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 startup force?

  select

          'alter database datafile ' || '''' || f.name || '''' || ' end backup;'
  from v$datafile f, v$backup b
  where b.status = 'ACTIVE'
  and f.file# = b.file#
  /

  run the generated SQL.
