RE: RMAN backup with MULTIPLE CHANNELS ......
Babu - We allocated multiple channels on an RMAN disk backup and the backup time was reduced. I would suggest you try to figure out where your bottleneck is. Are you writing to multiple tapes? Actually, RMAN has several features to keep the tape streaming, you may want to look at these. If your tape isn't streaming, you might get more throughput from a single tape drive than you are now.

RE: RMAN backup with MULTIPLE CHANNELS ......
Dennis, Thanks for your reply. Iam taking tape backup with 3 channels as we have multiple tape drives. I don't know where the bottleneck is. In the RMAN output I see it is using all the three channels simultaneously with 10 datafiles per channel. But Iam not getting the throuput. It is taking the same amount of time as it used to take for single channel. I don't know where to look, and don't know how to fix the problem and take advantage of multiple channels. -- Babu -Original Message- Sent: Thursday, February 20, 2003 9:39 AM To: Multiple recipients of list ORACLE-L Babu - We allocated multiple channels on an RMAN disk backup and the backup time was reduced.

RE: RMAN backup with MULTIPLE CHANNELS ......
One possibility is that the backup job is already maxing out the network connection between the client system and the Veritas NetBackup master server and/or media server. If you have a 10megabit network and LTO drives, the network will never be able to keep the tapes streaming. Adding 3 channels won't help if your network can't keep up. I'm speculating here, as you don't really supply enough info about your environment.

RE: RMAN backup with MULTIPLE CHANNELS ......
Just be sure and post it to the list. There are folks here with more NBU/RMAN experience than I. Network between database server, master server and media server. 10Megabit, 100 Megabit, Gigabit? Concurrent backup jobs? # of Tape drives dedicated to this backup? Type of drive? LTO, DLT, Super DLT? This question is better phrased as: What is the streaming capacity of the drives involved in the backup? There are more questions, but this is a start.
