Hello,
The company where I work is planning to move to NCA (10.7 NCA or 11). We are
wondering some network features that we need to consider in order to move to
this architecture.
How many pairs of UTP cable does NCA needs for best performance? Does it
use two or three pairs?
Which is the wide range recommended, 10 base T or 100 base T ?
thanks a lot for any comments,
Dina Dubon

Your "backbone" really needs to be 100MB. We are currently on 10.7NCA over
NT network. Our servers go into 100 Base T switch. The clients are
primarily 10base-T. Beef up the clients. They need everything you can give
'em. The minimum recommendation from Oracle is just that -- the *minimum*.
It'll run, but you won't want to be using it. :-( I have a second
facility which accesses via T1. This is OK, unless they are doing extract
from oracle. Oracle is very sensitive to network latency.
Good luck ---- Hope this helps a bit.

If using seperate database and Apps server, ensure you have the
fastest available network connection between them as network traffioc
is heavy.
Use 100Mbs lan connections I believe all Unix servers (& NT servers)
have this capability.

We used 100Mb in the data centre. We ran multiple VPNs behind our
servers for SQL*Net between forms and database servers and backup
traffic from all servers to the Net Backup server. These were separate
from the public traffic. Our users are all over Europe and find that an
allowance of 5kb per concurrent user over the WAN is plenty of capacity.
This might vary depending on the level of activity. My impression is our
users have a fairly relaxed work ethic.

WAN - working through

Subject: Working through WAN
We have many network errors, working with ver. 11.0.2 through the WAN (Wide
area network), one DB on one local server, form server & web server.
Is anybody working with the same configuration and can help us or even tell
us that he has the same problems ?
