Hello,

 

if you can not reproduce it with db_mysql, it might be indeed some issue specific related to sqlite. Executing the tests with debug log level should give you more information about the internal database operations, in case you like to look more into it.

 

Cheers,

 

Henning

I cannot reproduce this issue against mysql, so perhaps it is just something related to abstraction and concurrent access with sqlite.

Subject: [SR-Users] DB_CLUSTER failure with carrierroute (and others?)

 

All,

 

I’ve been trying to chase down an issue with db_cluster and permissions in combination with something else, where with my full configuration using the same cluster in multiple modules has failures.  I’ve been trying to create a simplified configuration to consistently reproduce the problem without much success, however I did stumble upon THIS particular problem.  The configuration here works fine as is – avpops uses the cluster URL, and carrierroute uses the direct SQLite URL.  If I define WITH_DBCLUSTER, then carrierroute fails fetching rows using the cluster connection.  Note that AVPOPS is only used as a general test to see if the cluster config works. If I remove references to avpops , carrierroute still fails loading from the cluster URL.   Thoughts?

 

 

 

 

#!KAMAILIO

 

loadmodule "db_sqlite"

loadmodule "pv"

loadmodule "db_cluster"

loadmodule "carrierroute"

loadmodule "avpops"

 

modparam("db_cluster", "connection", "db1=>sqlite:////etc/db.sqlite")

modparam("db_cluster", "cluster", "cl1=>db1=9s9s")

modparam("db_cluster", "inactive_interval", 30)

 

#!ifdef WITH_DBCLUSTER

    modparam("carrierroute", "db_url", "cluster://cl1")

#!else

    modparam("carrierroute", "db_url", "sqlite:////etc/db.sqlite")

#!endif

modparam("carrierroute", "config_source", "db")

 

modparam("avpops", "db_url", "cluster://cl1")

modparam("avpops", "avp_table", "usr_preferences")

 

request_route {

    exit;

}

 

 

Failure log:

 

0(1) ERROR: carrierroute [cr_db.c:345]: load_route_data_db(): Fetching rows failed

0(1) ERROR: carrierroute [cr_data.c:179]: reload_route_data(): could not load routing data
