Please find the requirement below:

1. To identify programs getting executed in each step and corresponding input and outputs of the same step.

Given is lib which has list of procs.

I have to identify
1. Program getting executed in each step
2. inputs and outputs of each step.

Since number of procs in the lib is large doing it one at a time will take time. Can it be done using icetool or isrsupc utility.

You might get away with getting the program names
also with the dataset names ( apart parameter substitution )

but, You will never be able to find out the correct usage for all of them

... You might infer that DISP=(NEW,...) will be output datasets,
but nothing can be said about disp=(OLD,...) disp=(SHR,...)

There might also be dynamically allocated files that are not coded in the JCL at all!

We have done reports from SMF type 14(input) and 15(output) records to document programs after they have executed. You could look into that. Otherwise a careful analysis of each program (and called sub programs?) will need to be done.

I would support this method as being the most accurate.

Hello,

Do keep in mind that if you use smf data (which i agree is the best source of dataset usage info), you need to pull smf data for the appropriate time-frames.

For example if you pull 10 days of smf info (which is probably a lot of data) from the 15th to the 24th of a month, you would not have the info for all of the month-end jobs. Likewise, there are the "on demand" jobs as well as jobs that are scheduled quarterly or some other long interval that may need to be considered.

Depending on your Batch JCL type the analaysis can vary.
How about Database input and output?
How about message in and out from MQ series?

Do the mainframe discovery tools (BMC or Tivoli) perform this type of analysis when running a discovery?
