Я бы изменил ваше приложение таким образом.
void testCommitBackout()
{
string hostName = "localhost";
int port = 1414;
string channelName = "SVRCONN_CHN";
string queueName = "QU1";
int numberOfMsgs = 10;
string queueManagerName = "QM1";
int queueOpenOptionsForPut = MQC.MQOO_OUTPUT + MQC.MQOO_FAIL_IF_QUIESCING;
int queueOpenOptionsForGet = MQC.MQOO_INPUT_AS_Q_DEF + MQC.MQOO_FAIL_IF_QUIESCING;
string messageString = "Bunyamin Test";
MQQueue queue;
Hashtable properties = new Hashtable();
properties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);
properties.Add(MQC.HOST_NAME_PROPERTY, hostName);
properties.Add(MQC.PORT_PROPERTY, port);
properties.Add(MQC.CHANNEL_PROPERTY, channelName);
properties.Add(MQC.USER_ID_PROPERTY, "myuserid");
properties.Add(MQC.PASSWORD_PROPERTY, "Mylongpassword");
// PUT MESSAGES
var queueManager = new MQQueueManager(queueManagerName, properties);
queue = queueManager.AccessQueue(queueName, queueOpenOptionsForPut);
// putting messages continuously under a syncpoint and commit after that
for (var i = 1; i <= numberOfMsgs; i++)
{
var mqpmo = new MQPutMessageOptions();
mqpmo.Options |= MQC.MQPMO_SYNCPOINT;
var message = new MQMessage();
message.WriteString(messageString);
System.Console.Write("Message " + i + " <" + messageString + ">.. ");
queue.Put(message, mqpmo);
System.Console.WriteLine("put");
}
// Now commit all 10 messages.
queueManager.Commit();
queue.Close();
queueManager.Disconnect();
//GET MESSAGES
queueManager = new MQQueueManager(queueManagerName, properties);
queue = queueManager.AccessQueue(queueName, queueOpenOptionsForGet);
// Get messages under syncpoint
for (var i = 1; i <= numberOfMsgs; i++)
{
// creating a message object
var message = new MQMessage();
var gmo = new MQGetMessageOptions();
gmo.Options |= MQC.MQGMO_SYNCPOINT;
queue.Get(message, gmo);
System.Console.WriteLine(i + " .Message " + i + " got = " +
message.ReadString(message.MessageLength));
message.ClearMessage();
}
// Backout all messages.
queueManager.Backout(); //I EXPECT 10 MESSAGES SHOULD GO BACK TO QUEUE?
queue.Close();
queueManager.Disconnect();
}
Надеюсь, это помогло.
