ORA-00297: must specify RECOVER DATAFILE LIST before RECOVER DATAFILE START

What triggered the Error:

The RECOVER DATAFILE START command was issued, but no RECOVER DATAFILE LIST commands had been issued. This only happens when doing recovery with Recovery Manager, and is an internal error in Recovery Manager, because Recovery Manager should always issue RECOVER DATAFILE LIST before RECOVER DATAFILE START.

What should we do to fix it:
