Dear List,
I have changed my RMAN backup script to use multiple channels(3) as we have
plenty of tape drives. It is taking the same amount of time as it used to
with single channel. The DB size is 120gig. The output indicates it is using
three channels while backing up. Anyone has any idea why
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

Look for something like channels-per-tapedrive on the backup server configuration. You
have to be above this figure to use multiple tape drives.
