Hello,<br>
<br>
some information is still cached for some processing in presence
modules. Not sure to what extent you can rely on sharing everything
via database, maybe t_replicate will help for the rest of the cases.<br>
<br>
I think posgress is the db that has the most features needed by
presence modules for sharing, as I remember Peter Dunkley did some
work on this some time ago.<br>
<br>
Cheers,<br>

Thanks for the reply Daniel.<br>
<br>
But is that possible to use the same Presence DB with multiple
Kamailio's ?<br>
If i'll use same postgres DB with multiple Kamailio's - it'll
cause DB locks and other issues ?<br>
<br>
What is the best way to do SUBSCRIBE presence replications - maybe
via SIP (to replicate every handled subscribe msg to all other
presences ?)<br>
And replication via Database must work in db_mode =3 right ? But
it cause low performance due to high database usage - right ?<br>
<br>
<br>
<br>
Thanks in advance.<br>
Kind regards<br>

Hello,<br>
<br>
db_text is not a database engine with a replication mechanism,
it is just some basic DB API emulator using text files as
storage. At runtime all the records are in memory, so no sharing
between instances is possible.<br>
<br>
If you need replication/shared db, go for the well known ones
like mysql or postgres.<br>
<br>
Cheers,<br>

Hi list!<br>
<br>
We use Kamailio 4.2 for presence BLF with DB_TEXT.<br>
And i want to make cluster with a few Kamailio's presences, to
load balance. <br>
<br>
Can you please tell me - is that possible to use same shared
DB_TEXT database with 2 or more Kamailio servers ?<br>

<br>
1-st server will handle SUBSCRIBE's and this Subscribe's
should be accessible also from 2-nd server.<br>
Then PUBLISH'es will be sent to both servers in round robin
algorithm.<br>
Will Kamailio's work with one shared DB or - i'll got some
errors ?<br>
Maybe i'm wrong somewhere ?<br>
<br>
<br>
<br>
<br>
<br>
<br>
Thanks in advance.<br>
Kind regards<br>
