SNA/DS is unrelated to DDM Files; that reply seems to muddle the two
distinct features.? DDM can not copy /objects/ only data; e.g. data of
database source-members and data-members can be copied with the Copy
File (CPYF), whereas a "display file" can not be transported via DDM for
lack of an object-copy vs data-copy utility. The CRTFILE(*YES) of the
CPYF could be argued as offering support for an effective /copy/ of a
database file object, but very primitive, and unlikely to effect a
desirable outcome as compared with saves, minimally, per the lack of
capability to /copy/ logical file definitions; i.e. as a data-copy
feature, the utility would create a like-definition physical file into
which the data would be copied, instead of creating the like-definition
logical file at the target. The SNA Distribution Services can be used,
as could FTP, to transport objects [and data] that was previously saved
to a save file; however in my experience, abutting a storage threshold
is more cumbersome to deal with for SNA/DS than for FTP, because the
SNA/DS effectively requires two copies of the data at both the source
[sending] and target [receiving]. Copying save-file records over DDM is
possible, but the OS-provided CPYF utility offers no support; i.e. a
program would need to move the data, if DDM were utilized. Given the OP
indicates that a NFS setup is already available, does not that imply
that the two systems can be considered to be "on the same network" via
TCP/IP.? FWiW, the DDM has long been available directly over TCP/IP.
However, SNA over TCP/IP is available only via either of the AnyNet or
the Enterprise Extenders. The ObjectConnect feature referred-to in my
prior reply, requires a SNA configuration.
