# This is an auxiliar script that sets the binlog-row-image
|
|
# on a set of connections. These connections are passed as
|
|
# a parameter to this script. Its format is the following:
|
|
#
|
|
# <conid,value,Y_or_N>:[<conid,value,Y_or_N>:...]
|
|
#
|
|
# In detail:
|
|
#
|
|
# conid -- connection id (eg, master)
|
|
# value -- binlog_row_image value to set (eg, FULL)
|
|
# Y_or_N -- Issue stop and start slave (eg, Y)
|
|
#
|
|
# Sample usage:
|
|
#
|
|
# -- let $row_img_set=master:FULL:N,slave:MINIMAL:Y
|
|
# -- source include/rpl_row_img_set.inc
|
|
#
|
|
# Notes:
|
|
#
|
|
# 1. This script saves and restores the original connection that was
|
|
# in use at the time it was included.
|

-- let $old_conn= $CURRENT_CONNECTION
