We will list some of the useful mq commands which we use regularly during day to day operations .

crtmqm QMGRNAME

2.display QMGR status

dspmq

3.display MQ version ,Instance Name ,Binary path ,Data Path etc

dspmqver

4.Create Queue

DEFINE QLOCAL(QNAME)

5.Create Listener

DEFINE LISTENER(LISTERNAME) PORT(PORTNO) TRPTYPE(TCP)

6.Stopping qmgr

endmqm QMGRNAME

7.Delete QMGR
