mqseries_back — MQSeries MQBACK
The mqseries_back() (MQBACK) call indicates to the queue manager that all the message gets and puts that have occurred since the last syncpoint are to be backed out. Messages put as part of a unit of work are deleted; messages retrieved as part of a unit of work are reinstated on the queue.
Using mqseries_back() only works in conjunction with mqseries_begin() and only function when connecting directly to a Queueu manager. Not via the mqclient interface.
hConn
Connection handle.
This handle represents the connection to the queue manager.
compCode
Completion code.
reason
Reason code qualifying the compCode.
No value is returned.
Example #1 mqseries_back() example
<?php
mqseries_back($conn, $comp_code, $reason);
if ($comp_code !== MQSERIES_MQCC_OK) {
printf("CompCode:%d Reason:%d Text:%s<br>\n", $comp_code, $reason, mqseries_strerror($reason));
}
?>Note:
mqseries_back() will not function when using MQSeries Client to connect to a Queueu Manager.
