Hi all,
On a few AIX systems, we have on each of them 2 queue managers running; one QM1 is listening port 1414 and the other QM2 is listening on port 1415.
For some 'political' reason outside the scope of this message, we need to "switch" these port numbers, thus that means QM1 will listen port 1415 and QM2 port 1414.
Can this be achieve simply by adapting the AIX system file /etc/services, or do I need to completely remove/reinstall both queue managers ? In other words, is the port number information stored somewhere within MQSeries configuration files ?

I tested that, and it's working fine ... just stopped both queue managers, adapted /etc/services, HUPed inetd and started the queue managers.

Why do you use the inetd to control the Listener?
We use these commands to start our QMGR.
| Code: |
strmqm MQXT5
nohup runmqlsr -t tcp -p 1414 -m MQXT5 &
echo "-> WebSphere MQ MQListener is PID:$! "
nohup runmqchi -m MQXT5 -q SYSTEM.CHANNEL.INITQ &
echo "-> WebSphere MQ ChannelInitiator is PID:$! "
strmqcsv MQXT5 |

BTW, hopfe_de, why do you start chanel initiator separately ?
It supposed to start automatically, doesn't it ?

| We have up to 4 Qmgrs on a AIX, and with these scripts we can easy start them on different ports. |

After changing the /etc/services file you must run
#refresh -s inetd to restart the services with the new configuration

Two other points.
I hope that theses Queue Managers were not part of a Cluster. If so, then it's a little more complicated.
And, you did remember to go around every 'other' Queue Manager that connects to these two to change the Connection values. 
Cheers,
