Hi,

Can you please assist in how to convert mainframe JCL in MVS into the Unix scripts. Please share any tools or sample procedures that I can use in my system.

What have you done? What problems did you encounter? Why would we do your work for you? Maybe you can ask your employer to outsource this kind of work to countries where people spending a day reading a manual are still cheaper than using their own staff?

Hello,

Once upon a time, i was the project lead for converting/migrating an IBM mainframe data center to UNIX. We found that many of the batch processes were quite similar. We made a few "model" scripts and cloned them as needed for the various "batch" processes.

What you really need is one (or more) analyst(s) who are fluent in both JCL and UNIX scripting. Keep in mind that while the functionality of a shell script can be the same as the original mainframe JCL, the mechanics are quite different. Also, many of the "things" used on the mainframe are not part of UNIX. The more the mainframe has custom utilities, the less likely there will be an available UNIX function - so these will have to be replaced or re-implemented on UNIX.

We decided that any tool would be as much or more work than simply converting the processes one-by-one once we had the model scripts working.
