Can any one please tell me whats the difference between channel and parallelism in RMAN ? Read through the docs however still not clear.

What is the Oracle recommendation for RMAN channel allocation ? I have read some were that RMAN channel allocation must be 4 times of the Server CPU -1. Say for example if there are 2 cpu in the server, then the channel allocation would be 4 * 2 -1 = 7 ?

Channels are the way to define parallelim with RMAN; so they are the same thing.
