# Author: Serge Kozlov <Serge.Kozlov@Sun.COM>
# Date: 02/19/2009
# Purpose: Testing basic functionality of heartbeat.
# Description:
# * Testing different values for slave_heartbeat_period.
# * How to affect various statements to slave_heartbeat_period
# * Various states of slave and heartbeat
# * Various states of master and heartbeat
# * Circular replication
