Trying to set up ODBC connection

I've been trying to set up the ODBC connection for Teradata while using the program Advanced Query Tool. I've already downloaded the latest driver and installed it on the computer. When I go to add a new system data source and click on teradata, it gives me the following error message: "Unknown error occurred in terasso library."Then it pulls up the window that allows me to enter information such as name, description, Teradata Server Info, Default database, Username, Password, and Account String. After entering this information, I get another error message: "Unable to write Accountstring into private profile."Does anyone have any ideas?

What TTU are you using? Before installing the ODBC driver, there are other dependencies such as TDICU and TeraGSS packages. These need to be installed first before installing ODBC driver.

Hi,I have the same problem. The newest ODBC driver (6/28/2006 11:25:48 AM) can be downloaded at ""But where I can download the "Teradata Generic Security Services" (TeraGSS) and the "Shared common components for Internationalization for Teradata" (tdicu)?Best Regards,Uwe Posselt.

The driver download file is actually a self-extracting "bundle" that includes the appropriate TeraGSS and TDICU as well as the driver itself.

Ok, thank you for the information.The package contains TeraGSS, TDICU and TDODBC I've got a newer TeraGSS by a NCR supporter.

I'm facing the same problem it says "Unknown error occurred in terasso library".I uninstalled ODBC from my laptop and installed latest version and GSS and ICU bundled with it but still my problem is not resolved.Can anybody help me in fixing this issue.Thanks in Advance,Munir

Have you installed the drivers in the correct order (1. GSS, 2. ICU, 3. ODBC)Which windows version are you using?

SocioProgrammer 1 post Joined 08/05

When I eventually solved the error, I think I remember it having to do with permissions. I didn't have the permission to access a connection that someone else had set up, I think. Look at your permissions.

I am having the same problem and nothing has worked. I have uninstalled all of the Teradata software including the terasso.dll file. Rebooted the pc (more times than I can count) and have tried to install the drivers in the order suggested (GSS, ICU, ODBC) and still get the terasso error. No one else in my workgroup is having this problem and we are all running Windows XP. Help!

did you uninstall ODBC, GSS and ICU before reinstalling them?1) Uninstall ODBC, GSS, ICU2) Install them in correct sequence -> GSS -> ICU -> ODBC

Some uninstall did not work properly. Search your hard drive for multiple copies of the terasso.dll file and remove old ones manually.

Update for TD13
I had the same problem going from TD12 to TD13. (Cannot find terasso library and cli utilities giving a teragss error)
This problem was caused by TeraGSS not being installed properly.
A easy way to check if it's the cause of your problem is to run the command "tdgssversion" from the directory:c:\Program Files\NCR\Teradata GSS
"nt-i386\xx.xx.xx.xx" (the TeraGSS version just installed).
You should see an asterix after the new version number: xx.xx.xx.xx *.

If you don't see any * or the * is paired with an old version then the problem is there.
Execute the following under the above new TeraGSS directory:
"tdgssversion -switch xx.xx.xx.xx" (the new version) or
Usually you will heard a loud beep at the cmnd completion.
Rerun tdgssversion to verify the * has been switched to the current version. If yes then the problem is resolve.

You may receive the error message: lclient symbolic link could not be deleted.
In this case you need to uninstall (start/ctrl panel/ remove program) all teradata gss program and reinstall the new one.
In my case I had to install two new version of the same release (ex and to get away with the Lclient symbolic link error.
Also make sure your user have write permission on those directories.

Try using the latest TDICU. package. The issue observed was fixed in this particular version.

It seems that is the latest available (5/4/2011). That gets me thru the ICU install but gives me that same error when trying to install the ODBC itself.

I have installed the teradata ODBC driver along with the teraGSS and tdicu. I can go to the step where I should now configure my ODBC driver. I am completely new to deal with teradata and am trying to figure out whats the best way to test my connection. Is the DNS name of the terdata server enough to be able to connect to the database? Dont I need like any port number or source name to plug into teh configuration?Alos I noticed that the configure window does not give me a button to test connection...any ideas?


I will highly appreciate any input around this.

I am sorry - I forgot to mention that I have installed the ODBC driver on a 64-bit windows server.

Was anyone successfull in creating a valid connection via the ODBC connection? What settings did you use? How would you reommend setting up the connection?

Help, I am trying to install on a Windows 2008 Server 64 bit. I have downloaded the 64 bit driver but I am still getting the error: 2738 Could not access VBScript run time for custom action.

You might be getting this error on a Windows 2008 64-bit Server because the vbscript runtime library is not registered correctly. Try registering the library using the following commands from command prompt.

c:\>c:\windows\system32\regsvr32.exe c:\windows\system32\scrrun.dll

c:\>c:\windows\syswow64\regsvr32.exe c:\windows\syswow64\scrrun.dll

Try installing the ODBC Driver package after this.

We are upgrading our database from V12 to V13.10.  In preparation for our upgrade, we have upgraded our TTU components to 13.10.  We have also installed Viewpoint to replace Teradata Manager, TDWM, ect.

It looks like the effort to upgrade desktop ODBC drivers from 12 to 13.10 across our enterprise will not be complete when the database is upgraded to V13.10.

The documented Teradata Roadmap shows TTU 12 is compatible with database releases 1  forward and 2 backwards.

I don't have a test system with the database upgraded to V13.10 yet to test if ODBC Driver 12 works with database V13.10.  I'm trying to plan for the effort ahead.

I know it's not documented or supported, but does anyone currently have an 12 ODBC driver accessing a V13.10 database successfully?
