Possible Python API Performance Problem

I have been seeing some strange behavior with the 0.20 C++ broker (I see the same behavior in the 0.14 broker as well) when sending / receiving messages with the Python API. It seems that the response time increases for each consecutive message. The client sends a message with a reply-to

RE: Possible Python API Performance Problem

create one per response but never close them. Try adding sender.close() after the send in the service program. -Ted On 04/24/2013 11:50 AM, Wes Parish wrote: I have been seeing some strange behavior with the 0.20 C++ broker (I see the same behavior in the 0.14 broker as well) when sending

JMS Browse Mode

Is it possible to connect to a pre-defined ring queue using JMS in browse mode? If so, are there any examples? Please correct me if I am wrong, but the way I uderstand it browse mode will make a callback for every message on the queue when a user connects, then again for each new incoming

Is it possible to set up a dynamic ring queue using JMS? This is with MRG v1.2. Wes

Large persistent queues

We have a broker with a modest amount of RAM, but a very large disk capacity. Can we create a small in-memory queue, but a large associated journal (for persistence)? Basically, we want to allow a persistent queue to hold a larger number of elements than the broker has physical RAM to store

JMS Question

When a connection exception is thrown because of a socket timeout exception, which occurs when a heartbeat times out, it is not being sent to the onException() method. Should this exception be sent like the others to this method? Wes

Message replay tracker question

I have a question about the qpid::client::MessageReplayTracker C++ class. I am using a MessageReplayTracker to send messages to a broker. Periodically when I close the session and connection object from another thread I receive the following warning message that is printed to stderr: Warning

RE: Running the C++ Broker as a daemon process

I am not sure if Qpid natively supports being installed as a service, but if it doesn't there is another option. You can create a Windows service using SRVANY.exe from the Windows Server 2003 Resource Kit. Basically, you run the SRVANY.exe application and it installs the service to your

Maximum Transfer Rates

Hello, It seems like we are unable to pass the 30-40 MB/s rates (over a 1Gbit link) using the Qpid. We have tried multiple configurations (current qpidd.conf pasted below), but have not had any luck. Has anyone successfully seen ~100MB/s on a 1Gbit link? Thanks, Wes

RE: 0.5 C++ example listener hangs during testing

I have seen similar problems (although no out of order messages so far). I am testing on RHEL5.3 using the C++ API with a MessageReplayTracker to handle failover, and after a failover I am calling replay(). This scenario is a consumer consuming as fast as possible, a producer producing 5k

QPID help

Hello, I would like to thank you guys for a great product, however, I am having a few issues getting qpid setup correctly. I am able to bring up qpid fine on either testbroker1 or testbroker2, but once a broker is running on one machine I am unable to start qpid on the other. The error
