mqrc 2079, Published messages not reaching to destination
I have a clustered topic on qmgr QM1DEV01 and subscription and target queues are created on qmgr QM1PIN01 .
I found that large size msg(less than 100 mb) are not able to reach to the destination.
I have updated maxmsgl param for the qmgr, target queue, transmit queue, inter.pub queue and respective cluster receiver channel.
the msg lands on dead letter queue of qmgr A.
the dead letter queue header just mentions 2079 and
QM1DEV01 and QM1DEV02 have same configuration and are in same cluster as QM1PIN01
MQGET of message number 1, CompCode:1 Reason:2079

Thanks for your response
yeah but currently there is not application reading from the queue. I have another qmgr configuration which is able to receive this msg (old config) in the same cluster.
the only difference is the qmgr has local subscription on QM1DEV01 and clustered queues as destination and my config has clustered topics and sub and destination queues on the QM1PIN01.
I believe the issue is with one of the queue . channel but since I have changed the qmgr, target queue, transmit queue, inter.pub queue and respective cluster receiver channel. still the error persists. again the path from QM1DEV01 to QM1PIN01 is through cluster as the published msgs on this topic will be published all clustered qmgrs (due to clustered topic)
. When an application subscribes to a topic that resolves to a clustered topic, IBM? WebSphere? MQ creates a proxy subscription and sends it directly from the queue manager where the subscription is created, to all the other members of the cluster.
https://www.ibm.com/docs/en/ibm-mq/7.5?topic=clusters-cluster-topics
the mqget call is internal to qmgr (and not from any external application yet) |

Sorry, I didn't read to the bottom of your post.
Amqrmppa is the receiver message channel agent, attempting to put to queue SYSTEM.INTER.QMGR.PUBS. What is the max message length for that queue?

Error before updating cluster transmit queue, Inter Pub and cluster channel max msg length
DLH ........SYSTEM.INTER.QMGR.PUBS QM1DEV02 "...R... ....amqrmppa
post changes also remains same.
only change - if I update Inter Pub queue length and cluster channel length 4mb then it mentions destination queue name in DLH
DLH ........Destination.FROM_APP.DATA_QUEUE "...R... ....amqrmppa |

So, it?s not the EXACT same error.
What VRMF of IBM MQ queue manager?
Have you opened a PMR with IBM support?

Other than posting here, what have you done?

It would help us help you if you provided more detail. For example, exactly what size messages result in the error? 50k, 100k, 2meg, 16meg, 50meg?

Name: IBM MQ
Version: 9.3.0.0
Level: p930-L220606
and no PMR is opened yet as I wanted to confirm that , if an update to maxmsgleng for some queue or channel is missing.
I have tried various combination of update to system queues and channel for maxmsg length.
the same configuration works for smaller messages
also if I create local sub (QM1dev1) and destination as clustered queue (QM1PIN01 that config also works.
so only config with clustered topic with sub and destination on another qmgr does not work with large msgs.
I wil raise PMR if I don't find suitable answer here

Don't wait. Open a PMR now.
