Hi Juan Carlos, I can tell you a disvantage. Under win2003 you are not able to do a RMAN backup on a shared resource mapped as a network drive, i.e. if you want to backup 8with RMAN) to f:\ where f: is a network mapped drive you can't; you can however succedd using unc names or \\ip_address\resource This behaviour has been confirmed by Oracle Support (I opende a TAr for this). Under win2000 all works well. This for Oracle 9.2.X Giovanni -- ---------------------------------------- Giovanni Cuccu Sw Engineer@xxxxxxxxxxx Dianoema S.p.A.
