关注此帖：Get Active QM Instance from Multi Instance Queue Manager and connect
我创建了一个连接
XMSFactoryFactory factory = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ);
IConnectionFactory connectionProperties = factory.CreateConnectionFactory();
connectionProperties.SetIntProperty(XMSC.WMQ_CLIENT_RECONNECT_OPTIONS, XMSC.WMQ_CLIENT_RECONNECT_Q_MGR);
connectionProperties.SetStringProperty(XMSC.WMQ_CONNECTION_NAME_LIST, String.Format("{0}({1}),{2}({3})", element.Host1, element.Port1, element.Host2, element.Port2));
connectionProperties.SetIntProperty(XMSC.WMQ_CLIENT_RECONNECT_TIMEOUT, XMSC.WMQ_CLIENT_RECONNECT_TIMEOUT_DEFAULT);
connectionProperties.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, element.QueueManager);
connectionProperties.SetStringProperty(XMSC.WMQ_CHANNEL, element.Channel);
connectionProperties.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT);
connectionProperties.SetIntProperty(XMSC.WMQ_BROKER_VERSION, XMSC.WMQ_BROKER_V1);
connectionProperties.SetBooleanProperty(XMSC.WMQ_USE_CONNECTION_POOLING, true);
然后是
try
{
using (IConnection connection = _connectionProperties.CreateConnection())
{
connection.Start();
using (ISession session = connection.CreateSession(true, AcknowledgeMode.AutoAcknowledge))
{
using (var scope = new TransactionScope(TransactionScopeOption.RequiresNew))
{
using (IDestination responseQueue = session.CreateQueue(replyToRequestQueue ? _requestQueueName : _responseQueueName))
{
using (IMessageProducer producer = session.CreateProducer(responseQueue))
{
IMessage response = session.CreateTextMessage(message);
if (!string.IsNullOrEmpty(correlationId))
{
response.JMSCorrelationID = correlationId;
}
producer.Send(response);
}
}
scope.Complete();
}
}
}
}
catch (XMSException xmse)
{
if (xmse.LinkedException != null)
{

}
}
发送消息，但它在最后一行生产者处抛出异常。发送（响应）：

XMS attempted to perform an MQPUT or MQPUT1; however WebSphere MQ reported an error.

从跟踪中我可以看到生产者在连接名称列表中有我的两个活动/备用主机，而且“localhost”作为host_name而1414作为端口，这就是为什么我无法连接到它？

不支持使用分布式事务进行自动客户端重新连接，这就是您看到的原因
|XMSException.LinkedException on (SendTextMessage) sending message to Queue handler ABC:(In ABC.XYZ.REQUEST / Out XYZ.ABC.RESPONSE) / xmse.LinkedException.Message : **2012** / xmse.Message : Failed to send a message to destination XYZ.ABC.RESPONSE.
2012年是MQRC_ENVIRONMENT_ERROR。
