RE: AS/400 Xe performance issues

Judith :

WINS and/or DNS locations are VERY important on Oneworld, because this
software is very
dependent on machine names; I've suffered from this on many installations.
It's not a good idea to access OneWorld servers from a thick client across a
WAN Link,
OneWorld is a very chatty software and needs lots of bandwidth.
I strongly recommend you to use Thin clients (Citrix and/or JAS) for WAN
Nevertheless, you may start trying to install WINS or DNS (primary and
secondary) on both
ends on the WAN link to avoid name resolution delays and restrict a little
bit your bandwidth
If you don't want to spend too much time configuring WINS or DNS servers,
try the old HOSTS
or LMHOSTS files. You may define there your TCP/IP address vs. machine
names tables,
specially for your Deployment, Enterprise, PDC, DNS, etc.

Asunto: AS/400 Xe performance issues


We have recently installed OneWorld software on a new AS/400 enterprise
server with substantial computing horsepower and minimal other resident
applications. As we begin to prototype, we have about 5 users on-line at any
time using the JDE Thick client on NT-based laptops or desktops. The NT
domain we are part of is a large Corporate domain with many computers in a
LAN/WAN scenario. At our location, we have a Windows NT Backup Domain
Controller (BDC) and backup DNS but the Primary Domain Controller (PDC) and
DNS are both remote at a location far away. The WAN connection between our
location and the central site is a 768KB Frame-relay link. This link
experiences occasional outages or slowdowns.

During our initial configuration and testing, we have generally had slow
client performance but have had several periods of VERY slow performance
when communicating between the OW client and the AS/400 enterprise server.
This manifests itself as slow program loads, slow interactions between
forms, etc. This doesn't make sense given the size of the enterprise server,
it's typical CPU usage at the time or the LAN traffic. Therefore, we assume
the problem to be network related and perhaps associated with our WAN
connections. Several of these extreme slow-downs have coincided with known
performance problems on the Frame-relay link to the Corporate site which
leads us to suspect that our OW installation is somehow relying on something
outside our local LAN, perhaps a service that it uses over the WAN.

So, here's the real question: What is the significance of WINS address
resolution, Windows Master Broswer resolution, DNS and access to PDCs to the
JDE OneWorld software? In our case, could we be experiencing slowness due to
the fact that these functions don't exist on our local LAN segment? Would we
experience better performance if the PDC or WINS machines were local? Is
there a manual or document or an expert at IBM, JDE or Microsoft that is
known to provide recommendations about the placement of these Windows NT
services in relation to JDE OW?

Please point us in the right direction for these resources if you know of
them. Thanks very much.
