Commitment control

Hi,

well, we have a shipment notification file, which is regularly polled for new 
shipments by a 
remote location. A shipment can consist of lots of records, so we need to make 
sure that 
remote gets all records and not only 99 because the last record hasn't been 
written yet.

A colleague came up with the idea to use commitment control here (we have never 
worked with 
it before):

             - start commit cycle
             - write xxx records
             - commit

He believes all xxx records will only get visible in the file when the commit 
is issued. Is this 
true?

I suggested to have a last-line flag and a logical only showing records with 
that flag active. 
Remote can poll the logical and when it finds the last record, then read from 
the physical file 
with the appropriate key.

Any other solutions for this problem?

Regards,

Oliver
