I have configured two redundant DB sources in my

The DB's are accessed from Kamailio for redundancy pruposes.
Kamailio and the primary DB are on the same hardware node. The secondary
DB is on a remote host.
If Kamailio is up and both MySQL DB's are up, the config works like a
charm. If the primary or the secondary DB becomes unreachable while
Kamailio is up, the config handles the exception and all works well.
Hi JR,
ok, fine so far.
However, if any of the DB servers becomes unreachable
and Kamailio is
restarted, Kamailio can no longer start.
[..]
It seems that the module want to check if its can reach all configured
databases during startup. This is probably required just to make sure that the
user did not make a mistake in the configuration, the DBs are reachable and so
on.
What is the proper way of using multiple database
servers with Kamailio?
May i ask what kind of functionality you miss? I'd think that you need at
least one DB during startup for the server, to be used from sqlops. One
possibility would be to add later a new connection to the module, for example
with a FIFO command when it gets available, but this is not implemented at the
moment.
Instead of handling the outage of DBs in the kamailio server another option
would be to implement a failover setup (heartbeat+drdb for example) on the DB
level, or use a clustering solution (e.g. mysql cluster).
