Hi Harry,
I admit ignorance. Networking was never my strong point. IN fact sometimes I wonder if I still have one.
Thanks for your response.

Afternoon Lisa,
I thought that BEQ and (for example) IPC protocols both used the listener to
spawn a server-side process. The difference is in the protocol used in the
communication between the remote and local processes. IPC uses Unix Domain
Sockets to communicate between the client-side and server-side processes,
where BEQ uses Unix pipes. I had assumed that this was why BEQ connections
had to be local. This is the view expounded in Note: 1014940.6. If I've got
it wrong, it'd be nice to know. Any comments, Gurus?

Thanks,

Hi Deepak
Here's what the doco says
The Bequeath protocol <glossary.htm> enables clients that exist on the same
machine as the server to retrieve information from the database without
using the listener. The Bequeath protocol internally spawns a dedicated
server process for each client applications. In a sense, it does the same
operation that a remote network listener does for your connection, yet
locally.
Bequeath is used for local connections where an Oracle client application,
such as SQL*Plus, communicates with an Oracle server running on the same
machine
Tell me if I'm wrong but here's my take on it: When I connect from my pc,
there's a process on my PC and there's a corresponding process on the
database, say on a Unix server. Though the connection was initiated
remotely, the process itself on the db server is still a local process that
exists to communicate with the database.
Am I wrong? If so let me know.

        hey lisa
        Thats what i was temted to reply as well {lol} .. but
if you look closely .. both her conn are bequeth .. i
was under the impression that bequeth was used only
for local and not remote .. thats why we chose beq
over tcp for db's that resided in same box for
performance reasons .. or so i thought until now ;)
        thoughts ..?
        Thx
Deepak
