Re: RMAN channel explanation

A connection between RMAN and the target database. Each allocated channel starts a new Oracle server session; the session then performs backup, restore, and recovery operations. The type of channel determines whether the Oracle server process will attempt to read or write and whether it will work through a third-party media manager. If the channel is of type:

DISK, the server process reads backups from or write backups to disk sbt, the server process reads backups from or write backups to a third-party media manager
Channels are always able to read and write datafiles to and from disk, no matter what their type.

RMAN parameters that allow you to control I/O for backups and copies created by a channel.
