Enables or disables the plugin that handles the ndb_transid_mysql_connection_map  table in the INFORMATION_SCHEMA  database. Takes one of the values ON , OFF , or FORCE . ON  (the default) enables the plugin. OFF  disables the plugin, which makes ndb_transid_mysql_connection_map inaccessible. FORCE  keeps the MySQL Server from starting if the plugin fails to load and start.
