[Asterisk-Users] asterisk load balance

[unplug]

I am confusing where the asterisk should store the register
information in realtime mode.
As in my configuration,
UA1 ---- asterisk1 +
UA2 ---- asterisk2 + database
UA3 ----- asterisk3 +
3 UAs connected to 3 asterisk with a common database to store user
information and dial plan.  However, asterisk1 seems doesn't know
there are UA2 and UA3 already registered in the system.
I wonder the register information should be store in DB.  When there
is a invite request, asterisk will query the database and find out the
calling party contact information.  Am I right?  But in the case
above, asterisk only know the UA which register to it.  Anyone can
tell me the real mechanism of realtime for the UA registration?  How
and where asterisk to get the user registration when there is an
invite comming?
