I have installed Oracle8 and I try to connect it with Asp.net2005 but while connecting with the control SqldataSource it genertaed the following error :- System.Data.OracleClient requires Oracle Client s/w version 8.1.7 or later.

I have tried the above procedure with oracle10g.
Is there any solution for it.

Sounds as if there may be a problem with versioning. It would be helpful if you would send the information from the execution of the following command from PL/SQL:
SELECT banner
FROM v$version;
 This is just a suggestiion.
