As I said earlier, you probably need to do very careful manual edits on the MRM database.

Wich tools can be used?

Whatever tools your database supplies, or whatever tools you have that can talk to a database.

Hello

I've looked in all tables of the MQSIMRDB and MQSICMDB once again with no result, it is clear that the ghost messageset is not defined there, it must be another file in wich messageset are stored before they go to the PROJECT table of the MQSIMRDB. Sadly there's absolutely no literature about it.

Hello


I'm on the suspcion that the missing messageset is stored in this queue:

SYSTEM.CLUSTER.REPOSITORY.QUEUE

There's only one message there, i've checked all the tables on the two databases plus all the files on the MRM folder (this is windows) and there's no trace of messageset, so it must be there, awaiting for it's validation.

This command let's you display the content of a queue:

amqsbcg QueueName QManager

But it does not parse it in a human readable format.
How can i retrieve the content in that queue without emtying out it?

Given the case it's what i'm looking for, how on earth can i erase it?
Whith the use of the mqget command?

Thank you all very much for your help

You'd be wrong because that queue is used internally by MQ to maintiain the local state of knowledge about queue managers, queues, and channels in the MQ cluster.

If the MQ messages are perisistent and haven't expired, they have either:
- been consumed by an application
- on an application queue
- on a transmission queue (including system.cluster.transmit.queue)
- on a dead letter queue.
