Re: Death of SNA?

After reading the various posts on this discussion thread, I feel that 
some clarification on the recent V5R3 planning statement regarding SNA 
communications may be in order. 

There are no plans to discontinue the support of the numerous APPC based 
applications shipped on i5/OS including DDM, Display Station Passthru, and 
the various SNADs applications ( SNDNETF, SNDNETMSG, SNDNETSPLF, SNDDST). 
These IBM supplied APPC applications as well as any user supplied APPC 
applications will continue to be supported.  The message being conveyed by 
the planning statement is that most SNA applications will continue to be 
supported, but the underlying transport mechanism for supporting these 
applications will be IP based.

With Enterprise Extender support, which will be supported in a future 
release, the APPC applications will be able to run over IP.  Enterprise 
Extender is a technology that has been widely accepted in the industry for 
addressing the problem of allowing SNA traffic to flow over an IP based 
networking infrastructure.  Enterprise Extender will have significant 
advantages over the AnyNet support provided on i5/OS.  It will be easier 
to configure than AnyNet, provide better performance than AnyNet, and it 
will also support dependent LU traffic (3270 emulation, RJE, DHCF, NRF, 
SNUF) up to the mainframes when used in conjunction with Dependent LU 
Requester (DLUR) support. 

The following article published last week by Timothy Prickett Morgan 
provides some additional information on this topic.

Re: Death of SNA?






Good question.

There are multiple parts of SNDDST.  There's the use of it to perform the 
like function of SNDNETMSG.  Then there's the use of it to send email out.

Here, we already use a "command exit program" to convert SNDDST into Dave 
Leland's SNDEMAIL.  If I truly knew if that was dropping, I'd modify the 
program to let the programming manager know of yet another program that 
has SNDDST buried in it that needs to be modified.

Where does that leave SNDDST?
