Hi Guys,
I would like to know the range of ports used by a QM and a Broker.
I know 1414 is the default listener TCP/IP port of a QM. But I have changed that in my previous projects to 1415 also. I would like to know is there any defined range of ports as we have for Integration Server HTTP/HTTP(S) ports spanning from 7800-7842 and 7843-7884.
Also, apart from the ports mentioned above used by Integration Server, I used to see the ports 7800 and 7843 that a Broker HTTP/S listens to.
Why I have this requirement is I need to have access to IIB Pre-prod and Prod environments. Hence I need to raise a request for opening the ports. |

Each MQ listener uses a fixed port.
There's only one well known port for MQ and that's 1414. I think 1415 is actually a well known port for something else.
But there's no reason to use any specific port # for MQ at all. You don't even need to use a single listener.
There are pros and cons to using more than one listener. It's very situation-ally dependant.
You can't just randomly raise a request to open port XYZ and expect it to point to a queue manager or an HTTP port on IIB. Or etc. etc. etc.
You have to know the configuration of the queue manager and of the HTTP endpoints for IIB.
I'd be surprised if you were given access to the production environment.

The range is defined by whomever installs the QM and broker - assuming that they always customise it.
It's best to choose non-default ports to avoid conflicts if running more than one QM or broker on the same host.
In broker, one can also assign a port range for auto allocation by EGs, but I prefer to fix ports per execution group so that their value is predictable.
The broker listener and EG listeners will have different ports, you can display those in use with various report commands, although you would have to list every EG to be sure of capturing any EG level listener.

Especially when you have to open a firewall. Better to open a specific port than open a range, and leave unused ports for an intruder to use.
