Of course, there is a checkpoint, and then there is a checkpoint. :-) Crash
recovery is all about when did the checkpoint complete, not when did it
begin, correct? :-)

Then the database will say these files require media recovery. Then you, the
expert DBA that you are, will do an "alter database datafile {filename} end
backup;" followed by an "alter database open;" and all will be well. :-)
My general approach to bouncing a database that typically takes a long time
to shutdown immediate is:
1) shutdown abort
2) startup restrict
3) shutdown immediate
BTW, unless I'm mistaken, checkpoints occur automatically at the least every
3 seconds.

What happens if you have datafiles in backup mode and you try and do a
