Re: Correlating *SAVF "records" to FTP job I/O count

[Patrick Townsend <townsend@xxxxxxxxxxxxxx>]

Dan,

I believe the transfer record size of an FTP transfer will be controlled
by the Maximum Frame Size of the line description. Save file record
lengths are 528, but I believe FTP should send multiple records with
each transfer. You can see what the AS/400 is doing by putting a
communications trace on the line (STRCMNTRC). End the trace with
ENDCMNTRC and then print it with PRTCMNTRC. There is a header for each
TCP/IP frame, but you will get an idea of the size this way.
