Hi, friends
I work in a medium company and I was requested to configure a HIS 2004
server to access a remote AS/400 server, i don't have previous experiences
about this, but i'm trying to research, so i need a procedure to help
configuring DLS over a TCP/IP WAN Link from a HIS 2004 server to an AS/400
through another HIS 2004 using TCP/IP.

If it posible, i would like help about some basic concepts like LU, LUA,
SAP, TN3270, TN..., if you could send some .doc or .pdf file i will be very
thankful

Thanks a lot for your help.

Ok, here is the "simple" way of doing it.

On your central server (the one that has a connection to the AS/400), create
a link service and click the "distribute" option. When you do this, the link
is "shared" as <servername>\<linkservce> (linkservice would be similar to
snadlc1, snadlc2, etc. Nothing else you need to do on the central server. Do
not attempt to use this link locally either.

Then, on your "remote" server, create a distributed link service. For the
Link Type, you normally use the type of link service the card in the
"central" server has (ethernet, token-ring,etc). For the Primary Remote Link
Service put in the \\<servername\<linkservice> name configured above. Click
OK. Next, create a connection using the PU and give it the MAC address of
your AS/400, etc. Just as if you were configuring the link on the central
server.

Once you do the above, start the link, and it should go active. It will
communicate via TCP to the central server, which then passes it to the
AS/400.

Felipex,

Do you know why you've been asked to install another server? It sounds from
your description like there might be an existing HIS Server local to the
AS/400. If that's the case, then what's the reason for another HIS Server?

"Remote" users can just connect via the HIS server that's already there over
tcp-ip.

Your best bet for an SNA fundamentals document is going to be a google search
- I'm sure there will be something on the IBM website for instance. But google
will find it for you easier than searching by hand.

I was asked to install that another server HiS 2004 because of we have the
next escenary:

(HIS 2004) <Router> <MPLS Link> <Router> (HIS 2004 <DLC> AS/400)

Where:
The firts His server is in one country and the second HIS server is in
another country in the same LAN that the AS/400 server.

My question would be: if the comunication between the firts HIS server and
the second HIS server needs some especial configurationif a use DLS over the
HIS server?

Some people said me that could not be posible to connect the two HIS servers
due to we need to use the mac address to point to the second HIS server in
the AS/400 LAN, is that correct?

Over what kind of WAN links i can connect HIS servers with DLS to access an
AS/400 server?

Thanks for your response Charles,

another country in the same LAN that the AS/400 server.

I would like to know if the connection between the two HIS servers needs
some especial kind of WAN Link?, my question is because some people said me
that i need to point to the mac address of the HIS Server on the AS/400 LAN
and that wouldn't possible through an MPLS Link or over a routed network.

What requisites should the WAN link meets to allow the connection between
the two HIS servers?

Felipex - this IBM book, which you can download as PDF or view as HTML has a
reasonable coverage of mainframe SNA and TCP-IP stuff.

AS/400)

Where:
The firts His server is in one country and the second HIS server is in
another country in the same LAN that the AS/400 server.

This is what I assumed you had. As long as the link between the two LAN's that
HIS2004 is sitting on in both buildings is tcp-ip (which it should be with routers
and an MPLS link) then you don't *need* a new HIS2004 server on LAN-A, because all
those clients can connect to HIS 2004 over tcp-ip quite happily.

Quote:

Distributed Link Services talk over tcp-ip between HIS servers, so there's no
special network config needed.

No, you don't use a MAC address. It's done over tcp-ip. The only thing you use a
mac address for is for the comms between HIS and the AS/400 - if you're using the
DLC protocol, which it looks like you are from your diagram.

If your issue is that the HIS2004 server near the AS/400 is on an separate network
and can only see the AS400 and not the router (over tcp-ip), then the solution to
that is to put a 2nd NIC in the HIS2004 server. Configure the new nic for tcp-ip
only and patch it into the routed lan. Leave the other nic configured for dlc and
in the AS/400 LAN. This is a very common setup. Then your remote clients, or your
remote HIS server(s) can communicate with the HIS2004 server near the AS400 and get
access to the AS400 resources.

Quote:

AS/400 server?

Anything that supports tcp-ip. (Other protocols like netbeui, nwlink(netware) and
appletalk are all being deprecated)

If you do still want to use another HIS server and DLS to communicate between them,
then follow Charles's instructions.

Note that the main use for DLS was in the days when WAN links were very slow - the
reduction in wan traffic that DLS could give you versus individual clients
connecting over the WAN to the remote HIS server was important then. It is of far
less importance these days and so I rarely see it used in new installations.
