Hi,

Could you please sugget some FTP options to improve FTP effeciency like speed & data integrity, which you have come across over the years.
I was able to find some like TYPE E (EBCDIC transfer) & MODE S (Streaming) which improves speed to some extent (I think). Could you please suggest some more.

Thanks & Regards,

Hello,

There should be no issue with data integrity - possibly i misunderstand what this refers to. . .

The speed is closely tied to the size of the "pipe" the data is being sent thru. Suggest you talk with your network people to learn if anything faster is available (if you have some transfers that take too long). Keep in mind that both ends of the "conversation" must be able to handle the higher speed.

D,

Thanks for ur time responding, by data integrity i was meaning the restart capability of a failed transmission and possible production issues which maybe associated with various FTP options available.

For example, while transferring some type of MF data we cannot use ASCII mode of transfer since it may result in data loss.

I've never heard of data loss just because you are using ASCII mode. If your data file being transferred has non-display data in it, defined as binary (COMP), floating point (COMP-1, COMP-2) or packed decimal (COMP-3) data (also COMP-4 and COMP-5 for COBOL people), you cannot transfer the file in ASCII since the data will be translated from EBCDIC to ASCII. No data will be lost, but data values will be changed since non-display values are converted using the translation table.

Oh ok, I was with an impression that non readable stuff are lost during the transmission. My terminology was a bit off.

Thanks, "Donald Knuth" icon_biggrin.gif
