# Variable Name: key_buffer_size #
# Scope: GLOBAL #
# Access Type: Dynamic #
# Data Type: numeric #
# Default Value: 131072 #
# Range:8-4294967295 #

# #
# Creation Date: 2008-02-07 #
# Author: Salman #
# #
# Description: Test Cases of Dynamic System Variable key_buffer_size #
# that checks the behavior of this variable in the following ways#
# * Default Value #
# * Valid & Invalid values #
# * Scope & Access method #
# * Data Integrity #
# Modified: Horst Hunger 2008-11-27 #
# Due to OS depending values the check has been changed #
# from concrete values to ranges. #
