Dick,
Opening with 'RESET LOGS' should only be needed after an incomplete
recovery.
At this point you would need to make a *cold* backup.
I'm sure to catch flames for that last statement, but I don't care, I'll
stand my ground.

Subject: Re[2]: What is the point to use "alter database rename file"
One other point, when recreating the control file you many times have to
do a
resetlogs at the end which invalidates all of your previous backups. I
for one
hate to loose any avenue to a recovery if needed. Actually I hate
anything that
forces me to rebuild the control file(s), you can loose too much history
that
way. Now I will admit it would be one great enhancement to the command if
the
kernel would then move the datafile for you. Of course it would be good
if drop
tablespace also cleaned up after itself, but then that's a 9i feature,
only if
you have a storage vendor who supports Oracle's OMF API.

well, I can think of one off the top of my head -- your way the
database has to be shutdown.
using alter database rename file you can just take the tablespace that
owns that datafile offline and do the work. All users who don't need
that particular tablespace are not affected.
