# ************************************************************
# wl6504: This testcase is to check the functionality of the
# innodb_buffer_pool_dump_pct flag
# step 1.Set innodb_buffer_pool_dump_pct=100 and take the dump
# step 2.Set innodb_buffer_pool_dump_pct=1 and take the dump
# step 3.Compare the size of both the dump files

#***********************************************************
# SELECT *
# FROM information_schema.global_status
# WHERE variable_name = 'INNODB_BUFFER_POOL_DUMP_STATUS'
# gives
# a) VARIABLE_NAME VARIABLE_VALUE
# INNODB_BUFFER_POOL_DUMP_STATUS not started
# in case there was no innodb_buffer_pool_dump since server start.
# b) Something like
# VARIABLE_NAME VARIABLE_VALUE
# INNODB_BUFFER_POOL_DUMP_STATUS Buffer pool(s) dump completed at 130711 13:43:24
# in case there was a innodb_buffer_pool_dump since server start.
# Attention:
# - There is no guarantee that the current test is the first test which
# made an innodb_buffer_pool_dump since server startup.
# - The granularity of the timestamp is one second.
# - There could have been some dump caused by some previous test
# just a few milliseconds before.
