Home -> Community -> Mailing Lists -> Oracle-L -> RE: Connection question?
Harry,
I am not sure that BEQ connections use the standard listener at all. In fact on VMS systems you cannot make an internal connection if the bequeath listener is not started (BEQLSNR START|STOP|STATUS). Once you start that listener then you can connect internal even if the normal listener LSNRCTL START|STOP|STATUS) is not running.
I think you are probably correct in what you say but the term listener is used slightly inaccurately.

Subject: RE: Connection question?
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
