Hi Rich,

Thanks for reply. you mean CI and Application server both diffrenet ?

As i undestand that apllication server means where dialog instance resides . am i right.

CI means where message server,enque,gw resides . am i right ?

If yes , in production senarios , how do i install CI and DB seperate servers.

As i undetsand that server A : CI with Oracle client

Server B; DB installation with Oracle server .

Also let mw know where application server ( Dialog instance)resides. On which server ?

Please suggest.

CI is one of the application servers. So lets think of it this way.

                DB SERVER
                    |
                    |
       |------------|--------------|
       |            |              |
    APP SERVER    APP SERVER    APP SERVER
        A           B              C
     CI Resides
       Here              

So we have 1 db server and three app servers running the application, only one of these server can and must be a CI(central instance).

Does this make sense?

Dialog processes can reside on all three appliations servers.
