LGWR 要執行寫動作時
會等待微秒 (應該不超過一秒)
Where do you see that wait for a microsecond rule?
There used to be a Metalink thread 194107.999, where the analyst quotes an Oracle kernel developer saying that LGWR waits 10 centiseconds after it's posted by the first commit, to see if there's another commit request coming in. If yes, they're combined into one.
But Jonathan Lewis questioned that claim saying it would be way too long. Now that thread is off from Metalink.
