Hello all,
Is it possible to configure Kamailio to reply to a request with a 503 if it
cannot connect to a necessary database for the operation?
I.e. Kamailio cannot connect to the database, when a REGISTER comes in and
userloc can't find the credentials (due to DB failure), respond with a 503.
The requesting endpoint can then fail over properly. The same behaviour would
be desired for other modules as well, i.e. aliasdb.
I noticed using 3.1.5 that it simply does not authorize the user.
I have been thinking about this as well. We could implement a db_ping function
so we could test in the routing script before
calling functions that use the DB. It's harder with stuff that happens in the
background, like ACC and SIPTRACE. I don't know
what happens with them if the database fails.
one option would be to set a config env variable, like db_error, which
is set by the db modules on error. Then can be checked in the config and
act accordingly. This will require touching the db modules.
Alternative is to propagate some return codes up to config file, but
this will require changes in all modules interacting with database,
including the db modules.
Cheers,
Daniel
