Hi
as I understand things when a change occurs something writes the change
from the database buffer cache to the redo log buffer. Then upon commit
(I
suppose its) LGWR copies these changes from the redo log buffer into the
redo
log files. But does it also write the rollback segment relevant to the
transaction too?
If so, I'm not sure I see why it might be needed?
thanks
See Ya
