You can *never* backup any Oracle database file which is "hot" without first invoking some mechanism that allows Oracle subsequently to fix up the internal inconsistencies that *always* arise when you hot copy files.

For data files, that's the 'alter tablespace begin backup' command. And for control files it's the 'alter database backup controlfile to something' command.

OCOPY does *not* do this particular trick -it simply allows you to copy files which NT otherwise would see as locked (and thus prevent you doing the copy).
