System.Data.OracleClient requires Oracle client software version 8.1.7 or greater
Posted on 2014-10-14
I have a C# application which updating records in Oracle 11g database. It was working fine on another testing environment which running WinXP. After I copied to another XP machine, I got error "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater". The old machine is running Oracle9 and the new one is running Oracle10. In the new Xp machine I can use sqlplus to log into the database.
I saw there are solutions for folder permission online. I gave Authenticated user all the permission needed. but still got the same error.
