odbc dsn installation

Dear all,

This might seem as a trivial question, but I have a machine with Windows XP SP3 installed. I want to connect to an Oracle database located on an intranet server through odbc. The Microsoft driver that is on the machine does not have a field to specify TSN service name. I came across documentation on the web (an Oracle document) which shows an Oracle DSN which contains a field for TSN service name and other parameters.

The question: Where do I get this driver, and how do I install it?

    If you are trying to connect 11g database, please use the below link to download the Oracle Client

    If you want to install 32 bit driver, choose platform or language as "Microsoft Windows 32 bit",  download and install the file 3 of 6 -

    If you want to install 64 bit driver,  choose platform or language as "Microsoft Winodws X64 (64-bit) "  download and install the file 4 of 7 -

    Please set TNS_ADMIN to see the list of databases available in TSN.

    Thanks and regards
