Home -> Community -> Mailing Lists -> Oracle-L -> Re: Multiple listeners question
Why not try increasing SDU, session data unit? Put sdu=15000 e.g. in your
sqlnet.ora. Look at Jonathan Lewis' Web site at
http://www.jlcomp.demon.co.uk/sdu.html. Make sure you use a multiple of 1500,
the default Ethernet frame size. (The default SDU 2048 is rediculous; at least
Oracle should make it 1500 or 3000. The old documentation is wrong in saying
the Ethernet frame size is 1024.)
By the way, I'm under the impression that listeners are not responsible for actually transferring data. The listener only establishes the initial connection. I think it's the shadow process that transmits data. Correct me if I'm wrong.

Hi All !
I forgot to say : that someone told me that if we're going to transfer 25-50 K
of LOBs every query then the network will be very busy .
So we'll need 2 network cards with 2 different IP addresses for the same
physical machine in order to improve network throughput .
This is where the 2 listeners for 2 IPs of the same machine are introduced
