# #
# Creation Date: 2008-03-08 #
# Author: Rizwan #
# Modified: HHunger 2008-09-29 Fixed the bug by inserting the usual wait and #
# SQL-Satements to control master and slave, #
# deleted the sleep and made improvements like: #
# - Replaced the opt file by dynamic variables, #
# - Made the tests independant of the initial #
# values of the global variables, #
# - Reduced the test to the needed test case to #
# save run time, #
# - Beautification. #
# #
# Description: Test Cases of Dynamic System Variable init_slave #
# that checks the behavior of this variable #
