Re: rman question(allocating channels)

[Ed Lewis]

Joe,     I have the same situation. I my case I used 2 channels, and so around a 25-30% decrease in the backup time for a 30gb database.    Once I increased it to 3 channels the payback was minimal. It also became very cpu intensive, so I kept the setting at 2. ----- Original Message ----- From: JOE TESTA To: Multiple recipients of list ORACLE-L Sent: Wednesday, August 28, 2002 8:38 AM Subject: rman question(allocating channels) I've tried to find this in the docs to no avail.   If I'm writing out an RMAN backup to one disk(yes this is not ideal), then does it make sense to allocate multiple channels?   Are multiple channels related to CPUs or to destinations?   thanks, joe
