Hi Carsten, from my experience Usrloc + DMQ works very well, rare replication race conditions are insignificant since the state is quite volatile anyway.
However you can only have that many nodes, great for clustering.

Hi,
I wanted to quickly ask the group about experiences with DMQ and Usrloc/Dialog.
I don't expect any issues when choosing such an approach, especially since we would have re-transmits for a message (fr_timer = 30 seconds) if we did not receive any answers or scenarios alike. So I assume, having short "outages" (less than 30 seconds) for the communication is just fine.
So far I used DMQ in a non-IMS setup for synchronizing usrloc with ~15k Subscribers and it worked really well.
One concern brought up (not by me) was, that synchronizing usrloc with DMQ might not be reliable at scale. I would also love to understand how to treat situations when the communication is lost for a longer period of time (e.g. if the communication between nodes is lost for 5 minutes?).
Can anyone share some real-life experiences?
Thanks, Carsten
