Hello,
I try to start a QMGR on a backup server without reset channels on AIX. So on server A :
- I stopped channels receiver
- I saved the SYSTEM.CHANNEL.SYNCQ
- I stopped the QMGR
On server B, I created the same QMGR listened same port with same objects and :
- I restore messages in SYSTEM.CHANNEL.SYNCQ from server A
- I sent test messages to tests all channels.
All channels are in state retrying because the sequence number is wrong.
Did I forget something ?
Thanks for your help.[/list] |

Possibly you forgot to reset the sequence numbers on the channels?
Just a guess.
I'd also advise against copying the contents of any SYSTEM queue from one queue manager to another. Or indeed touching the SYSTEM queues. It only leads to problems.

| I can't reset all channels because there are QMGRs in Asia, NY ... and I can't access to servers |

I apologise for my loose terminolgy - when I said "you", I meant "somebody in your organisation".
If you can't access the servers, then you need to contact whoever is administering them.

I thought that by restoring the contents of the SYSTEM.CHANNEL.SYNQ to another QMGR, the sequence numbers were preserved.*
Indeed, we have more than 250 channels, it is difficult to request to our partners to make a reset on each of them channels sender. |

Really? News to me, but maybe it's another vindication of my signature.

| syncq on distributed platforms does not hold sequence numbers - at least, not since version 5.0-ish |
