hi,

I am migrating database to 10g and I want to organize the data.
So what is better, create various datafiles or a big file in a tablespace?

more physical devices, more better.
On a single disk, it does not matter.

On a single logical volume, it does not matter.
All the I/O does down a single channel/path
