The DBMS_AQ package has a method called POST. The documentation says, This procedure posts to a list of anonymous subscriptions, allowing all clients who are registered for the subscriptions to get notifications of persistent messages. This feature is not supported with buffered messages. and This call provides a be...
I'm developing a set of applications that work together to create a system for processing metering data. There's several reasons I want to have them loosely coupled and the system should be extensible by third parties, so the apps will be tied together via messaging. I'm looking for a messaging system that offers bindings in (at least) ...
Are/were you using XmlBlaster? What do you think about it? What are its weaknesses and strengths? ...
Is there any security issue if let say in one application we do a hidden post to another application to make use of that application functionality? ...
I'm about to start a project that requires XML messages to be sent between a couple of servers over HTTPS. A brief summary is this: I have an application in use by clients that will send information to a central server. That server will communicate these XML messages to another company's server. I will also receive messages back from ...
I'm using the CDO.Message class to create and send an email from a Visual FoxPro application. I've tested that it works while the user is connected to the internet, and it even seems to work when I send while disconnected from the network, it simply gets sent when the client gets reconnected. One issue I have with the .Send() method of...
Hi Im trying to start iexplore.exe let it run for 5 seconds and then close it again. iexplore opens just fine however it doest close when i call the PostThreadMessage can any one see what im doing wrong here is the code: CString IEPath = "C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE";//GetIEPath(); //IEPath += ' ' + url; std::st...
Hi, One of my programs requires a reliable way to log across unreliable network (ie internet). The sender or receiver may go offline any time and can come back later. But any message sent by client should not be missed. Obviously syslog does not fit the bill. I am exploring the use of messaging servers like Apache ActiveMQ instead of sy...
I come from a background of MoM. I think I understand ESB conceptually. However, I'm not too sure about the practical differences between the two when it comes to making a choice architecturally. Here is what I want to know 1) Any good links online which can help me in this regard. 2) Can someone tell me where it makes sense to use on...
Is there a free API or some other way to determine what carrier a cell phone number is registered with? I'd like my application to broadcast text messages without them picking their carrier from a list. UPDATE: Interestingly, a coworker found the answer: http://developer.whitepages.com/ UPDATE2: Well the whitepages license agreement ...
Ever since the publication of Enterprise Integration Patterns people have been using the notation introduced in that book for documenting asynchronous heterogenous messaging systems. But our shop is more or less standardized around a proprietary documentation tool that does exclusively UML. Is one of the standard UML diagrams appropriat...
I'm considering using AMQP (using qpid) to enable a mixture of Python and Java services communicate with each other. Basic text messaging seems simple enough but, as with every other messaging technology I've investigated, that's where it seems to stop. Except for building instant messaging applications, I would have thought sending stri...
If you had to write code that takes messages from a message queue and updates a table in a database, how would you go about structuring it in a good oo way. How would you structure it? The messages is XML data, one node per row in the table. The rows in the table could be updated, deleted or inserted. ...
I need to use one logical PGM based multicast address in application while enable such application "seamlessly" running across several different geo-locations (i.e. think US/Europe/Australia). Application is quite throughput (several million biz. messages a day) and latency demanding whith a lot of small but very frequently send message...
Background I'm researching the efficiency of messaging within contemporary web applications, examining the use of alternatives to XML. This is a university project whose results will be released publicly - the greater the participation of the community, the greater the value of the results that are given back. I need as many real-life e...
I'm using ActiveMQ 5.2 and my application requires a large number of topics, somewhere in the neighbourhood of 500,000. When I run my application, after creating only about 1000 topics, ActiveMQ throws an OutOfMemoryException. Is it unreasonable to expect ActiveMQ to support this number of topics? Is there an optimal configuration for...
Hi, To cut a long story short, I am working on a project where we are rewriting a large web application for all the usual reasons. The main aim of the rewrite is to separate this large single application running on single server into many smaller decoupled applications, which can be run on many servers. Ok here's what I would like: I ...
Hi, I'm not sure if there many Mule users on here but I'm hoping someone might be able to help me! I'm having a problem calling a webservice from Mule using Axis. I've created a fairly simple example where I have xml in a file being read by Mule, it's then transformed into a Document and sent to the webservice. The relevant code in the...
Is anyone using Google's protocol buffers in large scale applications in production. What is the experience that people have had? ...
I wrote a multi-threaded windows application where thread: A – is a windows form that handles user interaction and process the data from B. B – occasionally generates data and passes it two A. A thread safe queue is used to pass the data from thread B to A. The enqueue and dequeue functions are guarded using a windows critica...
