OK, till now, everyone tell me the correct one is the well known one (aka the 1st one I list).

But, how about the 3rd one I mentioned, even only set FAL_SERVER in standby site is enough, if consider about role switch, I would add FAL_SERVER=STANDBY in primary site.

How about the FAL_CLIENT? any usage?
