I have a scheduled job to Stop and Start the MQ Manager to clear unwanted messages lying in the queue. This job runs everyday in the morning.
The jobs been running as expected for the last 6 odd months, until recently when the MQ Sender Channel started going inactive after the MQ Manager was Stopped/Started. I have to manaully start the Sender Channel for the messages to bein flowing.
An idea what might be causing this? |

Check the triggering settings on the XMITQ for that channel...and why stop/start the queue manager to clear messages in which queue?

This is a very odd thing to want to do, or need to do. There are a number of better solutions, including designing your system so unwanted messages don't pile up in the first place. One of the key problems is your method won't clear out unwanted messages set to be persistent!

An inactive channel is not a problem. It's only a problem if it doesn't start running when there's a message to transmit. So is it that messages don't flow, or that the channel status shows as inactive after queue manager start and that's spooked you?

Aside from the poor design that has unwanted messages sitting in queues, or the really poor decision to bounce the queue manager to get rid of them?
Check the triggering settings as my most worthy apprentice points out, also check that the channel initiator is running properly after the bounce.

Must have been me (and others) misinterpreting the really vague statement.....

Glad you got your trigger working though.

So the purpose has changed since your original post? Now that's what I call a fast moving environment! There are very few good purposes that include a queue manager being bounced.
Your next purpose is to discover how the xmitq settings were changed; it's highly unlikely they changed themselves!

Could you suggest how to delete the messages in a queue without stopping the Queue Manager? I have tried different commands but none works since the Queue manager is UP
This MQ is accessed thru CL commands on an AS/400[/img][/code][/quote] |

Any number of support pacs will achieve this, or any of the other methods a search of this forum will turn up.

Most of the commands won't work with the queue manager down! The principle commands don't work while the queue is in use, a limitation the support pacs (and other methods) don't share.
Presumably the reason for the queue manager bounce has now changed again?

| And if you only want your messages to exist for a certain period of time why not set a message expiry? |

Why are the messages going to this queue when you don't even need them?

The correct understanding should be, you were not able to remove messages because some process must had opened the queue object at that instant.

you can CLEAR them, GET them or set the expiry to what ever works for you, stopping the qmgr is really stupid in this case, what will you do with persistent messages ? |
