Re: FTP problem

     Kevin,
     
     Is it possible to rename the transaction file then create an empty 
     file with the original name? Then you can FTP and process the 
     renamed file without wory of dups or lost transactions. The only 
     real problem I can see is if a record is added between the rename 
     and the creation of the new trans file. Rename and copy (from a 
     blank version of your trans file) is pretty fast, but unless you 
     can hold new transactions until the new file is in place, you'll 
     eventually have problems.

I have a text file on a Novell Server which is constantly being added to. I 
have an AS400 program queued to run every 5 minutes which will FTP from the 
AS400 and GET this file. I then need to clear the server file so that the 
next time I do a GET I'm only GETting new records. As there is no ftp 
command for clearing a file how can achieve this? I've thought of DELeting 
the file and then PUTting an empty version of it back on, but how do ensure 
that I don't delete any records added to it since the GET? I cannot risk 
missing out on any records that would otherwise be added to the server file 
while I am manipulating it. At the moment my only solution is to continually 
GET all the records and then decide on the AS400 whether or not they have 
already been processed, then clear the server file on a daily basis, after 
production is finished. The server file will have maximum 2000 records by 
the end of the day, so reprocessing the same data over and over will not 
impact the AS400 too much, but it's not an ideal solution. Does anybody know 
the 'ideal' solution?
     
TIA,
