On 8i when you do a graceful failover you copy the online redo logs
manually from production to the standby.
9i makes it even easier and it creates the online redo logs on the new
primary for you. The files for the redo logs on the old primary remain
on the system but they are no longer written to.

Jay,
I was under the impression that the standby would need them once it
became the primary. Since they switch roles, doesn't the new primary
(old standby) use online logs and sync them to the standby logs on the
new standby (old primary) once it's back online?
