Hi All
If SQL Server does a checkpoint every time the instance is stopped (Cleanly).
Why is it that when SQL is started up again, I see:
xxxtransactions rolled back in database....
xxxtransactions rolled forward in database...
Am I missing something here?
Thanks

A shutdown doesn't necessarily cleanly shut all DBs down, and a checkpoint doesn't mean no recovery necessary, consider uncommitted transactions whose changes get written to disk as part of the checkpoint.
