rpl_row_img_set.inc

#
# 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
