Setting Up the HOSTS File for Teradata Installations on Windows

If you are using a Teradata database, you need to set the TDPID parameter on the machine where the Informatica Server is installed by adding an entry in the HOSTS file.

To set up the HOSTS file for Teradata installations

1. On the machine where the Informatica Server is installed, go to the \<SystemRoot>\system32\drivers\etc directory and open the HOSTS file.
2. In the HOSTS file, enter a line in the following format:

   <IP address of remote server> <remote server> <remote server>COP<n>

   For example:

   172.20.176.208 tdatsvr tdatsvrCOP1

   where tdatsvrCOP1 is the alias for the remote server. The alias must begin with an alphabetic string and end with the COP n suffix, where n is a number between 1 and the total number of applications processors that are associated with the Teradata communications processor.

3. Save the HOSTS file.

For more information about setting the TDPID parameter, see the Teradata documentation.
