ORA-12154 when using EF Oracle Provider

When using EFOracleProvider, ORA-12154 might occur if there are 2 Oracle clients installed on your machine. The problem is that EFOracleProvider is looking for for tnsnames.ora in client_2 folder instead of client_1. The workaround is copy tnsnames.ora to client_2 folder as well.
