Hi,
We have 7.5.0.4 QMGR installed on windows box. I noticed that every initiation queue has two opened input connections. That was strange because for each of initiation queue there was only one trigger monitor running.
After some time I had a problem with transmission queue. There was three process putting on the queue, but when I check them, these process came from receiver channels, which were stopped. This transmission queue is used only by one sender channel so no thing like that should have happened. We could not start sender channel because this xmitq was in use, we could not clear messages (neither clear nor get) from that queue either because queue was in use. No errors in logs, no FDC files. After stopping QMGR with -i flag, we could not start QMGR because there were processes which was still running. After killing them, we still couldn't start QMGR. Reboot fixed the situation, now every initq has only one connection.
Do you know what could case these problems? Maybe there were steps I didn't take but I should?
Thanks |

Put and Get disable the init queue and see who complains.
Review the AMQERR logs and look for FDCs.
Other appropriate and normal MQ troubleshooting procedures.

thanks mqjeff for your reply.
yep, that might be helpful.
Nothing in AMQERR and no FDC generated :/ |

Please explain what your mean by

. Do you mean that these processes had names like amqrmppa? What were the process names exactly?

Please be a bit more precise. Why couldn't you (re)start the qmgr? What errors did you observe?

Sorry for my English.
Xmitq had 3 opened output count. When I check queue status
dis qs(xxx) type(handle) all
these 3 connections was coming from receiver channels.
That was pretty strange because only sender channel should put on transmission queue.
Unfortunately there is nothing in the logs regarding problems with starting Queue Manager. What I remember was message informing about mq processes still runing in the system preventing MQ from starting. Actually this happened to me few times before on different windows machines. That's why I don't like to install MQ on non unix servers.
I don't really understand 2 things:
1. Why each of my initqs had 2 connections from the relevant mq trigger monitor
2. Why xmitq had OPPROCS(3) whily only one sender channel was using it and this connections were not coming from this channel.
Anyway, that must be some internal MQ error because after restart everything went back to normal.
I found only one FDC file:

| Yes, indeed, thanks Inisah. I wonder why I could not find it googling with probe id of FDC. |
