No, I can't say I ever heard "ORACLE BINARIES". I assume by that you mean Oracle Database's binary commands, such as emctl and netca, correct? It would then logically follow that by "RMAN BINARIES" you mean the rman command itself; is that a correct assumption? And if so, why would someone ask to have the "RMAN BINARIES" copied onto a host on which Oracle Database 10g has already been installed, since that installation implies that rman already exists there?
