IBM's MQ Usage guide

With the development of computer network and distributed application, remote message transmission is becoming an indispensable part of application system.

The emergence of commercial message middleware ensures the reliability, high efficiency and security of message transmission, and also reduces the development cycle of the system.

Currently, the most widely used message middleware products are IBM MQSeries.

The Dongfeng piping System is communicated through MQ.

In this paper, the basic operation and configuration of MQ is elaborated in detail, hoping to help readers. 

A MQ Basic Operations 

There are several important components in MQ: Queue Managers (QueueManager), queues, and channels (channel). Its basic operating methods are as follows: 

Create a Queue Manager 

Crtmqm–q Qmgrname 

-Q refers to creating a default queue Manager 

To delete a queue Manager 

DLTMQM Qmgrname 

Start the Queue Manager 

STRMQM Qmgrname 

If you are starting the default Queue manager, you can do so without its name 

Stop Queue Manager 

ENDMQM Qmgrname controlled stop 

Endmqm–i Qmgrname immediately stop 

Endmqm–p qmgrname Force Stop 

Show Queue Manager 

Dspmq–m Qmgrname 

Run the MQSeries command 

RUNMQSC qmgrname 

If it is the default queue manager, you can not take its name 

Put a message in the queue 

amqsput QName qmgrname If the queue 

is a queue in the default Queue manager, you can not take the name of its queue manager 

Remove a message from 

a queue amqsget QName qmgrname If the queue 

is a queue in the default Queue manager, you can not take the name of its queue manager 

Start channel 

runmqchl–c chlname–m qmgrname 

Start listening 

runmqlsr–t type–p port–m qmgrname 

Stop listening 

endmqlsr-m qmgrname

where the value of Appltype can be: CICS, UNIX, WINDOWS, WindowsNT, etc. 

Create sender Channel 

DEFINE Channel (sdrname) Chltype (SDR) + 

CONNAME (' 100.100.100.215 (1418) ') XMITQ (qtname) REPLACE 

The Chltype can be: SDR, SVR, RCVR, Rqstr, Clntconn, SVRCONN, CLUSSDR, and CLUSRCVR. 

Create receiver Channel 

DEFINE channel (sdr_ TEST) chltype (RCVR) REPLACE 

Create a server connection channel 

DEFINE channel (svrconnname) Chltype (SVRCONN) REPLACE
