I have to do a lot of database refreshes from production / standby to dev systems, they are on different boxes and are using different filesystems, which in turn are of different size. I'm looking for a way of automating the calculation of space requirements, mapping filesystems etc. I've only been able to find this online tool www.tiplib.com/tools/oracle/rename-datafiles which does the job partially, but I'm looking for a solution that automates this task completely. Any ideas? Thank you.
