BUG#12535301- SYS_VARS.RPL_INIT_SLAVE_FUNC MISMATCHES IN DAILY-5.5 Problem: sys_vars.rpl_init_slave_func test was not recorded after the last edit. It was disabled on 5.1 after seeing failures due to the above reason. No old failures as this suite never ran with pb2 on 5.1 Fix: Added assert condition after wait for checks. Recorded test and enabled it.

# 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. #
