Hi

*think* but I may have entirely misread the comment that point 4 is just wrong.
It sounds like you only have one raid 5 set (which is shared between 2
machines). If this is the case then the clustering has no effect on the fault
tolerance/performance of the raid 5 set.
Verification was easy. We just powered down the primary machine, changed the
db name in the external table, drop the replication on the backup server and
restart the application. Everything worked fine. After 2-3 days, over the
weekend, we rebuilt the replication again.

_wait_for_sync basically meant that a session is waiting for the sync of the
redo by the lgwr. Normally the redo log writer writes to disk and then
notifies the session that the transaction is completed. By setting this to
false, you no longer wait for the redo to go to disk.
That has no impact
This one is easy:
look in v$waitstat. That has the class numbers for all block classes. Then
add to that the undo segments. Each undo segment has two types of class. A

some disk writes need to wait for the LGWR to flush the corresponding redo
to disk. So now you can have a situation that the blocks that are dirty are
