Re: [SR-Users] Database errors with usrloc db_mode=1 and dmq_usrloc

Hello, the error message: Feb 21 00:11:25 csbc02 csbc[13916]: ERROR: <core> [db.c:481]: db_use_table(): invalid parameter value 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? * https://github.com/kamailio/kamailio/commit/3843ae18599bfc1806ccb62df44bbc8… Cheers, Daniel On 21.02.20 22:40, Joel Serrano wrote: 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.

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): Feb 21 00:11:25 csbc02 csbc[13916]: ERROR: <core> [db.c:481]: db_use_table(): invalid parameter value Feb 21 00:11:25 csbc02 csbc[13916]: ERROR: usrloc [ucontact.c:1136]: db_update_ucontact_ruid(): sql use_table failed Feb 21 00:11:25 csbc02 csbc[13916]: ERROR: usrloc [ucontact.c:1657]: update_contact_db(): failed to update database I added debug logs to see if I could understand the reason: Feb 21 14:38:34 csbc02 csbc[30796]: DEBUG: dmq_usrloc [usrloc_sync.c:478]: usrloc_dmq_handle_msg(): dmq message received from sip:usrloc@10.2.1.181:5050 Feb 21 14:38:34 csbc02 csbc[30796]: DEBUG: dmq_usrloc [usrloc_sync.c:423]: usrloc_dmq_execute_action(): Received DMQ_UPDATE.
