messaging

问题 I'm in complete lack of understanding in this. Maybe this is too broad for stack, but here it goes: Suppose I have two programs (written in C/C++) running simultaneously, say A and B, with different PIDs. What are the options to make then interact with each other. For instance, how do I pass information from one to another like having one being able to wait for a signal from the other, and respond accordingly. I know MPI, but MPI normally works for programs that are compiled using the same

问题 Edited Question : I am working on a multithreaded JMS receiver and publisher code (stand alone multithreaded java application). MOM is MQSonic. XML message is received from a Queue, stored procedures(takes 70 sec to execute) are called and response is send to Topic within 90 sec. I need to handle a condition when broker is down or application is on scheduled shutdown. i.e. a condition in which messages are received from Queue and are being processed in java, in the mean time both Queue and

问题 When we design the application how to select Topic/Queue type implementation. I am aware of, a) If more than one consumer use the message then use Topic b) If only one consumer then use Queue Please provide any more points need to be considered? For example, concurrency, message persistence, load balancing, anything else? Thanks. Rw 回答1: That's not entirely true about if only one Consumer use a Queue. We have a Java EE app where we rate insurance quotes. We have a RatingIn queue and a

问题 Can any one help me with sending MMS programmatically in android, since I am new to developing, I am having trouble understanding this link!.

问题 I have an app with two threads, 1 that writes to a queue and the second one that read async from it. I need to create a third one that generate 20 more. the newly created threads will run till explicitly stopped. those 20 threads should get "live" data in order to analyze it. each of the 20 has a unique ID/name. I need to send the relevant data (that the READ thread collect) to the correct thread (of the 20 threads). e.g. if the data include a string with id (in it) of 2 --> I need to send it

问题 I've been playing with Faye and have gotten a test rails application to work on my computer's browser (Chrome 30.0.1599.101), but when I tried to access the same page on my iPad the messaging seemed to be broken. As far as I can tell, it seems that websockets, the technology used by Faye, isn't supported on most mobile browsers. I tried Chrome, Firefox, and Safari on the iPad and couldn't get Faye to work on any of those. Is there a mobile browser that supports Faye or some other messaging

问题 I'm interested to use Kafka in one of my projects, but there is a requirement that the messaging broker have to keep the the messages when one of the subscriber (consumer) is disconnected. I see that JMS have this feature. In the website it said that Kafka had durability features. Is it the same like JMS or is it have different meaning ? 回答1: Consumer pulls the data from kafka (brokers). Consumer specifies the offset from where it wants to gather the data. If Consumer disconnects and comes
