The MaximumPendingMessageLimit option is doesn't work in .Net
--------------------------------------------------------------
Key: AMQ-2164
URL: https://issues.apache.org/activemq/browse/AMQ-2164
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.2.0
Environment: ActiveMQ 5.2, XP 64,NMS, NMS.ActiveMQ, vs2008 ,java1.6
ant build the activemq
Reporter: xinfang.yuan
Priority: Critical
I tried to test the MaximumPendingMessageLimit property in donet . But it
doesn't work. i tried to setup it in Code, and ActiveMQ.XML ,it both doesn't
work
1. Create a durable consumer
2. Create a producer and send message in topic (persistent send)
3. Consumer get message and try to block the consumer speed. (speed is slow )
4 Go to web console check the pendingmessage number
The number should be keeping the maxpendingmessage number. My consumer is slow
the producer is faster. But I found out the number is still grow.
i will create another test poster and attach the test file in there

By the way there have another people test it , it also doesn't work for Java.

Thanks
Sample code---- include connection, session, consumer and producer
---------
public TopicConnection(IConnectionFactory connectionFactory, string clientId,
string topicName)
{
this.connection = connectionFactory.CreateConnection() as Connection ;
this.connection.ClientId = clientId;
if (!this.connection.IsStarted)
{ this.connection.Start(); }
this.session =
this.connection.CreateSession(AcknowledgementMode.ClientAcknowledge) as Session;
session.MaximumPendingMessageLimit = 10;
session.PrefetchSize = 20;
this.topic = new ActiveMQTopic(topicName);
}
-------------------------------
----- running another console to get message--
IMessageConsumer consumer = this.session.CreateDurableConsumer(this.topic,
consumerId, "2 > 1", false);
consumer.Listener += new MessageListener(consumer_Listener);
void consumer_Listener(IMessage message)
{
ActiveMQTextMessage msg = message as ActiveMQTextMessage;
Console.WriteLine("Message received:" + "Id = " + msg.NMSMessageId + ",
Content:" + msg.Text); Thread.sleep(1000);//block here message.Acknowledge();
}
---- running another console to send message
IMessageProducer producer = this.session.CreateProducer(this.topic);
while (true)
{
publisher.SendMessage("Message:" + DateTime.Now.ToString("yyyy-mm-dd
HH:MM:ss") + "---" + i.ToString() );
}
And both setup it into activemq.xml
