If you have a standby that has never been opened, you won't have REDO or
TEMP. Those do get created as the database is being opened. From what I
remember, the TEMP thing isn't just for standbys. If you shut down a
"primary" database and delete the temp files, it will recreate them on the
way back up, as well.
