A checkpoint process (CKPT) is an Oracle background process that is responsible for recording the details of database checkpoints by making the necessary updates to the headers of the datafiles and the control files. After every three seconds, the CKPT process records information about the checkpoint position in the online redo log, in the control file. During data recovery process, only redo entries recorded after the checkpoint position are required for data recovery.
