7057.0. "Peer Server and 3270 data stream programming" by NQOS01::16.72.96.90::Cindy () Thu Apr 03 1997 16:49

What access routine do I use to provide 3270 data stream programming 
capabilites using the SNA Peer Server?  THe SNA 3270 Application Services 
specifically requires the Domain gateway and I'm very confused.  I'd like to 
use a "current" product ... the Peer Server... and provide this capability but 
I don't see a 3270 API equivalent listed in the Peer Server SPD.  Is it the 
DEc SNA HLLAPI access routine?

I'm so confused and I know it can't be this difficult...

Thanks

Cindy

7057.1Domain Gateway is a current productEDSCLU::GARRODIBM Interconnect EngineeringThu Apr 03 1997 17:0510
    The Domain Gateway is a CURRENT product. Its just as current as the
    peer server.
    
    As you've discovered the 3270 Applications Programming interface
    requires a Domain Gateway.
    
    I presume it is the PLU end of 3270 that you want to do not the SLU
    end?

7057.2What's the difference?NQOS01::16.72.96.114::CindyFri Apr 04 1997 09:3016
Dave -

When I called 1-800-digital, they told me that the Domain Gateway is NOT a 
current product - in fact told me that it wasn't even still available.  That's 
obviously not the case, but erroneous information is being dispersed.

What is the difference between the Domain Gateway and the Peer Server?  Why 
would I need one over the other.  It must have something to do with PLU and 
SLU?  What the customer explained to me is that they need to support LU2 
communications from Digital to IBM.  I think I need to ask them some further 
questions to decide on whether they need the Peer Server or Domain Gateway.  
Please help with the questions that I need to ask.

THanks

7057.3Are you OK now.DELNI::BARBER_MINGOLet me DANCE for youMon Jun 02 1997 10:4623
    Hi,
    	I'm not sure you ever indicated what operating systems are
    
    involved.
    
    On VMS systems, there are 2 forms of 3270 data stream.  There
    is the regular 3270DS where you code data stream INSTEAD of using
    a terminal emulator in to the mainframe.  There is also Reverse
    3270 (It requires a mainframe) that allows IBM mainframe users
    to log into your VMS system through the Domain gateway.
    
    On Digital Unix systems there is Reverse 3270 data stream (requiring
    a Domain gateway) and HLLAPI with TPS which allows you to
    write programs to run on TOP of your terminal emulation sessions
    through all of our gateways.
    
    You may not be able to get CT's, the original Domain gateways, from 
    Dec any more.  It depends on if we ran out of the hardware.  I thought, 
    however, you could still get ST's.  They also run Domain software.
    
    I hope that makes your options a little clearer.
