Oracle Integration componet

This is the first time I've tried to connect to anything other than a SQL database.  I am trying to connect to Oracle to pull RC codes.  I'm not sure what is going on, but I keep getting the error "Connection Test Fail. System.Data.OracleClient requires Oracle client software version 8.1.7 or greater."  Can someone please walk me through the steps to connect to Oracle?

Thanks,

John
