Hi, all
I need to do this scenario:
Web Application Web Application Web Application
| |
|
pgsql server 1 pgsql server 2 pgsql server 3
| |
|
| |
|
| adsl | adsl
| adsl
| |
|
| |
|
-------------------------------------------------------
|
pgsql server ("master")
I need various servers in different locations running exactly some
things, one Web Application and one pgsql server, all synchronizing
with "master" server through unstable adsl connections.
So, If I do one insert in server 1, this data goes to "master" and is
available to other servers, and vice-versa, and if adsl connection
broken, Web Application still working with local server and when
connection is restored both databases are synchronized.
Is this possible?
If it's true, what tools I need?
Thanks in advance to any help, and sorry for my bad English (if
someone can't understand I say, I try to be more clear).
Cheers,
Marco Carvalho
