Hi All,
I am using MQV5.3 CSD05 on the AIX O/S.
I have Distributed Architecture in the project.
It is known fact that the Listener and command server do not come in running status as we restart or reboot the AIX machine.
We need to start the Listener in this case.
I want to start the Listener and Command server automatically at the time of reboot/restart
Queries :
1) Is there any tested and proved way to do this if i want to use MQ
Listeners ?
2) Is this problem discussed in any IBM manuals?
3) What are the performance issues related of Using the TCP/IP listeners
(inetd.conf file) ? I am expecting at the max 200 active channels at
any point of time
Waiting for Reply 
Thanks in advance !!!! |

1. Start your qmgr in a script. After strmqm returns, run strmqcsv. Note that you do not need to have a qmgr running to have the listener running, and the listener does not need to be stopped when the qmgr does. So, you can start the listener independently of starting the qmgr.
2. What problem? It is a fact, not a problem. The listener is not started automatically because there is a choice on UNIX, either the WMQ listener or the UNIX listener inetd. The command server is not started automatically because it is a potential security exposure to have the command server running with unsecured channels.
3. The performance impact is that each RCVR or SVRCONN channel runs as a process, amqcrsta, instead of a thread in amqrmppa. |

Thanks Nigelg,
I am pretty naive for the AIX system .Can you please point out the location, where I can put the scripts to make them run at the time of reboot. |

| For the listener, you could also define a inetd service which will start automatically when the inetd daemon is started. |
