Hello,

I just saw a few qmgrs where listeners are in running state, but when I issue the display command it says object not found.

Is this possible? I can see the runmqlsr process with ps -ef command as well.

How did you see listeners running? What commands did you issue?

Sure its possible - if the listener was started at a shell, and not from a listener object. Its the same executable runmqlsr.

Dis lsstatus(*)

This is an MQSC command that displays status of listener object named in the ( )'s.

This is a UNIX command to list processes, in this case, a process called runmqsr. If you have multiple qmgrs in the same o/s instance, you will likely have multiple runmqlsr's.

The executable is the same.

IMHO, the value of the listener OBJECT is that you can specify CONTROL(QMGR) which starts the listener when the qmgr starts up, and ends it when the qmgr shuts down.

It depends on the options you used to start the listener on the command line.

Specifying option "-r":
Code:
$ runmqlsr -r -m MYQMGR -t TCP -p 11402 &

$ runmqsc MYQMGR
5724-H72 (C) Copyright IBM Corp. 1994, 2019.
Starting MQSC for queue manager MYQMGR.


AMQ8706I: Request to stop IBM MQ Listener accepted.
dis lsstatus(*)
     3 : dis lsstatus(*)
AMQ8147E: IBM MQ object * not found.


Omitting the option "-r":
Code:
$ runmqlsr -m MYQMGR -t TCP -p 11402 &

$ runmqsc MYQMGR
5724-H72 (C) Copyright IBM Corp. 1994, 2019.
Starting MQSC for queue manager MYQMGR.


dis lsstatus(*)
     1 : dis lsstatus(*)
AMQ8631I: Display listener status details.
   LISTENER(SYSTEM.LISTENER.TCP.1)         STATUS(RUNNING)
   PID(28049422)
