It is possible to have consistent backup without altering the
tablespaces in to backup mode, using a special type of split known as
consistent BCV splits. This method is supported by EMC for Oracle
database backups and mentioned in various documents. You need powerpath
or ECA for the consistent split to work. I/O to that device is frozen
while the split is underway.
Even then, I would be inclined to alter the tablespaces to backup mode
and then split.
Thanks Riayj
