Hi,
I want to move two different qmanger running on two different machines and on two different ports on to a single machine .
I know running two different qmanager on same port and single machine is not possible , Can this be done using qmanager alias ?

Why would you want two processes, queue managers or anything else for that matter, listening on the same port?

If what you're saying is that you currently have 2 queue managers & you want to replace them with a single queue manager that handles traffic for both queue managers then yes, you could use an alias to readdress traffic to the "missing" queue manager.

You can configure two queue managers on the same machine, and they can both have a listener running on port 1414.
Just not on the same IP address.
You *can* configure the listener to bind ONLY to a *specific* IP address. It doesn't do this by *default*.
You could even have the same hostname resolve to *both* IP addresses.
Your applications might not like not knowing which qmgr they have connected to, however.
OR they might be just fine with that. But your other qmgrs won't be.... |

@ mqjeff . I assigned one additional IP to my linux box and then tried to bind the listener on this additional IP for the qmanager on the same port (1416) . And get below error
runmqlsr -t tcp -p 1416 -i 10.10.212.165 -m TESTQM
03/29/2011 07:19:40 AM AMQ9218: The TCP/IP listener program could not bind to port number 1416.
this port is already being used by another qmgr on the very same machine |

| And how did you configure the listener for the OTHER qm? |

runmqlsr -t tcp -p 1416 -m FXQM1
And i checked the netstat on the machine and can see that 1416 is bind to other IP .
tcp 0 0 10.10.212.15:1416 |

So you didn't read the manual properly, particularly the last sentence of the -i IPAddr block of the runmqlsr command (note that I make a statement, not ask a question). And why are you using that command anyway? Why are you not using a listener object?
