Hello,
It is not a problem at all in Oracle, the client works fine with any server (32-bit or 64-bit or big-endian or little-endian, whatever). Are you using ODP.NET? If not then please try using ODP.NET. Please do remember to
download[
^] the correct version of ODP.NET that matches with the version of your database eg. 10.2.0.2.21, 10.2.0.2.20 etc.
Regards,
