Oracle Process using beq (bequeath protocol)

[Sureshy]

Hi Friends..

I have 2 questions :

1)

I have noticed many user processes which are spawned as soon as an oacle instance is started. The command looks something like this :

oracle (DESCRIPTION=(LOCAL=YES)(ADRESS=(PROTOCOL=beq).

I do not have beq protocol specified in tnsnames.
BEQ protocol is specified in snmp.ro.ora.

Do these processes have something to do with the subagent.
A truss -p pid shows the process performing a lot of read/write. Does anyone know what it is, why it is there, what it is doing ?

2)

also.. can increasing SGA have a negative affect on performance - if so in what circumstances?

Thanks

Suresh

Increasing the SGA may cause swapping and paging in your host machine processes. This will negatively impact Oracle performance.

A bequeath connection is another way of saying dedicated connection.
