I was asked whether it would be possible to install the "RMAN binaries" on a host (I'm not quite sure what this means, since RMAN was installed with Database 10g... are recovery catalog files typically called RMAN binaries?), and to install a central catalog as a repository for multiple databases on multiple servers.

I'd greatly appreciate if someone can explain what is meant by the first part ("RMAN binaries"), and give me a pointer to information or examples of the second part.

Thanks!
