Re: What exactly needs to be installed and started on the iSeries for Webfacing and HATS.

John,
"I don't understand what you're saying about HATS though, what needs to be
running on the production iSeries for HATS to function, something has to
do the 5250 stream translation on the fly?"

Nothing has to be running on the System i. The HATS application starts a 5250 session, reads the 5250 data directly and transforms it on the fly. That is why you can be running HATS on your local PC in a WAS instance with nothing installed on your System i.

For example, we sell a set of HATS transformations for a particular 5250 based product. When we demo the product, we directly connect to the customer's System i and show them what their data looks like in our HATS application. We had to install exactly nothing on their system in order to have HATS to work with their applications and data. That is the cool thing about HATS. It can have zero footprint on the System i if you deploy to a different server (Windows or Linux, for example).

Thank you Cheri,

This is the kind of basic info I was looking for.
So... if I understand you correctly, the only thing that needs to be running on the production iSeries for WebFacing is the WebFacing server/service?

I don't understand what you're saying about HATS though, what needs to be running on the production iSeries for HATS to function, something has to do the 5250 stream translation on the fly?

What about the combined WDHT product that is both WebFacing and HATS together, which is what I believe we will be wanting to use in the end because we have common system calls (like wrksplf) built into our application that can not be WebFaced.

I just want to get a good idea as a programmer what I need to tell the system admin folks as to what will need to be installed and running for a WebFaced/HATS application to run on each iSeries.

John.

Your networking and DNS entries all have to be setup and in place and I am
in no means an expert in all of that but if that is setup correctly the only thing you need to running on the iSeries for WebFacing or HATS is to have the WebFacing server/service started on the iSeries.

You can have a Windows server that is running the Apache HTTP server and you can purchase a license to run WAS on a windows machine. You can deploy your ear file to this Windows server and as long as your network is setup that the windows server can find your iSeries host and you may have to open a few ports your application should work. If you have a WebFaced application then you will need the WebFacing server piece started on the iSeries. For HATS
no special piece needed on the iSeries.

Here is a link to IBM WebFacing Troubleshooting that may give you some insight or what is needed on the iSeries

You will want to make sure that you have the latest PTFs on. As well as they are slowly changing and merging WebFacing and WDHT(HATS) and depending on what version of V5R3 etc will depend on whether these products use interactive cycles and whether you need a license for WebFacing etc. The beauty is that with WDSc you can develop and try this out before making a decision

Would someone please answer a couple questions for me about what HATS

and

Webfacing.

I am working on a project to Web enable a green screen application with
instances running on 100 different iSeries boxes. The application is

the

same on each box, the only difference is the data.

What exactly needs to be installed on each individual iSeries for
Webfacing and HATS to work on that box.

I understand that the application server doesn't have to be running on

the

iSeries itself, such as is the case when we are developing in WDSC and
using the provided WAS server running on the PC.
But... in the Webfacing project you specify a specific Host name.
Is there a way to have the project published to one Web
application server and have a "portal" or initial page allow the user to
select which "Host" iSeries to connect to or can a project only have one
"Host"? Or do you have to have an individual project for each iSeries
"Host"????

Thank you.
