In oracle's pdf,
The Checkpoint Process (CKPT) is responsible for updating database status
information in the control files and data files whenever changes in the buffer cache
are permanently recorded in the database.

I don't understand what kind of infomation can be called database status information, Can anyone give an example ?
And why the database status information should be updated after the data was permanently recorded in the database ?

CKPT porcess updates datafile and control file headers with current SCN. That means upto that point the database is in consistent state.
