSET ?

It can be done using :

1.Teradata Open Database Connectivity (ODBC)

  • Define a data source for each Teradata database prior to connecting.

2.Teradata Call Level Interface Version 2 (CLI v2)

  • Define an IP address and provide name of the Teradata database to use in “hosts” files located at system32/drivers/etc.

Where to download TSET from ?

For a specific version of TTU suite of windows OS, there are 3 packages available :

  1. DatabaseManagement
  2. TapeStorageManagement
  3. TeradataToolsAndUtilities

TSET is a part of DatabaseManagement suite and not in TeradataToolsAndUtilities suite.

  6. Click submit

Defining data source in TSET

  • After the TSET is installed, open TSET application.
  • To define a connection, first we need to choose the connectivity type from Tools i.e ODBC or CLIv2

1.Define ODBC data source :

To do so, click on TSET- >Tools -> Options -> connectivity ->ODBC -> Ok.

  • To define data source, go to Tools -> Define Data Source -> Add -> Teradata Database ODBC Driver -> Finish


When you click on Finish, a new window pops up to add data source information as shown below :

Enter a valid data source name under “Data Source” and a valid Name or IP address under “Teradata Server Info”.

Then enter username and password(not mandatory) and click on OK.

After you click on Ok, you should be able to the data source defined under User DSN.

Then click Ok.

2.Define CLIv2 data source

Add the database name and IP address in hosts file under the directory  “C:\Windows\System32\drivers\etc\hosts.

Open the file and enter the IP address followed by databasename with suffix cop1 and save the file as shown below :

Verify the connection before connecting in TSET using ping command.

Start -> cmd -> ping databasename

Example : ping localhostcop1

To make the connection :

TSET -> Connect -> select the data source you would like to connect to -> Ok

  • For TSET tool, we have two windows :
  1. Main Window : when we open TSET initially, we see this window.

  1. Import window : When we use the import option, we see this window.
