Hi all,
I have set the adopt MCA property for the QMgr to be "ALL" but I still encountered the situation when the Sender Channel is running but the receiver channel is inactive
both the MQ server is in different server. there are no error in the error log on both side. all the message just trap in the transmission Q and when it is full it goes to the DLQ. Is there a need for the QMgr in the receiver end to set the adopt MCA property to "ALL" too?
Thanks. |

"Inactive" is not a problem unless it doesn't start when a message turns up.

Is the status of the sender channel actually "RUNNING"?
And it's definately pointing at the receiver channel you think it is?

Hi,
Ya it is pointing to the receiver. What I need to do is to stop the channel and reset the channel sequence number and start manually. Is there a need for the receiver QMgr to set the Adopt MCA?
Ya the GUI shows it is running and I use runmqsc to display the status it show running also..
Thanks |

You should not need to reset sequence numbers to restart the channel, unless there's been a failure. This would prevent your message moving quite effectively.

Hi,
I din reset my sequence number at first, the channel cannot start up. The error log states that the channel sequence number is out of syn.
Any ideas?
Thanks |

What is the current state of the sender channel? What is the current state of the receiver channel?
What is the current seq number on the sender? What is the current seq number on the receiver?
What is the connname on the sender? Does it point to the correct hostname and port of the receiver?
Is the Listener on the receiver running?
What errors are listed on the sender qmgr? What errors are listed on the receiver qmgr?

Hi,
The answer below to your question is before I do anything.
What is the current state of the sender channel? What is the current state of the receiver channel?
Ans: The current state of the sender channel is running whereas the receiver Channel is inactive
What is the current seq number on the sender? What is the current seq number on the receiver?
I did not take notice of the seq number on the channel b4 i reset. however, everything is working fine b4 tt.
What is the connname on the sender? Does it point to the correct hostname and port of the receiver?
ya it points to the correct hostname and port.
Is the Listener on the receiver running?
Ya the listener on the receiver is running
What errors are listed on the sender qmgr? What errors are listed on the receiver qmgr?
There are no error at all on both end
btw is there a need to set the Adopt New MCA property on both end? |

Something tells me you are not quite truthful here. Typically if it is a sequence number problem you will see the expected and transmitted sequence number both on the sending qmr and the receiving qmgr's log.
Are you sure this is not a firewall timeout problem? Is your channel correctly going to inactive status after a period of inactivity? If the firewall timeout is less than the channel quiesce/timeout period and the channel has no true activity it could be that the firewall cuts the connection off. Now when the new message hits you have weird behavior as you described. Just recycling the channel (stop + start) should do it, no need for sequence reset.
The right solution of course is to have the channel timeout < firewall timeout.
Enjoy

Hi,
I did see the error on both end on the sequence number issue after I stopped and restarted the sender channel. However before tt when the sender channel is running and receiver channel inactive there is no error.
But when I see thru the error log the receiver administrator sent me today, i realised that their MQ server restarted multiple time a few days ago and tt is when the message got stuck in my transmission queue. But even if that is so shldnt MQ sender channel realise the receiver is down and restarted when the receiver end MQ mgr is up?
Thanks |

Hello,

| Ya the GUI shows it is running and I use runmqsc to display the status it show running also |
I have seen some discrepancy in what the GUI shows and what runmqsc shows in V5.3...
Anyways if the MCA is unable to put a message through then the Message is left on the XMITQ(if DLQ not defined) and the (SDR) channel is stopped...
That's ofcourse is the default behavior...
