Yes, but you can open the physical standby read only... let them do some
reporting -- hence need temp tablespace. Then restart managed recovery.
Now tempfiles are there permanently... And in an emergency that step is
already done making failover more automatic.

Consider :
1. Monday : You do a first clone to the Standby without the
TEMPFILE
2. Tuesday through Thursday: Your Standby in MOUNT state is
always "rolling forward"
through ArchiveLogs shipped from the Primary
3. Friday morning : Your Primary goes DOWN. No access to the
Primary Storage at all.
4. Friday afternoon: You OPEN the Standby.
Hmm. .. we don't have the TEMPFILE .
Let's add the TEMPFILE.
5. Friday evening : Users are happy, transactions continue..
When would you have been able to copy the TEMPFILE ?
A Standby HAS to assume that the TEMPFILE is not available.
