# The main logics is resided in the run section which generates
# three types of XA transaction: two kinds of mixed and one on non-transactional
# table.
#
# param $command one of three of: 'setup', 'run'or'cleanup'
# param $xa_terminate how to conclude: 'XA COMMIT'or'XA ROLLBACK'
# param $one_phase'one_phase' can be opted with XA COMMIT above
# param $xa_prepare_opt'1'or empty can be opted to test withand without XA PREPARE
# param $xid arbitrary name for xa trx, defaults to'xa_trx'
# Note ''is merely to underline, not a part of the value.
