Yep its me answering a question for you for
a change - I was able to bounce your question off of Dinis (our RMAN
guru) and he said: ( Yeah I could have pretended that I knew
the answer but I don't think you would have fallen for that!)
Channels are streams. Basically when you
have multiple channels (lets say 4 channel) you can write to take or disk with 4
streams at the same time, which means that you will be able to backup more
datafiles concurrently. No channels are not related to CPU or destinations. Yes
it makes sense that you allocate more channels because it will shorten you
backup time but then again the more channels you use the more resources you will
be using on the server that you are backing up the database. I hope this answers
your question but if not please let me know.
P.S. Each channel
will correspond to a session in the database that is being backed
up.
