SNA Server to SNA Server Connectivity

[landrew5]

Hi everyone,

I have an issue in regards to connectivity between two SNA Servers. We currently have an SNA Server in house that services all the internal employees and has a connection to a mainframe offsite. We will soon have a vendor connect to that SNA Server using an SNA Server on their side for an e-commerce application we are selling.

In between the vendor's SNA Server and our SNA Server are a few routers and one firewall. The vendor has stated that they will not do a Distributed Link Service and that they prefer to run DLSw on the routers. My question is then does this require a downstream connection to the vendor's SNA server with LU's that have been created in a connection to the mainframe??? Do they also need some method of authenticating to our SNA Server??

Any insight as well into the configuration of DLSw would be greatly appreciated. Thanks everyone.

We have a similar issue. Any dlsw experts out there??

Why push DLSW. Why not create a downstream link on ethernet and bind DLC to that card. Another option is to allow the link service on the HOST sna server to be distributed (under the link service definition) and then define a distributed link service on the remote SNA server. The remote sna server should communicate with the host sna server via IP and the Host SNA server will continue to communicate via DLC to the Host Mainframe. I have not tried this over a router but have tried it across a network and it work without having to run DLC on the remote SNA server.

Let me know how it goes and good luck.

In our case, at least, dlsw is the only option the customer will consider. It would help me to know if, when using dlsw, do you use the 802.2 link service that comes with Host Integration Server, or do you use a custom link service? If it is custom, what is the source?

I use the one that comes with HIS. You have to load the HIS SP1 first in order to add the dlc link service.

I would go to the Microsoft Host Integration web page then go to the community newsgroup and post this question. You should get an answer from one of the Microsoft HIS support persons.
