| I was wondering what additional configuration one has to make to have multiple qmanagers on single SUN machine. I am concerned about the entree in the /etc/inetd.conf /opt/mqm/bin/amqcrsta amqcrsta -m <1stqmanager>how do i add the second one? TIA Ilya |

The line in /etc/inetd.conf contains the QMGR_NAME as a parameter so all you
do is copy that line and change the queue manager name in both places.
also in the /etc/services file you need to pick a new port number.
QMGR_NAME 1415/tcp
Also restart inetd after these changes

| Tnaks for a quick responce. One more question: What if I want to bind each Qmanager to a specific Virtual IP address. For example: I do not want to use different ports, rather I would listen on the same port (1414) but ont he differnt ip on the same machine. How can this be accomplished? What can I use instead of /etc/services entree? Or how can this entree be modified? TIA Ilya |

A solution is to configure the listener to listen only on a single ip-address. This can be done by editing the section TCP in file qm.ini
[TCP]
PORT=n
IPADDR=x.x.x.x or hostname |

If the /etc/inetd.conf trick I suggested works on Sun you will end up with
2 lines
64.101.101.11:QMGR_A stream tcp nowait mqm /opt/mqm/bin/amqcrsta -m QMGR_A
64.101.222.22:QMGR_B stream tcp nowait mqm /opt/mqm/bin/amqcrsta -m QMGR_B
also /etc/services
QMGR_A 1414/tcp
QMGR_B 1414/tcp
Iam not sure this will work on Sun.

Sorry Jeff, this will not work. You can only have one application (Unix process) listening on one TCP/IP socket port. If you try and start a second app against the same port it will get a socket bind error and not work.

Well inetd is the one binding to the ports, so it's not 2 applications trying to bind to the port also there are 2 seperate IP Address. Linux
is able to specify listening to one IP only, so it might be possible. I tend to agree it probably wont work, but it is an intresting expierment

thanks to all who replied what is the exect syntax for the this entreees in the qm.ini file. I get some errors. please help: A solution is to configure the listener to listen only on a single ip-address. This can be done by editing the section TCP in file

Just an FYI on LINUX!! This works
I setup 2 virtual IPs on the loop back device
and added the following to my inetd.conf
128.0.0.1:telnet1 stream tcp nowait root /usr/sbin/tcpd in.telnetd
129.0.0.1:telnet2 stream tcp nowait root /usr/sbin/tcpd in.ftpd
added the following to my services file
telnet1 1414/tcp
telnet2 1414/tcp
restarted inetd
when I issue a telnet to 128.0.0.1 1414 I get telnet session
when I issue a telnet to 129.0.0.1 1414 I get a ftp session
Now if the inetd works the same on Sun then this type of setup will allow you
to listen on 1414 for more than 1 queue manager if you have the seperate virtual IP Address

| I was just able to test the configuration with IPADDR. This feature is documented in the book IBM MQ Series Intercommunication (Appendix C). If I set this feature the listener did not start. The errormessage is "AMQ9224: Unexpected token detected.". |
