Terry,
I worked on what I think is a similar process. We are running SAP and need to
be able to ftp files on and off of our unix SAP servers. Someone in the past
wrote an SAP ABAP program that does all of the set up then calls a unix shell
script to perform the ftp. If the ftp command truely failed to connect we had
no problem getting back a failed error message to the SAP program. But where we
ran into some problems was when the transfer command would start but get
interrupted for some unknown reason and never fully complete the transfer. This
was noticed by accident one day when someone was checking a report run off of
one of the data transfers and there were only a few hundred records in the table
to be processed instead of a few hundred thousand.
I was then asked to come up with a solution that would look for an unexpected
termination of the ftp connection. After lots of searching and getting one of
our local unix gurus involved (I have worked directly on a unix platform), we
implemented the following. It is not the best but it does seem to be working.
We added a step to the ftp script. This step is a status command that is
executed directly after the get or put command. This returns information about
the ftp connection itself. It also returns a message if it is no longer
connected. This output was passed back to the SAP program and parsed. If I had
a message indicating that the remote host was still connected, I assumed that
the get or put executed completely. If on the other hand I received the message
indicating that the remote system was no longer connected I generated an error
message from the program so that the user could check the data.

RE:
I think I've seen an answer to this, but I never needed it before. If
anyone can help, I would greatly appreciate it.
We are trying to ftp files from one server to another. (Archive logs
for Oracle). We want to be able to capture the status when the ftp
fails, so that we can notify the DBAs to check the process out. This is
all being done within a shell script that compress the log file first,
then calls another script to do the actual ftp. But when the child
script executes, it returns a successful status to the parent script. I
don't know any way to tell the script that is doing the ftp to send the
message, because any non-ftp command within that script fails. (Of
course, that could just be because I don't know how to do what I want to
do).
If anybody has invented this wheel before, or has any tips on where to
look for more info on how to do what I need to do, please let me know.
TIA,
Terry
