Nah. Way off. RMAN does backup and recovery. Oracle Streams or Data Guard does transfer of SQL or redo logs across to other instances. Different beasts entirely. Therefore...

Irrelevant. The premis doesn't compute, therefore the comparison is moot.

Sounds a bit feeble for robust replication, actually.

Wouldn't have a clue. But I'd recommend you learn the difference between RMAN, Data Guard and Streams. Just for starters.

PS. A post does NOT need to be posted to every conceivable newsgroup to warrant a reply. Please post these sorts of questions to .oracle.server, and leave it at that. Otherwise, you become a spammer, and deserving of abuse and contempt. I have trimmed your massive cross-post accordingly.
