Distribued Systems Node Executive Transmission Server

      A program is disclosed that provides a method for
communication between Netview Distribution Manager operating in a MVS
or VM host system, and VM/DSNX (distributed systems node executive)
operation in a distributed VM system.

      Netview Distribution Manager (NDM) communicates with remote
nodes through VTAM using an LUO protocol, whereas VM/DSNX
communicates with remote nodes via spool files.  The Distributed
Systems Node Executive Transmission Server (DTS) is the vehicle by
which NDM and VM/DSNX communicate.

      DTS serves as both a protocol converter between NDM and
VM/DSNX's DSNXSERV virtual machine, as well as a bridge between VTAM
and CMS, since CMS cannot directly communicate with VTAM.  NDM sends
its commands and data to the remote VM system using an LUO protocol
over a VTAM communication link.  DTS receives the NDM commands and
data via VTAM RECEIVES, maps the command to a VM/DSNX command and
puts the command, file characteristics and data into a spool file.
The spool file is then sent to the DSNXSERV virtual machine.  VM/DSNX
processes the command and data, puts the response in a spool file and
sends it back to DTS.  The server then decodes the spool file and
sends back the appropriate response to NDM (Fig. 1).  The
relationship of the DTS to other major system elements is shown in
Fig. 2.  DTS is implemented as an RSCS session driver and, as such,
is actually part of the RSCS virt...
