The "DBWR checkpoints" statistic (v$sysstat) indicates the number of checkpoint requests completed.
The ckeckpoint process was optional in Oracle 7 (set CHECKPOINT_PROCESS=TRUE) and could be enabled to speed-up checkpointing on databases with a large number of files. Starting with Oracle 8i, the checkpoint process is automatically started with the other Oracle processes at instance startup.
