RE: FTP from IFS using zip file update

Dave,

How does the process determine the file number? Is it scanning a local directory or library between the FTP transfers? Could that directory or library have a lot of objects/files to sift through? Maybe it's nothing to do with the FTP itself but it's the scanning time for the next file number that's taking that 30-42 seconds?

The FTP Details

The i series is the starting point going to a windows server
System logs on and does a MGET and the job takes 4-8 minutes to complete

The second job starts at the iSeries and goes to the same windows server
The job is set up this way
FTP "IP ADDR"
then there is loop in the program to do this 132 times each time changing the ? to a file number
Log on
put file?.zip
put 1 to file?.txt
quit

Then the job end total time 90-100 minutes

Transfer rate is 1800+/- KB always less that on second

BUT in the FTP log on the iSeries between each log in, it can be 30-42 seconds

I hope that makes sense as to how I described it. We have checked all the data on fire walls and it checks out the way it should

A comtrace supplied by IBM instructions was taken and sent to IBM 7-10 days ago but nothing back from IBM yes

Thanks again Dave Willenborg

Dave,

FTP reads data and sends it. In pseudocode it might look like this:

1. Read a big string of bytes from file.
2. Send big string of bytes.
3. Was that the end of the file? If not, go back to step 1.

It doesn't know or care that your data is a .ZIP file. It simply reads
the bytes that makes up the file and sends them. The contents of the
file are irrelevant to the FTP process.

I suggest looking for network and/or system performance issues rather
than looking at the type of data in your files.

Has anyone used FTP to transfer .zip files from the IFS to another server. I am having a problem with the file transfer taking an extremely long time to transmit.

Any help would be appreciated.
