Hello,
I've got a simple windows XMS application sending messages with persistence set to queue default.
msg.SetIntProperty(XMSC.JMS_IBM_MQMD_PERSISTENCE, MQC.MQPER_PERSISTENCE_AS_Q_DEF);
| Code: |
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using IBM.XMS;
namespace XMSSendTest
{
class Program
{
static void Main(string[] args)
{
IConnectionFactory factory = IBM.XMS.XMSFactoryFactory.GetInstance(XMSC.CT_WMQ).CreateConnectionFactory();
factory.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, "qmgr");
factory.SetStringProperty(XMSC.WMQ_CHANNEL, "chl");
factory.SetStringProperty(XMSC.WMQ_HOST_NAME, "host");
factory.SetIntProperty(XMSC.WMQ_PORT, 1414);
IConnection connection = factory.CreateConnection();
ISession session = connection.CreateSession(false, AcknowledgeMode.AutoAcknowledge);
IMessage msg = session.CreateBytesMessage();
System.Console.WriteLine("DELIVERY: " + msg.JMSDeliveryMode);
msg.JMSDeliveryMode = DeliveryMode.DELIVERY_MODE_NONE;
msg.SetIntProperty(XMSC.JMS_IBM_MQMD_PERSISTENCE, MQC.MQPER_PERSISTENCE_AS_Q_DEF);
IDestination queue = session.CreateQueue("QUEUE.OUT");
IMessageProducer producer = session.CreateProducer(queue);
producer.Send(msg);//, DeliveryMode.DELIVERY_MODE_NONE, 1, 100);
System.Console.WriteLine("Msg sent.");
}
}
}

echo "dis qa(QUEUE.OUT) DEFPSIST" | runmqsc QMGR
5724-H72 (C) Copyright IBM Corp. 1994, 2011. ALL RIGHTS RESERVED.
Starting MQSC for queue manager DMQBRK1.
1 : dis qa(QUEUE.OUT) DEFPSIST
AMQ8409: Display Queue details.
QUEUE(QUEUE.OUT) TYPE(QALIAS)
DEFPSIST(NO)
One MQSC command read.
No commands have a syntax error.
All valid MQSC commands were processed.
WMQ version 7.5.0.5
And when I send it to the queue I got:
A VER 2
A RPT 0
A MST 8
A EXP -1
A FDB 0
A ENC 546
A CCS 1208
A FMT MQHRF2
A PRI 4
A PER 1
The default for MessageProducer is Persistent but the queue alias has DEFPSIST set to NO, os the final persistence should be PER 0 (and is PER 1).
Is this a bug in the XMS or do I miss something? |

I would check also the real queue you are pointing with the alias ,to see how the persistence attribute is set...
Hope it helps . |

Thank you for the reply.
This is a pattern we use in the whole enterprise. We set persistence on the alias queue and it works in Java and C++, it just doesn't work under .NET XMS, so I don't think this is queue setup, rather something to do with the implementation of XMS (or maybe I'm missing something in my app). |

It's important to note that a queue doesn't have persistence. It has default persistence.
If it doesn't work in .NET, then perhaps .NET isn't setting Persistence as Queue Definition.
I know your code is trying to set that. Which version of the .NET MQ classes are you using? With which version of .NET ?
Can you run an mq client trace to see what MQ thinks you're doing under the covers?
