And it's not a default; rather, it's an initial value, which is of no value if the application sets the value in the MQMD to anything other than _AS_QDEF.

Short book.
I am working on "The Art Of Trout:What Sun Tzu Left Out" which I hope the publishers will like.
I plan to team it with an illustrated self-help piece: "Trout:To Eat Or To Whack?".

I'm not sure he'd pass the necessary originality requirements...

For the record, which process is this? I've never heard of it. All I know about is the workload balancer, which doesn't hold state that I'm aware of.  |
Ok, I have called the detection in broken channel communication and update the state in the repositories in this way. |

In some, but not all of your narrative, you say "Check status > S1: SCTQ empty"

Empty means no message is the queue when browsing with MQ Explorer.

I'm thinking that it's your application that, for whatever reason, did not commit, and therefore the message(s) were backed out of the SCTQ. |
Its also the exact same behavior when using a JMS Client, MQ Exploere or amqsput.exe - do you have a preferred test client ? |

That's not empty. Any message not eligible to be read (e.g. put but not committed) will not show up. This is where your message is "disappearing", and why we've been banging on about empty queues and commits for the length of this post.
An empty queue is a queue with a depth of zero.

Ok, after getting all the Hint & Tips from you I started some more test on it. Still I can see/discover my message which should have been sent out the the off-line qmgr - any commands issued on any transmission or dead letter queue return queue depth = 0. But being some more patient (really absolute mega patient) the inflight message of the corrupted channel appears in its originally targeted qmgr queue - hurra.
So thank you all, for your patient with me and lesson learned: even if you cant see or count the message in the obvious places it might be still around! |

Well put.

Another lesson I hope you've taken from this: a WMQ cluster is not designed as an HA solution. Using it as such has issues.
For instance when the inflight message is for a $4m transaction and the business doesn't fancy being really absolutely mega patient waiting for it to process.
Nothing new in that statement. Been said often in here. But glad you got understanding.
