this true? What specific effects does this have on typical interactive
programs that handle data entry or inquiry?
It depends on what you mean by 'batch' jobs and what you mean by 'web
facing'. Any job that performs 5250 I/O consumes Interactive CPW
regardless of whether it is a batch or interactive job unless something
has been done to the job to change that. You can prove this by
acquiring a display device from a submitted job and see that it uses
If you mean the IBM Webfacing product then yes, your terminal sessions
consume Batch CPW **IF** you are on the 800 series hardware or later.
On earlier hardware they consume Interactive CPW. The only other
non-intrusive web-enabling product that allows terminal sessions to
consume Batch CPW is aXes (US distributor is Linoma Software at
http://www.linomasoftware.com) from Arterial Software.
The intent of both these products is to allow you to run existing 5250
applications on Standard model (i.e., zero interactive capacity)
If you buy a zero interactive system you cannot run a normal 5250
workload without either using Webfacing, aXes, or one of the intrusive
converters such as those from Seagull, or Pluta Brothers, etc.
What about heavy transactional apps like Warehouse
Since most of these connect via standard Telnet they require
Interactive CPW to support the workload.
If I ran an old fashioned 5250 program and did not send it through the
"converter", would the job crawl slower than a turtle on valium? What
performance in general? Are HTML pages through web browser portals less
stable than the good old dumb terminal or is there no real difference?
Even on a zero interactive system there is enough Interactive CPW to
run a very tiny amount of 5250 workload. This is intended for system
administration and but one very light user is not likely to affect the
Again, it depends on what you mean by stability but in general web
applications are just as stable as 5250 applications (allowing for the
fact that you have probably moved to Windows and Internet Explorer
which are inherently unstable environments). Considering that most of
the application is still running at the host (OS/400 therefore very
stable) the only questionable part is the client.
What about a simple thing like your sign-on to qinter in the morning?
you visible running out of qinter? Are any jobs running out of qinter
they are web-faced?
Just because a job is running in QINTER does not mean it is an
interactive job. Issue SBMJOB CMD(DLYJOB 10) JOBQ(QINTER) to see what I
mean. What makes it an interactive job is that a user signed on using a
signon screen managed by the subsystem. Since non-intrusive
web-enablers such as IBM Webfacing and aXes use terminal devices the
user jobs still run in QINTER (or where ever the Workstation Entry
routes the device). Note: I have some recollection that IBM Webfacing
uses its own named devices and so may route to a different subsystem
but as I said previously the subsystem has no effect on the job type.
Subsystems are just a convenient way of grouping related types of work.
What about printkeys?
What about them? Their use depends on the application and the
web-enabling tool but be aware the browser-enabled applications can
make use of the browser's print facilities.
How do the "green screens" look appearance wise if you are only
them, not modifying them?
Again, that depends on the product you choose for web enabling. Some
are fairly ugly until you customise the screens. Others provide
reasonable effects straight out of the box. Since this is an aesthetic
factor you should look at examples on the various vendor's web sites
and trial the most promising ones to see for yourself.
Anything you can think of would be very helpful to us in making this
decision to convert to a web-sphere operation.
You do not have to convert to Websphere to web-enable your
applications. That is the direction IBM would like you to take but
Websphere is a nice idea badly implemented. It is simply too complex
and resource hungry to bother with for most OS/400 shops. aXes does not
require Websphere or Java and so runs with much less system overhead
than the alternatives, it also does not need to read or modify your
source code like the intrusive tools, nor does it require a conversion
effort or complex configuration.
**Disclaimer: I have an interest in aXes.
