I will add.... I've seen times that Windows will lock files and it dosen't
matter what you do (including killing the service) the only way to get that
lock released is to reboot the box. THAT is a pain.

failover to previous backup
Hi Bill,
Taking a tablespace offline on windows does not seem to remove the lock
that Oracle has on it.
When a file is open, the process has a lock (don't know the windows
technical term for the
type of lock)
Just tested this on my laptop: took 10g tablespace EXAMPLE offline, and
the handle utility
(from Sys Internals toolkit) shows that the EXAMPLE files are still open
by Oracle:

I've never restored a tablespace on Windows, but it appears that your
procedure may need to be modified a bit.
Have you tried restoring the tablespace with Oracle in mount mode?
Our resident RMAN expert (Robert Freeman) may know the answer to this.
