My qustion is this. As I understand it the redo
log buffers are flushed when they fill or when a
commit is issued. If the machine fails and
restarts how does Oracle ensure that DBWR hasn't
written changed datafile blocks to their
respective datafiles? Does DBWR somehow ignore
updated blocks that haven't had their log updates
externalised or is there some other process at
work?
