Hello Dear,
I am using VS 2008 with frame work 2.0. On my development machine I am using Oracle 9 as database. When I deploy my application where Oracle 9 is installed it works properly. but it gives error on oracle8 installed machine as follow.
"System.Data.OracleClient requires Oracle client software version 8.1.7 or greater in vb.net"

Any one can help with out installing Oracle9 I can get rid from this error.
