I had a need to do some of this stuff, and as others have mentioned used a
program to monitor a message queue. The method I used to acoomplish this
was a wrapper program/command on one system that did a save and sent the
SAVF to a specific user profile on the target SYstem. That user profile had
a break handling program running on the target system.

When the message that a savf has arrived is recieved by the break handling
program, it receives it, and then restores it. I use a naming convention of
the library it was recieved from to identify what library it came from and
has to be restored into.

However, there were some other things I thought about when getting this up
and running that may be mroe what you are looking for. For instance:

On the source system, the program that does the sndnetf could also place an
entry on a remote data queue associated with your target system. This would
allow you (in theory) to monitor a data queue on the target system instead
of a message queue (much easier in my opinion).

It would also allow you to send other pertinent data "with" the savf, for
example a change control reference number (that was what I had intended to
use it for).

Another use for this would be to allow you to specify a different restore
library for the save file, or any other number of possibilities I am sure
you could think of.

When you recieve the SAVF another thing worth considering is using the API
that allows you to list the contents of the savf before restoring it to
allow you to create some "fall back" objects, or to see if there are any
objects you might want to perform some preprocessing for, or check for
pre-existing objects in the target restore library.

This would also allow you to do something neat like package an install
program inside the savf file, extract it (conditionally, if it exists) and
run it to install the other stuff contained in the savf.. or have I started
getting to carried away ?

Anyway, just a few thoughts on how to apporach your problem, hope it helps.

Cheers,
Evan Harris
