Yes, there is a gzip for z/OS UNIX. You can download it from: http://www-03.ibm.com/servers/eserver/zseries/zos/unix/bpxa1ty1.html To the best of my knowledge, it is a straight port of the UNIX gzip and does not use the hardware compression functions of the zSeries processor. > we are thinking of NFS mount the z/os volume and do the gzip on the > z/linux and then Ftp'd the data. What? If you NFS mount the z/OS UNIX directory on z/Linux, you will still do a lot of IP traffic. Granted, this could be fairly fast if you are using Hipersockets between z/OS and z/Linux. If you do this, I would strongly suggest that you gzip with the source on the NFS mount and the result on a "native" filesystem under z/Linux. Then ftp from the z/Linux system to your UNIX system. gzip </nfs/subdir/input.file >/local/subdir/input.file.gz ===== In either case, remember that you must do a BINARY ftp of the gzip'ed data. And once on the UNIX system, you must gunzip it AND CONVERT IT FROM EBCDIC TO ASCII! (well, unless it truly is BINARY data. How you would convert that is difficult to say). The gzip'ing process does not convert the z/OS data from EBCDIC to ASCII. So you must remember to convert it on the UNIX system. I guess using "iconv". What I'd likely do, on the UNIX system, is: gunzip <input.file.gz | iconv -f IBM-1047 -t ISO8859-1 >output.file.in.ascii > > Thanks -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
