Checkpoint Monitoring in Oracle
Checkpoint Monitoring in Oracle
A Checkpoint ensures Data file consistency. It is performed by Oracle. a checkpoint occurs, when all modified buffers are written from the data buffer to disk files. Checkpoints also lead to the updating of data file headers.
If the Oracle background process CKPT is not available for your system or is not started, the Oracle log writer (LGWR) will have to perform this task. The background process CKPT is active if the init<SID>.ora parameter log_checkpoint_process is set to true .
If this parameter is set to a value larger than the size of the largest on-line redo log file, Oracle will not perform additional checkpoints in between the redo log file switches.
