hi all,
for max performance - transaction can commit as long as redo entries are written to redolog on primary site. redo data are written to standby site asynchronously.
q1) if the primary site connection to the standby site fail, will the unsync redo logs be sync over once the connection is established ?
for max availability - transaction can commit as long as redo entries are written to redolog on primary site + 1 of the standbysite. if the primary site connection to the standby site fail, it will behave like max performance. once the connection is re-established, it will revert back to max availability again.
q2) if the primary site connection to the standby site fail, will the unsync redo logs be sync over once the connection is established ?
q3) In that case, what is the actual difference between the 2 mode above?
