Emile, Rebecca,
I have not changed the expiry attribute, I mean that I am not explicitly
changing the expiry attribute of the message in my application program. I
think the default is unlimited expiry time.
Do I have to set it to something so that messages remain ?
Plus, today we changed a few attributes of the transmission queue. We set
the trigger type to F and also set the inititation queue to
SYSTEM.CHANNEL.INITQ so that once a message is received in the transmission
queue the Channel is started from its inactive state.
But still there is some problem when we stop and restart a channel. Messages
just disappear. They are not found on the DLQ either.
Paul,
Can you explain what you mean by 'trace the channel' ?
Regards
Sundari

If the channel was stopped manually, it must be started before messages
will flow between systems.
Yes, persistence is used when the QMGR needs to recover the queue.
If the messages had an expiry time, the QMGR will discard them when the
expiry time is reached.
Do you have default DLQ assigned to the QMGR?

No channel triggering. We stopped the channel for some other
purpose(test)
and in the meanwhile we had placed a number of messages in the XMITQ.
When
we noticed the problem we re-started the channel and found that the
messages
were not there. The messages are not persistant.
I thought message persistance was required only when the queue manager
itself goes down. Correct me if I am wrong. We are checking the DLQ.
Queue was inactive not stopped.

Three questions:
1. Are you using channel triggering and why is the channel in a stopped
state?
2. Are your messages persistant and do you interrogate the expiry option
on the message?
3. When you say LOST, are the message gone, have you checked the DLQ?

Subject: Channel problem
Hi
We are writing COBOL API that runs on OS/390 and places messages on
queues
running on AIX. I had mailed the problem to the listers already
yesterday
and now I have the problem much more well defined. Hope someone can
help.
When the sender channel is running and my application program places
messages in the queue all goes fine.
When the sender channel is stopped and my application program places
messages all the messages get accumulated in the XMITQ.
When I restart the sender channel the first two messages alone are
logged
into the remote queue. The rest of the messages are lost.
Actually someone over here suggested that the message ids of the rest of
the
messages are lost and that is why the messages are lost and they said
the MQ
administrator should be able to log message ids into some buffer area if
the
channel is not running. Do you have any more suggestions on this ?
Regards
Sundari
