Re: RMAN datafile allocation to channels

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
