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 ?

Which Oracle pdf? Can you post the link to that document here ?
CKPT updates the controlfile during incremental checkpoints and all the datafile headers(with the checkpoint information) during the full checkpoints. This is required for recovery purposes.
