<p>Hello,</p>
<p>the error message:</p>
<p>Feb 21 00:11:25 csbc02 csbc[13916]: ERROR: <core>
[db.c:481]: db_use_table(): invalid parameter value</p>
<p>Is printed if the database table name is not given as parameter
(eg, null or empty). I pushed a patch to usrloc to print the table
in the log message, can you try with latest master (or patch from
next commit) and send again the log messages?</p>
<p> *

<div dir="ltr">Hello,
<div><br>
</div>
<div>
<div>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.</div>
<div><br>
</div>
<div>The config we have is:</div>
<div><br>
</div>
<div># ----- usrloc params -----<br>
modparam("usrloc", "db_url", DBURL)<br>
modparam("usrloc", "db_mode", 1)<br>
modparam("usrloc", "db_load", 0)<br>
modparam("usrloc", "db_insert_update", 1)<br>
modparam("usrloc", "db_timer_clean", 1)<br>
modparam("usrloc", "server_id_filter", 1)<br>
modparam("usrloc", "timer_procs", 2)<br>
modparam("usrloc", "timer_interval", 60)<br>
</div>
<div><br>
</div>
<div># ----- dmq_usrloc params -----<br>
modparam("dmq_usrloc", "enable", 1)<br>
modparam("dmq_usrloc", "sync", 1)<br>
modparam("dmq_usrloc", "batch_msg_contacts", 50) # 50
contacts / message<br>
modparam("dmq_usrloc", "batch_size", 10000) # 10000
contacts / batch<br>
modparam("dmq_usrloc", "batch_usleep", 500000) # one
batch every 500ms<br>
</div>
<div><br>
</div>
<div>With this setup, we assume:</div>
<div><br>
</div>
<div>1- almost real-time updated location info in the
database.</div>
<div>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)</div>
<div>3- if both servers go down, locations are lost (as they
will not reload from database on startup).</div>
<div><br>
</div>
<div>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):</div>

<div>Can anyone help me understand what's the problem? I have
the server_id setting, and the modparam server_id_filter, so
shouldn't the receiving node just ignore any database tasks?</div>
