We've installed IBM WebSphere MQ 7.0 in a Win 7 Professional 64bit box, and created a q manager and a server-connection channel via the WebSphere MQ Explorer.
However the q manager cannot be connected (MQCONNX ended with reason code 2538).
Command:
amqscnxc -x 127.0.0.1(1400) -c SVRCONN QM_01
Have checked through the following:
1) WebSphere MQ Explorere -> QM_01 -> Advanced > Listeners > Port 1400 > Listener status = running
2) telnet 127.0.0.1 1400
returns a blank screen indicating that port 1400 is opened.
3) netstat -a listed
Proto Local Address Foreign Address State
TCP 0.0.0.0:1400 TEST:0 LISTENING
What else is amiss here?
Please help .............................
Thanks,
Ben |

What user id did you use to connect?
What is the qmgr's service id?
How did you start the qmgr?
I found that those problems tend to disappear when the qmgr is started with the -si flag...

* We only fill-in the MAC user ID in the server-connection channel. Is that the one?
* Please excuse me ... where can the qmgr's service id be found?
* The qmgr is started via WebSphere MQ Explorer -> qmgr > right-click -> Start -> Start as created
* Could you show a sample on how to start the qmgr with the -si flag?
Thanks,
Ben

did you try the telnet to the port? Just to make sure there is no firewall blocking you...

Benzz -
MQRC 2538 is "MQRC_HOST_NOT_AVAILBLE".
This means that it's not able to find 127.0.0.1, or that you need to put quotes around '127.0.0.1(1400)' or that you do not have a working network adapter. |

You're right, I think it's the missing quotes... if it were the network adapter the telnet should not have been successful.

* Tried with quotes around (with and without firewall):
amqscnxc -x '127.0.0.1(1400)' -c SVRCONN QM_01
Still can't connect, but this time 2539 mqrc_channel_config_error.
SVRCONN is a server-connection channel created for qmgr 'QM_01'.
* 127.0.0.1 is ping-able.
* Also tried without firewall:
amqscnxc -x 127.0.0.1(1400) -c SVRCONN QM_01
2538 mqrc_host_not_available as before.
The log file in the errors directory shown:
AMQ6125: An internal WebSphere MQ error has occurred.
AMQ6183: An internal WebSphere MQ error has occurred.
AMQ9208: Error on receive from host 127.0.0.1(1400)
EXPLANATION:
An error occurred receiving data from 127.0.0.1(1400) over TCP/IP. This may be due to a communications failure.
ACTION:
The return code from the TCP/IP recv() call was 10054 (X'2746'). Record these values and tell the systems administrator.
What else need to be checked?
Thanks for all your suggestions,
Ben

TCP/IP 10054 : WSAECONNRESET -- Connection reset by peer. This occurs when an established connection is shut down for some reason by the remote computer.
Are you absolutely certain you have turned off the firewall?

* Tried again turning off the firewall:
Windows Firewall -> Turns off window firewall (for both private and public network) -> click ok
amqscnxc -x 127.0.0.1(1400) -c SVRCONN QM_01
Still the same error:
2538 mqrc_host_not_available
AMQ9208: Error on receive from host 127.0.0.1(1400).
EXPLANATION:
An error occurred receiving data from 127.0.0.1(1400) over TCP/IP. This may be due to a communications failure.
ACTION:
The return code from the TCP/IP recv() call was 10054 (X'2746'). Record these values and tell the systems administrator.
Do I have to 'allow a program or feature through Windows Firewall'? (shouldn't be if the firewall is turned off, right?)
Thanks,
Ben

Can you please dump the definition of your SVRCONN channel?

How would you dump the definition of the channel? Is it from the WebSphere MQ Explorer or a command to run?

runmqsc <QM NAME>
dis chl(<SVRCONN NAME>)
end
Copy and paste the result of the above - and I suggest diving into the manual in regard to command lines because one day you may not have a GUI available.
