Hi to everyone,
Since 10 days we are experiencing problems with our MQS, who have been working properly for a long time.
In particular we see in the event log (Windows 2003 server) AMQ9213 errors generated without following any pattern.
After reviewing the documentation we can't found a reason for that error. Has anybody encountered this problem?
PD: return code 0(X'0')
Regards, |

Not enough information to offer any help. Are there any FDC files matching the date/time of the occurrence? What WMQ version and Fix/RefreshPack are you using? Any changes to the server and/or network?

No FDC files founded, but I hope it's possible to generate manually with:
amqldbgn -p PID (on windows) ??????
Also we're using WMQ 6.0.0 without any Fix/Refreshpack (really i don't know how can i check Fix/refreshpack version)
About server changes, only Windows 2003 server updates. (last one on 25th of september).
About network one change in the firewall but theorically not affect on our lan.
How can I proceed?
thanks in advance, |

If there's none generated, I doubt forcing one will tell you much.

If it really is the base WMQv6 you should apply maintenance

Before or after your problems started? If just before it's a clue.

I've been given that theory by network people as well. Check if their theory holds in practice.

Check with the network people again. Test the network with non-WMQ tools. Check if the server update could be causing the problem. Check if you are on the base WMQv6 and apply maintenance if so.

Where did you see the AMQ9213 errors? What is the entire text of the error message? AMQ9213 is often accompanied by an FDC. Where did you look?
Are you saying that all the qmgrs on the server can no longer successfully start channels to their peer qmgrs?
Or, are you saying that only one of the qmgrs is experiencing this?
What errors are logged on the qmgr at the other end of the network?

I see the AMQ9213 in the windows event register and in the AMQ*.log from the qmgr
entire text following (in spanish ...):
05/10/2009 00:11:14 - Process(5388.638) User(MUSR_MQADMIN) Program(amqrmppa.exe)
AMQ9213: Se ha producido un error de comunicaciones en TCP/IP.
EXPLICACIÓN:
Se ha producido un error inesperado en las comunicaciones.
ACCIÓN:
El código de retorno de la llamada TCP/IP(recv) [TIMEOUT] 360 seconds ha sido
el 0 (X'0'). Anote estos valores y póngase en contacto con el administrador de
sistemas.

I'm looking for FDC files on install directory .... and nothing ..

Randomly it seems to be a tcp problem (but only MQS registers it) ..... then when the client tries to connect again, appears AMQ9213 ...

we're working with one main qmgr on every server.
when the amq9213 appears, it seems like recv is hang out ....
on the qmgr 9213, 9999, 9002
on the other side, 9202, 9999, 9002 and 9558
Any clue?

I'm assuming that these are AMQ errors, yes?
AMQ9202: remote host not available.
AMQ9558: Remote Channel is not currently available
Are these channels secured by SSL?
No FDCs on either qmgr?
When this error occurs, can you do a tcp ping from sender to receiver?

My poor Spanish tells me this might be a Time Out error....
Make sure using
| Code: |
| telnet <destinationqmgrhost> <destinationqmgrport> |
that the destination qmgr can be reached (no firewall stopping you)...
If this is the case, make sure that the channels do not think they are running when they are not. (side effect of network maintenance sometimes).
Force stop the sender and receiver channels. Try and restart the sender channel. If it goes in retry check the qmgr logs on both sides.
Have fun

Update KB948496 set TCPA, TCPChimney and RSS to 0 in regedit.
Update KB971032 is related to MQ protocol.
Do you think TCPA and others TCP params could affect?
Thanks, |

Have you looked in Program Files\IBM\WebSphere MQ\errors and Program Files\IBM\WebSphere MQ\qmgrs\qmname\errors? |

Hi,
we are often faced with AMQ9213 and recv TIMEOUT. I can't remember ever have seen a FDC in this context.
It was always a network error. And if a channel is stopped because of a network timeout there is no reason to write a FDC, it's normal bahavior, not a mq failure. May be there are AMQ9213 with FDC, too. But if there is no FDC, I'm quite sure it's the network (firewall, hardware, tcp-stack, system is to busy on one end, high network load, ...).
No problems with other applications don't prove anything.
BTW:
Analysing problems on a 6.0.0.0 version is wasting time. Install 6.0.2.7 and recreate the queuemanager to avoid other problems in the future.
(Your network problem will probably not be fixed by this)

Hi to everyone,
Finally all of you were on the right, and the error AMQ9213 was generated by a modification of the firewall.
Thank you all for your help and fast answer.
