Oracle.DataAccess ExecuteNonQuery returns -1 on MERGE statements, and ASP.Net deployment

Hi everyone,

First question: 
Since the migration from System.Data.OracleClient (deprecated) to Oracle.DataAccess.Client (recommended) of my connection class to Oracle Database in .Net 4.0, the ExecuteNonQuery method returns -1 on MERGE statements. The rows are updated or inserted well though.

Is it possible to check the request return, in addition to the ErrCode checking?

Seconde question: 
I had to download the ODP.Net (or ODAC?) provider to reference Oracle.DataAccess.Client DLL in my project on my developper machine. 
When I will deploy my ASP.Net sites on the customers platforms (Oracle 9i, 10g, 11g, InstantClient 10g... x86, x64...), would I have to install ODP on this different platform? Or would the DataAccess DLL be compatible?

Howdy, Stranger!
