Hi,
What is the best way to deploy Openser in an HA environment?
If I want to use ldirector, what is the best solution for determining
whether the openser is still alive?
Could someone share with me how it can be done?
Thanks,
Mark

to this one i don't know the answer. there may not even be a single
"best" way, because every proposal i have seen so far have some
weaknesses. so the solution may depend on which weaknesses you consider
less important.
If I want to use ldirector, what is the best solution
for determining
whether the openser is still alive?
i send openser sip requests that exercise all of its components. just
knowing the host or openser processes are alive, do not much good.

Hi Juha,
Thank you for your reply. May I ask how to test whether openser is alive?
Specifically, what tool do you use? If you are also using ldirector, is it
possible to share with me your ldirecor.cf configuration? I am having a bit
of difficulty getting it to work.
Thanks alot for all your help.

i use sipsak. latest monit beta is also capable of testing openser
using sip (at least in a simple way).

i don't use ldirector and don't even know what it is, but if it is a
load balancer that you want to front end your opensers with, then you
have to make sure that it itself is not a single point of failure.
and if your loadbalancer routes sip requests rather that ip requests,
then you need to monitor the loadbalancer using sip requests. checking
that loadbalancer answers to pings or that the loadbalancer process is
alive is not enough.
now i guess you start to see how complicated things really get.
