How to set the WHOLE Database in backup mode

Well we know the command "alter tablespace <tralala> begin backup", but if there are a dozen of tablespaces, and one has to make a hot Snapshot of the DB files, then I wonder if having to use this command a dozen of times (for each tablespace separately) will garantee that all tablespaces are in sync when the last of them is set in backup mode.

So is there any other command to set the DB as a whole in the backup mode?

Thanks
