Hello all,
I'm running some performance tests and need to know how does the
database connections work. Are they open when we start OpenSER and are
kept open for each process or they just open before a query and closed
afterwards? Does anyone know where I can find such info?
most of them are open at
startup and kept alive for runtime duration,
being closed at shutdown. There is a connection pool per process, so
there is only one connection to a database from the same process.
In vary rare occasions, when Kamailio is not processing SIP traffic but
MI/RPC commands, it may happen to have the connection open, query done
and then connection closed.
If you want to learn more about DB API, then look at devel guide:
http://www.asipto.com/pub/kamailio-devel-guide/#c09database
and sources in lib/srdb1 (the one mainly used in kamailio (thus former
openser) modules).
Cheers,
Daniel
