You want to know if the MQ Listener process "runmqlsr" is running for an IBM MQ queue

manager in Windows and Linux in a local host. That is, you are logged in in host-1 and you

want to know if there is an MQ listener running in host-1.

However, for a related scenario, if you are in host-2 and you want to know if there is an MQ

listener in another host (host-1), then the following technote can be helpful:

Using ssh to test connectivity between an IBM MQ Client in one host and

a Queue Manager in another host

In this example, the MQ listener object "LISTENER" is running in port "1414".

Use "runmqsc" to display the Listeners and their Status.

$ runmqsc QMGR1

display listener(*) all

AMQ8630I: Display listener information details.

LISTENER(SYSTEM.DEFAULT.LISTENER.TCP) CONTROL(MANUAL)

TRPTYPE(TCP) PORT(0)

AMQ8630I: Display listener information details.

PID(43735) PORT(1414)

++ Linux

In this example, there are 2 queue managers, each one with its own Listener port.

When the MQ queue manager is running, the listener runs under the process name:

runmqlsr

+ Using ps -ef

You can also use the utility "netstat" as follows, to see if the port used by the Listener (such

as 1414) is active and in "LISTEN" mode.

+ Using netstat

The Unix command "netstat" can be used with the following options:

-a show all

-n show the number that is mentioned in the file /etc/services

That is, do not try to replace it with the name of the service

tcp6 0 0 :::1414 :::* LISTEN 43735/runmqlsr

++ Windows

+ Using line command

Note: Thanks to Bob Gibson for his valuable feedback in providing this variation!

C:\> tasklist | find "runmqlsr"

runmqlsr.exe 24176 Services 0 9,772 K

+ Using Task Manager

You can use the Task Manager as follows.

You will need to add the extra column for "Command line" in order to see the details.

Launch Task Manager:

Right click the Process and click "Goto Process Details"

Right click on any column and select "Show Columns" and then check "Command Line"

option > Click OK.

Select the desired process, such as runmqlsr.exe and see the text in the column "Command

line":

+ Using netstat

The options for netstat are:

-a Displays all connections and listening ports.

-b Displays the executable involved in creating each connection or listening port.

-n Displays addresses and port numbers in numerical form.

-o Displays the owning process ID associated with each connection.

a) The following command shows one line per port, which is easy to parse:

b) The following command uses the -b option, but unfortunately the output uses several

lines for each port, which makes it harder to parse.

You may not have C:\temp, thus, capture the output into a temporary directory:

C:\> netstat -anob > c:\temp\netstat-out.txt

C:\> notepad c:\temp\netstat-out.txt

[runmqlsr.exe]
