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.
