Hi,

Detailed explanation of my requirement is as follows.

Over the couple of months we are NDM'ing the files across UNIX server from Mainframes using the below NDM card

SIGNON CASE=YES
SUBMIT PROC=UNIXSND9 SNODE=AB.UNIX.XYZPAPAB -
NEWNAME=NDM-CARD-NAME -
&HOLD=NO -
&FILEIN1=MAINFRAME-INPUT-FILE-NAME -
&FILEOUT1='/unix_feed99/UNIX-DIRECTORY-NAME.TXT' -
&FILEIN2=MAINFRAME-DUMMY-FILE -
&FILEOUT2='/unix_feed99/UNIX-DIRECTORY-NAME.OK' -
&CA7JOBI=NDM-CARD-NAME
SIGNOFF

We are supposed to send a mainframe file to ICARUS with size of 25GB, Ofcourse, we NDM'ed it successfully as part of testing, But NDM team suggests us to look for an alternate approach rather than sending a large file daily as it affects other batch process.

To increase efficiency and more, They have suggested that you try different compression levels and checkpointing before you go live, to achieve the fastest transfer of the data.

Can anyone suggest how to amend ( which parameters ) the NDM data card to fulfill the above requirement.

Can we compress the file on mainframe (before sent) and uncompress on UNIX (after sent)?

No, not until you show us the contents of the process (UNIXSND9).

Yes, although you'll have to weigh the benefits of using valuable CPU cycles to do so. You could use a commercial-grade compression tool like PKZIP. Since the endpoint is Unix, you might look at using some of the standard Unix compression methods (like gzip) to meet your goals.
