How oracle will roll back the transaction

Nishant SanthanApr 20 2007 — edited Apr 24 2007

Hi... I am just new in Oracle and Last month I have completed my OCP, I just wanted to know if an uncommitted dirty block has been written back to data file by the Dbwriter and its changes (logs) are over written by Log writer as those block not there in database buffer, how oracle will roll back this transaction? When?

Thanks
