JCL to copy dynaicall named input file to mainframe file

MB · New User Joined: 25 Jun 2008 Posts: 20 Location: Hyderabad

I have a file with name TXMMDDYY in EBCDIC format. It is being sftp'd through a Java process to Unix Services system. Now I need to run a job after copying TXMMDDYY in EBCDIC format to mainframe file.

The problem is the name of the file in EBCDIC format is dynamic.i.e., it has date in the file name. So everytime I run the Job i need to modify the file in EBCDIC format. But the requirement is to automate the process of copying the file and then running job.

remove the date from the file name

We cannot remove the date from the file name, because it is a requirement of JAVA people to generate a EBCDIC file with date in the file name.

if You described the process a bit better somebody might come up with a solution
please describe the overall requirement for the date construct in the file name

do You need to carry it on also on the mvs side of data management ?

if it can be dropped, somebody enforced a useless requirement
let the JAVA people build the local name in any format they want
require that the file be ftp'ed in according to the mainframe requirements

I'll admit I don't know much about USS, but can't you use the LIST command in a shell, with the results piped to STDOUT which could point to an MVS dataset? Then, all you'd have to do is read the STDOUT dataset to get the dynamic filename and generate the proper code to perform the copy?

I don't think ls output can be piped straight to an MVS dataset. However, this code has been tested using batch TSO:

The file in EBCDIC format is sent by java people through sftp process. The file is sftp'ed from Java server to Unix Services System with the name TXMMDDYY.EBCDIC. MMDDYY stands for the date on which the file is sftp'ed.

My requirement is to get a file in EBCDIC format with dynamic file name to mainframe file through FTP process.

Mairaj: your requirements are not clear. Putting the file on Unix Systems Services puts the file on the mainframe. It is there, in EBCDIC -- at least as long as your FTP job used binary transfer.

The dynamic file name doesn't matter since you don't discuss using any batch JCL or other process that would require the file name. Unless you've got requirements you haven't listed, you have what you want.

Ok then how can i view the file in MVS system. WHen am trying to read the file name with TXMMDDYY.EBCDIC format, it is giving me No dataset found.

Data Set List Utility No data set names found
Option ===>
More: +
blank Display data set list P Print data set list
V Display VTOC information PV Print VTOC information

Enter one or both of the parameters below:
Dsname Level . . . TX*.EBCDIC
Volume serial . .

Which version of z/OS you running? I know on 1.8 and later you have access to option 3.17 of ISPF; I'm not sure if it came in with 1.7 or not. But you do not want 3.4 -- 3.17 lists Unix System Services files.

it is 1.2 version

You can use OGET command to pull the file from Unix System Services to an MVS file name, or you can use telnet to access the Unix System Services directly to look at the file, or you can try OEIS or OMVS to access the Unix System Services file systems. Using telnet will require talking to a systems programmer on your system to find out what port is assigned to the Unix System Services access; frequently 623 or 1023 are used but there's no requirement for one of them -- it could 63137 if the systems programmer felt like it.

thank you. Can you please let me know on option 3.17 of ISPF.
