NCA Network considerations

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 ?
