Just to go a little further into the 'why'... When a tablespace is either put into backup mode or taken out of backup mode, a redo entry that records this event is made in the online redolog. When you copy off the datafiles, SYSTEM.DBF records that you put these tablespaces in hot backup mode. When you deleted all the files, including the online redolog, the redo vectors that record the fact that the tablespaces came out of hot backup mode are now not available. When the database is opened now with RESETLOGS, all datafiles need to come up to the maximum SCN amongst themselves - details of which is present only in the first archive logs generated *after* the backup completed on the source system. I.e. you *SHOULD* have altered system to switch logfile, and preserved the contents of the last online redolog. You will then have to apply at least this one archivelog with a CANCEL based recovery before opening the database.
