Well there are some factors that can influence your design
choices. Obviously the customer has a specific (or set of
specific) legacy application(s) in mind, as well as OS
platform(s). If you could get some more details from the
customer regarding their situation it would be useful.
For example, if the legacy application only has a command
line interface, and no programming interface (API), and
the platform is VMS, then the ObjectBroker script server
functionality could be used to wrap the application. Or
on a UNIX server you could also use the script server, but
you may also be able to write a real OBB server and interface
to the legacy application using something as simple as popen(3).
Also search this and the other ObjectBroker notesfiles for
"script server", there are lots of topics relating to the
script server that can give you a feel for it.

| 1394.2 | it's always a different story | EMNTAL::STADELMANN | Sepp @ZUO 760-2609 | Thu Apr 17 1997 06:00 | 13 |
| Did this custumor consider FBE and buying a workshop.
Legacy Integration is almost a different issue. AS .-1 points out.
API, direct DB access out of Method, CMD Line issued from a Method,
Script Server for simple things, Screen Srapping if nothing else helps.
Also if the Legacy to wrap is on a IBM MVS IMS DB2 system, maybe one
has to deliver this using the the APPC Protocol API in order to setup a
trabsaction for the DB2 system, i.e. calling APPC in the method and
code something in RPG on the other side. -> Paolo Catholico migth help
you on such legacy integration @VBO .
Sepp,

Except that FBE has been sold off.

Thanks for the replies, folks. We are aware that every such integration
project is likely to have a lot of custom code. I suspect the customer
just wants an existence proof. I'm hoping the bale of white papers
I sent will satisfy his curiosity for awhile.
Re: .3. Yes, FBE has gone to Linkvest, but Linkvest is still a valued
partner. It may be that the right approach is to connect the customer
to a Cushing or Linkvest...
