As/400

[pauloconnor]

Hi all,

We have developed an Order scanning application which runs against a Progress DB residing on UNIX. We are using terminal emulation VT220.

We now have a client who has a DB2 database.

I know we can connect to this using the Progress/400 Dataserver but I am unsure as to how we can use our terminal emulation application against the AS/400 (my knowledge of AS/400 would fit on a beermat).

Is it possible to run progress apps. using terminal emulation against the AS/400?

Also, can calls to HLL programs be made from such an application.

Any help on this would be REALLY appreciated.

Many Thanks,
Paul O' Connor

Well, since noone smarter than me answered your query, I guess it's my turn,
although I did AS400 only loooong time ago, in v8 times...

We had a Linux server running a `schema-holder' database - that is
just a progress db with nothing but a identical schema like that in the DB2
database, all the data are in the DB2; the character clients were connecting
via terminal emulation to the Linux box and connecting the schema-holder
there. The schema-holder then connected to the DB2 database with the
data (maybe with some kind of autoconnect, or something, my memory is
fuzzy with this one...)

So from your POW, your users should be able to use some UNIX box with
4gl programs, connect there via terminal emulation.

One last word of warning: it's not clear from your mail if you're going to
run the same 4gl code, only against DB2 database, using DB2 dataserver.
If yes, you're going to have some serious problems, don't believe the docs
that dataserver is able to isolate you from all differences between native
progress db and DB2, it's NOT TRUE (sorry for shouting). You'll end
(as we did in v8 times) with hardly maintainable code full of conditional
compilations.
