Force a Checkpoint

Force a Checkpoint:

|-- -c--+-------+-----------------------------------------------|
        '-fuzzy-'

Element	Purpose	Key Considerations
-c	Forces a checkpoint that flushes the buffers to disk.	Additional Information: You can use the -c option to force a sync checkpoint if the most recent checkpoint record in the logical log was preventing the logical-log file from being freed (status U-B-L).
fuzzy	Performs a fuzzy checkpoint.	Additional Information: Use the onmode -c fuzzy option to force a fuzzy checkpoint. Then use the onstat -b command to check the number of modified (dirty) buffers. The modified buffers that are still in the buffer cache contain fuzzy transactions.
