Hi Daniel,

 

So the solution is basically to wait for the DB APIv1 implementation in prefix_route?

Subject: Re: [SR-Users] prefix_route and db_cluster not working

 

Hello,

the prefix_route module was written by SER guys, when Kamailio and SER were split projects, and it uses what we refer as DB APIv2 (specific for ser project), while db_cluster implements DB APIv1 (specific for kamailio project).

From my point of view, it will be easier to add support for DB APIv1 in prefix_route module than implementing DB APIv2 in db_cluster. I think there very few modules implementing DB APIv2 at this moment (maybe around 5) and perhaps they should get support for DB APIv1.

Cheers,
Daniel

Hi,

 

I have an issue when I am unable to get prefix_route to work together with db_cluster. If I set the db_url manually it works great, pointing it to a specific database. However we need the redundancy for this module.

 

Dispatcher uses the same cluster without any issues.

 

The following are my configuration sets:

 

# DB CLUSTER (db_cluster.inc)

loadmodule "db_cluster.so"

 

modparam("db_cluster", "connection", "KAMDB01=>mysql://kamailio:password123@192.168.55.10/kamailio")

modparam("db_cluster", "connection", "KAMDB02=>mysql://kamailio:password123@192.168.55.11/kamailio")

 

modparam("db_cluster", "cluster", "AccCluster=>KAMDB02=9s9s;KAMDB01=4s4s")

modparam("db_cluster", "cluster", "Settings=>KAMDB02=9s9s;KAMDB01=4s4s")

 

# KAMAILIO.CFG (kamailio.cfg)

# PREFIX ROUTE MODPARAM

 

loadmodule "prefix_route.so"

include_file "db_cluster.inc"

modparam("prefix_route", "db_url", "cluster://Settings")

modparam("prefix_route", "db_table", "prefix_route")

modparam("prefix_route", "exit", 1)

 

 

Syslog output:
