Hello,
ok, thanks fr testing, I pushed a commit for it in master and 5.3
branches for now.
Regarding the server id, I haven't implemented the dmq replication for
location records and I guess that the main scope was to work independent
database servers for a geo-distributed deployment, so inserting all
records was considered necessary.
If you want some other behaviour, describe it in a feature request and
it can be implemented.
Cheers,
Daniel

Hi Daniel,
After changing PROC_NOCHLDINIT for PROC_RPC in dmq.c no more errors!

Having set modparam("usrloc", "server_id_filter", 1), shouldn't
the
node receiving locations records via DMQ *not* update the database (as
the server_id param won't match with the one in the DMQ request)?
Thanks again!
Joel.

Hello,
the database connection is not initialized for that process
based on the c code, as it is started with no child init
callback, where the db connection is usually created:
src/modules/dmq/dmq.c
283: newpid = fork_process(PROC_NOCHLDINIT, "DMQ
WORKER", 0);
Can you try with PROC_RPC instead of PROC_NOCHLDINIT and see
if works ok?
Cheers,
Daniel

Ok so my findings so far:
1- db_mode=2 --> No errors.
2- db_mode=1 --> The reported error.
3- modparam("usrloc", "server_id_filter", 1) -->
Irrelevant, errors happen with or without it on db_mode=1.
Anything else I can try in order to find out what is
happening? My next step was to enable mysql logs or
capture traffic and see what exactly is Kam sending...
Let me know your thoughts.
Thanks,
Joel.

Hi Henning,
Every time I register, NodeA says OK, sends location
by DMQ to NodeB, nodeB logs the error.
I tried moving the VIP from NodeA to NodeB, and the
error stops happening on NodeA, and starts happening
on NodeB.
I did not see this happening with db_mode=2, and I
*think* it started happening when I enabled the
server_id related params? I'm not 100% sure of this
so I'm going to try some different combinations to
see if I can narrow it down a little and provide
more accurate details for you guys to find the issue.
I'll report back shortly...
Thanks!
Joel.

So the table name seems to be ok - this function
also log this error if the DB connection handle

this happens.

Hello,
I have a setup with 2 kamailio in
active/idle, locations are shared via
dmq_usrloc, but database is also used as
a cache where other systems can access
and query "real-time" data.
The config we have is:
# ----- usrloc params -----
modparam("usrloc", "db_url", DBURL)
modparam("usrloc", "db_mode", 1)
modparam("usrloc", "db_load", 0)
modparam("usrloc", "db_insert_update",
1)
modparam("usrloc", "db_timer_clean", 1)
modparam("usrloc", "server_id_filter",
1)
modparam("usrloc", "timer_procs", 2)
modparam("usrloc", "timer_interval", 60)
# ----- dmq_usrloc params -----
modparam("dmq_usrloc", "enable", 1)
modparam("dmq_usrloc", "sync", 1)
modparam("dmq_usrloc",
"batch_msg_contacts", 50) # 50 contacts
/ message
modparam("dmq_usrloc", "batch_size",
10000) # 10000 contacts / batch
modparam("dmq_usrloc", "batch_usleep",
500000) # one batch every 500ms
With this setup, we assume:
1- almost real-time updated location
info in the database.
2- as long as one of the two Kam is up,
location information will not be lost
(as they will sync with each other via DMQ)
3- if both servers go down, locations
are lost (as they will not reload from
database on startup).
Our tests work well with the above
config, with one exception, on the idle
node, we see a lot of (only happens on
the node receiving location via dmq):
