Did u find out why the cold backup was kicked off what is the reason? I suspect that OS couldn't copy some of your datafiles.May be this is a I/O error.Recovery is little bit tricky since the database is in Noarchive mode.It is glad that u had a cold backup.Otherwise in this scenario u could have lost some of information while recovering from that datafile.
