We had a similar requirement to transfer vast amounts of data across a small network link from one site to another. We used PKZip from PKWare to achieve it. There is a cost to the software I think,...

Consider getting one of the mainframe coders to write a small bit of ANSI COBOL. Use that to transform the packed data.

Here is a discussion of the COBOL needed.
Packed Decimal...

If you have packed data on the server, your best bet will be to unpack the data on the server to a straight text format either in ASCII (if you can which won't require any further conversion after...

dd has built in ASCII - EBCDIC conversion.

dd if=oldfile of=newfile conv=ascii gives you a file converted from EBCDIC to ASCII. The only caveat is: do you have packed decimal data (raw "binary"...

A "mainframe" might supply differently coded files, e.g. EBCDIC. Try to transfer the file in binary mode and then convert it using e.g. iconv or recode.

OK. So your data is NOT EBCDIC; it is some kind of "abinition" or "abinitio graph" (whatever they are) record format. Presumably the string fields were correctly converted by the dd command, but...

And what happens when you try the other code I suggested:
dd if=so_tran05.dat_bkp conv=ascii

Is this actually EBCDIC? Or is it something like packed decimal?

EBCDIC is a codeset; not a format.
Two common utilities to convert from EBCDIC to ASCII or UTF-8 are
iconv -f fromcode -t tocode EBCDIC_input_file
(you can use iconv -l to get a list of fromcode...

You could write a script that will run the other SB, SA, SC, and SD guaranteeing that SA completes before SC and SD start, allowing SB, SC, and SD to run in parallel, and guaranteeing that only one...

You are trying to set up something that allows process synchronization. This is usually achieved using some kind of IPC mechanism (Inter-process communication). You can use a lockfile.

Let's have...
