I have worked with a Ora 10g, RMAN and Tivoli on Linux a few years ago.   We had so frequent hangups (error message buried somewhere and RMAN just sat there and did nothing) that I created a DB metric to detect that situation. The solution then was to manually kill RMAN. :-( That's of course not a solution to your problem but might be an indication that this kind of integration does not work too well although it sounds great on paper. Does anybody else have experience with that combination?

Kind regards
