two data, a process to simplify the order, add one orders, minus one inventory. While orders and inventory are independent services, how to ensure data consistency. At this time we need to think about how to ensure that two remote calls "simultaneous success", the data consistent. Please note that the most depressing thing about remote invocation is that there are 3 kinds of results, successes, failures, and timeouts. A successful failure is possible if it is timed out. General solution, most o

IBM WebSphere MQ programming consists of two parts: MQ system management programming and MQ application development programming. /* Reprinted Please retain copyright: Author: Lei Lin QQ: 64607646E-mail: ralinlei@gmail.com*/ 1MQProgramming Overview IBM WebSphere MQ programming consists of two parts:

MQ sets all queues ManagementImportant changes to the data controlled by the device to the log. This includes creating and deleting objects (except channels), persistent message updates, transaction statuses, modifying object attributes, and channel activities. The log contains the information required to restore updates to all message queues through the following operations: 1. record changes made by the queue manager 2. Record of the queue update us

Stack. 2.5 Message Communications Message communication means that Message Queuing generally has an efficient communication mechanism built into it, so it can also be used in pure message communication. such as the implementation of point-to-point Message Queuing, chat room and so on. Point to Point CommunicationDesign of point-to-point communication architecture In the point-to-point communication architecture design, client A and client B share a message queue, which can realize the message c

Introduction to MQ: MQ is all called the message queue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by writing and retrieving data (messages) for applications that enter and leave the queue, without requiring a private connection to link them. Message passing refers to the process of communicating betwe

1. MQM: Message Queue Manager. A container that loads and manages MQ objects such as messages, queues, channels, processes, topics, listeners, services, name lists, authentication information, and the Queue Manager is responsible for maintaining the queues it owns and storing all messages it receives to the appropriate queues. The Queue Manager is a basic, independent execution unit in WebSphere MQ. A singl

WebSphere MQ Special case of message sending and receiving errorsAuthor: Zheng Zuo Date: 2007-11-6 SummarySome time ago, when the organization implemented the BizTalk Server 2006 application integration project, when using the MQSeries adapter, it encountered packet data loss during transmission in the message queue, the WebSphere MQ Queue Manager channel will be disconnected and retry failed. This problem

First, the basic concept (original address: Click to open the link)For MQ, we need to know 4 nouns: Queue Manager, queue, message, channel; For programming designers, it is usually more about messages and queues, and for maintenance managers, the queue managers and channels are often more concerned.If we compare the queue Manager to a database, then the queue is one of the tables, and the message is a record in the table. Queue: We can simply

Ways to handle large messages in WebSphere MQ As readers who have used WebSphere MQ know, WebSphere MQ is limited in size to the single message being processed, the maximum message currently supported is 100M, and the performance of WebSphere MQ processing decreases as the message size increases. From best practices,

In order to facilitate the subsequent implementation on AIX 5L, I use the Windows XP command method to describe the process. The experiment was conducted as a Wednesday demonstration of the company's presentation. My MQ installation uses GUI mode, installed under C:/Program Files/ibm/websphere MQ, so do not repeat The configuration is deployed as follows:Microsoft Windows XP [version 5.1.2600](C) Copyright

Differences between MQ and Webservice and MQWebservice Webservice and MQ (MessageQueue) are both common methods for cross-platform communication. What are the differences between them?I personally think the most essential difference is that Webservice is almost real-time communication, while MQ is usually delayed communication. What does it mean? Because webservi

The application uses MQ, but MQ does not have a suitable monitoring page. The monitoring methods are relatively scarce and there was a fault last Saturday. If there was a monitoring method for MQ at that time, it can detect problems in time and prevent faults. Before that, I want to write a program to monitor the queue depth in

1) point-to-point communication: the point-to-point mode is the most traditional and common communication mode. It supports one-to-one, one-to-many, multiple-to-many, multiple-to-one, and other configuration methods, supports tree, mesh, and other topology structures. 2) Multi-Point broadcast: MQ is applicable to different types of applications. The important and developing application is the "Multi-Point broadcast" application, which can send messag

MQ is an application. Program The communication method of the application. Applications write and retrieve data (messages) for applications in the inbound and outbound queues to communicate with each other without dedicated connections. Message transmission refers to the communication between programs by sending data in messages, rather than by directly calling each other. Direct calls are usually used for such remote process calls. Queuing means tha
