Suppose that each database page contained the LSN of the commit record of the last transaction that has committed and written a database item in the page, and suppose that the system uses the policy that it does not flush the page from the cache until the LSN of the oldest record in the log buffer is greater than the LSN of the page. Will the write-ahead policy be enforced?
What will be an ideal response?
No. An item updated by an uncommitted transaction might be contained in the page.
