dmq_usrloc writes to database on other nodes too - sr-users

15 Oct 2021

I have the idea that if you enable dmq_usrloc, the other nodes that receive the usrloc
info, also try to write to database.
We see this by a lot of errors indicating the index violation on postgres.

What is the easiest way to tell Kamailio that it does not need to store the usrloc in
database if the data came through a DMQ message?

Currently I have in my config:
    # DMQ processing
    if(is_method("KDMQ") && $Rp == 5090) {
        dmq_handle_message();
    }

I have understood that no further processing happens then. So is my assumption correct
that my other handling of REGISTER will not be used then?

As in, can you handle this in code that it will only store the register information in
memory? Like this?

# Registration handling
route[REGISTRAR] {
    # If coming from DMQ, don't save to database
    if(dmq_is_from_node()) {
        save("location", "0x01")
    }
}
