// MAYBE YOU ASK WHY WE DO TWO CONNS TO SAME db?
// NORMALLY, THEY ARE TWO DIFFERENT db's, MAIN and
// BACKUP.  IN A failover SITUATION, BACKUP DB IS 
// DOING BOTH JOBS, SO BOTH CONNS TO SAME MACHINE

// OUR PROBLEM FIXED WITH CONDITIONAL CODE: EG: IF
// MAIN AND BACKUP DBS ARE SAME, DON'T MAKE SECOND 
// CONNECTION, BUT .... THOUGHT YOU SHOULD KNOW
// ABOUT THIS.
