Hi all, is there any information on the future of the Service Broker infrastructure in SQLServer? The team's blog (http://blogs.msdn.com/b/sql_service_broker/) is not very active and there were only minor changes in SQL 2008 R2 release. When building now a distributed system that needs async queueing and there is already a SQLServer / ....
Is it possible to check for messages from Qpid queue from unix/windows console? Here is how I check via GUI : http://i47.tinypic.com/pbu5d.gif I can see all the info from Qpid JMX Management Console, is there a something close to this that I can use in console? ...
I have built a variety of little scripts using Ruby's very simple Queue class, and share the Queue between Ruby and JRuby processes using DRb. It would be nice to be able to access these from Scala (and maybe Java) using JRuby. I've put together something Scala and the JSR-223 interface to access jruby-complete.jar. import javax.script...
I have several services on different machines and a message-passing system suits my problem. Reliability - sent messages always delivered, even if one end goes down - is the key concern, although it should also be fast and reasonably bandwidth-efficient. So which message queue should I use? ...
I understand the basics of a message queue system, but I have no idea about the different systems out there. There seem to be a lot of open source and non-open source solutions out there. What are some of the ones out there and which one[s] have the most unique features? [Multicast, p2p, alternative message structures, device detection,...
Is there are an architecture versatile enough that it may be deployed to either a cloud server or to a dedicated (or VPS) server with minimal change? Obviously there would be config changes but I'd rather leave the rest of the app consistent, keeping one maintainable codebase. The app would be ASP.NET &/or ASP.MVC. My dev environment is...
I need to change the C++ code to connect with WebSphere MQ using Client Channel defnition table. There are about 5000+ MQ clients and 10 MQ Servers on Windows 2003 with v6.0. Please help me if any one using C++ with CCDT. ...
POSIX provides a way to read a message queue using its mq_receive function. This function also removes it from the queue. I need to find a way to check to see if a message is in the queue without removing it. ...
I am having a hard time understanding the ZeroMQ messaging system, so before I dive in, I wanted to see if anyone knew if what I want to do is even possible. I want to setup a pubsub server with ZeroMQ that will publish certain streams of data and to subscribe to some of those streams, a user must authenticate to see if they have acces...
I'm evaluating possible solutions for handling a large quantity of queued messages, which must be delivered to workers at a certain date and time. The result of executing them is mostly updates to stored data, and they may or may not be originally triggered by user action. For example, think of what you'd implement in a hypothetical lar...
Couple of years ago i used some tool to monitor what event messages were being sent to a window. I can't remember the name right now. Can someone please tell me some tool with this functionality. ...
We are currently using a custom queueing system where a table in a SQL Server 2008 database has an xml column with some additional data. We use this when we serialize our objects to XML and store them in this table. Later, another application simply dequeues these items, deserializes them into the same object and preforms a certain task ...
Hello, I am using NServicebus with a pubsub configuration. So far it has been really awesome and quite straightforward. However, I've noticed that one of my subscriber endpoints does not pickup messages that contain HTML/XML strings. For instance I am adding a POCO object that implements IMessage and one of the string fields contains som...
I need to move one single message from an MQ queue to another queue. This other queue may already have existing messages in it. Is there a way to do this? ...
Hi, I'm searching for a minimal message queue project. With minimal I mean something along this: No/Minimal setup / administration Uses http (so I don't need protocol/queue specific libraries/code) (Persistence would get extra points ;) (It should run on linux.) Is there such a project available? I once heard about a message queu...
I am looking for MQ systems (rabbitmq , activemq) for our programs. Almost all MQ run on ports. I was wondering if there are any MQ systems running on smtp or email services. Basically I am trying to avoid the hassle of setting up a new software and opening up ports in different firewalls (its a hassle). ...
If I use durable subscription, can I restart my client and resubscribe without loosing any messages? (Assuming, my client does not unsubscribe in any way. Lets say it just crashes). Let me clarify. JMS 1.1 Spec says the following: 9.3.3.2 Reconnecting to a Topic using a Durable Subscription /* Reconnect to a durable subscription *...
Consider an application with two components, possibly running on separate machines: Producer - Inserts records into a database, but does little to no reading from the database. Multiple instances may be running concurrently. Consumer - Must be notified when a record is inserted into the database by an instance of component A. May also ...
Hi, I'm trying to implement a program where a parent process opens multiple child processes (usually around 40) that run in parallel to each other. Now, I want to be able to get the child processes talking to the parent process to extract some information that only the parent process has. My plan was to use message queues in php but I...
We have an asynchronous backend service, which has a synchronous webservice interface (So basically the client has to call the interface twice). To improve this, we are thinking about moving to a message queue based interface or an asynchronous web service. Since I'm not familiar with asynchronous web service, I'm not sure how to c...
