# Variable Name: init_slave #
|
|
# Scope: GLOBAL #
|
|
# Access Type: Dynamic #
|
|
# Data Type: string #
|
|
# Default Value: #
|
|
# Range: #
|
|
# #
|
|
# #
|
|
# 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 #
