Host on Demand
Is a mean to distribute applications on the web, 5250 applet is a ready made one, strong secuity. Needs its own server application. Each user requires a license.
iSeries access for Web
Included in Client access starting from V5R1 has almost the same user functions of CA, includind 5250 emulation that's a very good one, from some perspective (e.g. macro register/play) is better than PCom tn5250.
It's based on Websphere application server this implies:
- no needs to install anything on the workstation (but the browser, e.g. MS ie)., and uses the same host server as CA, so any security deployed for CA keeps on going.
- J2EE based technology, iSeries access for Web is supplied by an EAR file as any other J2EE application. Integrating it's web services is often only matter to put an URL some else where.
My opinion is that requires an extesive configuration to limit/customize user funtions, even if is ready to use with full feature users, on the other hand all users customizations are stored in a single XML file that can be edited by the web or on the server side too.
Printing emulation is not available, but the user can download spooled files, browsing output queues or owned spooled files cross queue, in different formats (pdf format too). Not sure but I think that PDFing through iSeries access for Web could not require the Infoprint Server License (nor product-key as well).
File transfer is available via a wonderfull SQL-Wizard, requested files can be viewed, downloaded or stored in an as400 folder (in differnt formats) by the user.
IFS is available in a fashion ftp-site-like for upload and download.
Requires a CA license for each concurrent user, any function he/she will use.
Performance are very good, you'll notice a little delay at login time only. Obviously performances need a minimum of power on the server, I'm using a 270-2432 (partitioned 30/80) fully satisfied.
Starting from V5R2 5250 activity via iSeries access for Web do not require interactive feature.
A very good work, amazing. I personally suggest this one.
Its a product that gives basically SNA/TCPIP 5250 and 3270 emulation + a communication layer with its own connection configuration. Each user requires a license
Hope this helps.

Host Access Transformation Server (former Host on demand?):
Access for Web (german):
Websphere Application server:
Websphere development studio:
Web facing (german):
The mayor differences:
- transforms 5250 screens on thy fly (simplest way, if you want to use
an application where you have no sources)
- transforms your DDS sources into stored web screens (few work, few
- you create a new html interface using java (redesign in a complete
development world, also program logic in java possible, powerful but
- licensed per user (for extranet, tele workers) or for unnumbered
- opens interactive sessions or calls batch programs on the iSeries
(an iSeries costs with interactive power 4 times more!).
Depending on the software you chose and the price you are willing to pay you
will see varying levels of support from full -- looka-a-laike -- products
to basic tn5250 access.
If you think that IBM is lacking in documentation, you will be very
dissapointed by most of the offerings on the market.
Has anyone out there done a comparison among the heavy hitters for PC 5250
emulation on Windows 95/NT platforms? I'm especially curious about magazine
articles and such that would illustrate the pros and cons of the various
packages out there. Thanks!
