RE: Communications Questions

[Steve Morrison <smorrison@xxxxxxxxxxxxx>]

Mike,

I'll start off with a couple of questions.

1. How sensitive is this information? (confidentiality)
2. How important is it that each record gets to system B?
3. Must the records arrive in order?
4. How reliable is your communications link between the machines? (always
active, drops on rare occasions, drops on a regular basis?)
5. What happens if a record(s) get sent twice?

My first suggestion would be to use remote journaling. FTP is possible, but
I would recommend a third party FTP package. The last time I used the AS/400
FTP, it was a blind batch process. I know others have written program that
use API's to monitor FTP now, but we didn't have that available.

Subject: Communications Questions

All,

I am looking for some ideas.  Let me explain the problem.  We have an
iSeries located in a building, lets call this iSeries A.  We have another
iSeries located in the main office.  Lets call this iSeries B.  iSeries A is
used to process information about the sales of cars.  iSeries B has web
services running on the machine and processes a subset of a file from
iSeries A.  We have a trigger for the file on iSeries A that will process
only the records that are needed for this process.  The trigger program
saves the information we need to a hold file.  What we need to do is
transfer the information in the hold file to iSeries B either in real time
or near real time.  The file must be transferred over the internet, so DDM
is out of the question (there are too many issues with error recovery when
the communications go down in DDM).  We were kicking around the idea to FTP
the file, but this must be all automated.

Any ideas on a solution?

Thanks...
