openlink.sh and openlink.csh odbc.ini odbcinst.ini openlink.sh and openlink.csh oplrqb.ini *www_sv.ini* Windows drivers do not contain the Multi-Tier client files. Client environment variables appear on the Environment or Advanced tab of the System utility. The odbc.ini and odbcinst.ini files are replaced by the HKEY LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI and HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI sections in the registry. Windows server installations retain the oplrqb.ini and www_sv.ini files.
