specification for providing a messaging service that develops all the data structures and interaction processes throughout the messaging service delivery process. MQ, the Message Queuing service, is the ultimate implementation of message-oriented middleware (MOM), a true service provider, and the implementation of MQ can be based on JMS or other specifications or standards.

MQ supports multiple programming languages, including C, C ++, Java, VisualBasic, COBOL, PL/1, and RPG. It also supports a variety of popular development tools, such: webSphere Studio Application Developer, powerbuiler, Microsoft Visual C ++, Visual Basic, and Delphi. In addition,

目前业界有很多MQ产品,我们作如下对比:RabbitMQ
是使用Erlang编写的一个开源的消息队列,本身支持很多的协议:AMQP,XMPP, SMTP, STOMP,也正是如此,使的它变的非常重量级,更适合于企业级的开发。同时实现了一个经纪人(Broker)构架,这意味着消息在发送给客户端时先在中心队列排队。对路由(Routing),负载均衡(Load balance)或者数据持久化都有很好的支持。Redis
是一个Key-Value的NoSQL数据库,开发维护很活跃,虽然它是一个Key-Value数据库存储系统,但它本身支持MQ功能,所以完全可以当做一个轻量级的队列服务来使用。对于RabbitMQ和Redis的入队和出队操作,各执行100万次,每10万次记录一次执行时间。测试数据分为128Bytes、512Bytes、1K和10K
Today, social networks are ubiquitous-to connect with friends, to keep up with the times, or to keep people informed of the latest developments in topics of common interest. Social networking is also useful in businesses. This article will show you how to quickly and easily use social networking software (such as Twitter) in your WebSphere MQ application to send status and problem information to a wide range of system administrators or end users, or e
When you create an MQ queue manager, there are a few things to keep in mind:1) The Queue Manager log type and the size and number of log files, according to the size of the user data, the total amount of messages on each queue, to calculate the total capacity of the log, in order to avoid the system in the process of running a log full of the situation;2) A dead-letter queue should be specified and established for the Queue manager;3) The maximum numb
MQSC (MQ Script command), and in RUNMQSC, all commands are converted to full capitalization before committing execution. So if you want to represent size-related strings, such as object names, enclose the string in quotation marks. Enter the following command to start the MQSC command: RUNMQSC [Queuemanagername] --View the MQ version-- Dspmqver --View queue status--Dspmq --Create a queue manager--Crtmqm-
Prepare: Verify that the WebSphere MQ host and the WebSphere Application Server host can ping each other through the host name.
The first step: Install and configure WebSphere MQ on top of the WebSphere MQ host, add an operating system user (such as Mquser), and put him in the group MQM.
Step Two: Create a queue manager, queue, channel using the following command
interaction of the message is bound to be mutual, there is receiving messages, there must be a message. A local queue is used to receive messages that are sent externally, and another local team example is used for transport, which is used for the transmission queue of the remote team example, and sends the message to the local queue of the remote host. In order for a message to be successfully delivered to a remote queue, it is also necessary to configure the channel, typically by specifying t
Queue Management 4.1 Establish a server connection channel on the client
Create a dedicated 'server connection' channel on the managed client, as shown below:
Runmqsc qm_0
Define channel (DC. svrconn) chltype (svrconn) mcauser ('20140901 ')
Alter qmgr ccsid (0, 1381)
Endmqm-P qm_0
Strmqm qm_0
Strmqcsv qm_0
Note:
(1) channel (DC. svrconn) chltype (svrconn) ----- indicates that the established DC. svrconn type is a server connection;

This model unifies the message pattern, such as the previously mentioned publish/subscribe, queue, transaction, and streaming data, and adds additional features such as easier to scale, content-based routing.

The program realizes the function of sending messages and reading messages, see the send*** and get*** methods. This is only appropriate for testing because the program in the environment needs to make a slight change to this, and in the real world it must be in the infinite loop of the while (true) {...} to invoke the Get method, and if there is a value, perform a processing operation on the message, and if there is no value, continue the loop. There is a wait time in the Get method.This proced
