It is my understanding that the common implementation of copying an Oracle database on an EMC using BCVs is this;

1. put the source database in BEGIN BACKUP mode for all the tablespaces,
2. break the mirror,
3. put tablespaces in END BACKUP mode
4. recover on target, or backup the files.

Question:
Why is it necessary to put the database in 'hot backup' mode when splitting a BCV? If it is just like splitting a mirror, why do you need the database in hot backup mode at all? Wouldn't it be the same as losing one side of a mirrored pair? When that happens, no extra processing is needed.
