I have the following scenario that is bugging us. We are connecting a Unix installation running MQ 5.3 under WBI to a Linus 6.0 standalone version commnicating over vpn. Everything works fine, except we have to start the channels manually (in each direction) to get the data to flow out of the XMIT queues. Once we start the channels (from an inactive status) the messages flow and continue to flow for the duration the channel stays active. I have the same AIX system communicating with multiple MQ instances and this is the only one giving us problems. I've had other people verify the INITQ, Channel, and XMIT configurations and noone can find anything wrong on the UNIX server. I've also verified the config on the LINUX server side. This happens regardless if I were to drop a test message or have one sent via a WBI connector.
Any suggestions or known issues? |

I think you should search the forum or the docs for concept of 'triggering channel'.

| As I stated the other connections work fine, I understand the concepts of triggering. |

I'm glad you understand the concept of triggering...
Ok, my mistake, I did not notice that you've already triggered the channels...but I would still ask you to search, there are topics here with ppl having the same issue...reading about your issue will be easy for you to solve the problem, rather than first explaining it to us and our suggesting possible solutions...finally if nothing works, we can still sit with it...
Regards. |

Are there uncommited messages on the XMITQ?

| Yes, they will sit in the XMIT queue on both sides until we bounce the channels, and we have different channels defined, one into my system, one out of my system. |

I don't mean "are there messages on the XMITQ", I mean are there messages in syncpoint that are not committed that are on the XMITQ?
If there are, this could impact channel triggering.

Is the channel initiator running? On UNIX it is the process runmqchi. It is possible for it not to be started at qmgr startup by setting a qm.ini parameter Chinit=NO, or by starting the qmgr with the flag -ns.

that doesn't mean there are not uncommitted messages on the XMITQ.
You can get-enable the XMITQ, and compare the qdepth to the number of messages you can see when you browse the queue.

There are no error messages in the error logs on either qmgr?
There is at least one process that has SYSTEM.CHANNEL.INITQ open for Input?
