Teradata 13 Express Install

For those of you wanting to install Teradata on your own PC, Teradata supplies a free "Express" version.  Go to this site to request to download it: http://www.teradata.com/downloadcenter/

You will have to register with Teradata and then request the Teradata Express by clicking the "Order Now" link in the "Teradata Express — Teradata Software for Evaluation and Development" section. You'll have to look carefully for it.

I installed version 13 on my home PC which has Windows Vista Home Premium for the OS.  I had several problems which I'll detail here in case you run into these, too.

I used the "silent" install method at first.  Be sure to read ALL the text with each installation step; don't assume the "usual" steps of just accepting defaults and going on.  The silent install method is the default and it will merrily try to install everything, but won't give you any error messages if anything fails.  So at the end, you will be told that the installation has completed, but it may not have been successful.

Thinking I had a successful installation, I followed the instructions to verify that from the user guide.  From the "Teradata Service Control" I clicked the "Start Teradata" menu item.  When it completed, I was told "Teradata is Running" in the lower left corner.  When I clicked the "File" menu to execute "Session info", it was grayed out.

HOSTS file edited
Reading the installation documentation, I found that the HOSTS file is modified by Teradata.  I looked at my HOSTS file (which is a custom one that blocks Internet advertisements and other unwanted sites) and found that the Teradata install program had botched the addition of the following line:
127.0.0.1  localtdcop1

Make sure that line is on a line all by itself.  Also make sure that "localtdcop1" has not been added to the end of every line in the HOSTS file that begins with 127.0.0.1!

ODBC Driver
I also discovered that the Teradata ODBC driver had not been installed.  I tried to reinstall it, this time not using the "silent" install method.  This time I got an error message: "Error 2738.Could not access VBScript runtime for custom action."

The resolution for this error is to make sure VBScript is registered.  Do this by following these steps:

1. Run Command Prompt as administrator:



1. Start Menu -> All Programs -> Accessories
2. Right click on Command Prompt and select Run as administrator



2. Run the following command:



• If you are using 32-bit version of Windows:



• Type cd %windir%\system32 into the Command Prompt and hit Enter



• If you are using 64-bit version of Windows:



• Type cd %windir%\syswow64 into the Command Prompt and hit Enter



3. Type regsvr32 vbscript.dll into the Command Prompt and hit Enter.

Now you will be able to install the Teradata ODBC driver.

Firewall
But I'm still having problems.  Even though I can now start Teradata and the "Session Info" menu option is available, clicking it starts a dialog box that tells me to  wait while sessions are retrieved.  After 12 minutes, I cancelled it.

I opened "Teradata Administrator" and tried to connect as user tdadmin (created by default).  I got the error message "ODBC HY000: WSA E HostUnreach: The Teradata server can't currently be reached over this network."

The fix for this was to turn off all firewalls.  I had both the Windows Firewall and Avast's firewall running.  Since my PC is behind a cable router that has its own firewall, turning both of these off poses no threat.

SQL Assistant
I found that the Teradata SQL Assistant did not get installed.  Using the "not silent" install mode, I discovered that this requires the .NET Framework version 2, SP 2.  I tried to install this again from the "Other Software" install option, choosing the "not silent" install mode, and discovered that this would not install on Vista.  I was unable to find a version of .NET Framework version 2 that would install on Vista.

There is a "work around" to this.  Teradata has a Java version of SQL Assistant that will work on Vista.  You need to go to the Teradata download site to get it.  In my case, for Vista on 32-bit platform, I went to http://downloads.teradata.com/download/tools/sql-assistant-java-edition-13-01-for-windows-32-bit
