[comp.protocols.ibm] Interactive connection from an IBM PC to an IBM 3090 running CICS/VTAM

corr@lehi3b15.csee.Lehigh.EDU (Chris Orr) (07/24/90)

Hello all!  I am trying to define an environment which will allow our IBM
3090 machine to talk to a number of other hosts.  Among these other hosts
are S/38, AS400, HP 925, DEC VAX 8600, etc.

The thought is to use a PC as a go-between.  This will allow us to develop
a connection from the IBM 3090 to the PC (possibly using an LU 6.2
connection) that is standard for all hosts that want to talk to us.  Then
all that is needed is to develop software that runs on that same PC to
connect to the other host.  This obviously would be host dependant.  We
would like to have the other host's application programmers code this
connection (see diagram's TRAN 3 and TRAN 4).

So, the question is what is the environment/hardware/software that should
be used on this PC.

It has been suggested by IBM to use OS/2 and CICS for OS/2.  Is this the best
solution?  What other possible architectures are available ????

We are currently implementing a scheme similar to the one you propose.  We
have a 3090-300E that is being gatewayed via an IBM 8232 industrial PC.  The
industrial PC is really an AT bus machine modified such that it speaks SNA
on the channel side, and Ethernet via an Ungerman-Bass card on the other
side.  Hanging off of the Ethernet are various VAX, HP and Sun machines.
Serveral applications are currently being developed using LU6.2 to one of
the DEC machines running DECnet.  In installation of FAL-FTP from IBM is
currently also underway, to allow greater access for our 3270 users to general
network services.  Ask your SE about the IBM 8232.
