Current Environment:
Native System: Win7 64-bit
Toad Version: 11 32 bit
Database: Oracle 10g
===================================
Unlike Plsql developer, Toad need to download
Instantclient-basic-win32-10.2.0.4.zip
Instantclient-sqlplus-win32-10.2.0.5.zip
Two packages, and Toad (as of current version 11) only supports 32-bit clients
====================================
1. Unzip Instantclient-basic-win32-10.2.0.4.zip, instantclient-sqlplus-win32-10.2.0.5.zip two packages to the same directory, e.g. D:\Develop\oci
2. Configure Environment variables:
Tns_admin-D:\Develop\oci
Path---...; %tns_admin%
3. Start Toad to log in directly using information such as IP address, port and SID
