Here the the answer to my own question. This is the response from Oracle
support about how datafiles are allocated to channels.
The manual approach means explicitly specifying which datafiles go with
which channels. I need to look at this further, because what happens when
you add a datafile and fo

was very flaky, after 8.0.5.1 is became a very usable product. I have been
using it since I started with Oracle, 8.0.4. I am now on 8.0.6.3. It is
very stable.

Actually we are on 8.0.5.1. What are the differences in rman between these
versions?

Keith - We were using 2 channels writing to disk and RMAN was putting almost
an equal amount of data to each channel. For space purposes we needed to put
more data to one disk. The only way I found to do this was to create 2
channels to the disk I needed to write the most data. That works fine, but
My condolences on 8.0.5, you should patch to 8.0.5.1 for better a much

I think that every channel is used for each datafile. When one datafile has
been completely backed up the channels are used for the next. This is
empiracal thought, what I have observed. I have 2 channels goin
Does anyone know how RMAN decides which data files get backed up by which
channels. I'm backing up to disk and have 4 channels, each to a separate
disk drive. The data files seem to get assigned to channels at random. Also,
this is a version 8.0.5 database (U).
