Hello All,

Could you please let me know is there a way (command in cics) to find out the all CICS programs that uses a file in that environment and in what mode(Read/Update/Delete).

I have searched for a while but couldn't able to find the related topic.

Your answers are really apprciated..

Thanks Enrico for ur quick reply. So Is there any other way to find out the programs for a file?

Since a file name can be a constant in the EXEC CICS command, or an elementary variable in either COMMAREA or WORKING-STORAGE, or a group variable in either COMMAREA or WORKING-STORAGE -- and could be located in a copy book not in the program source, you really have two choices: (1) consult the application documentation while praying that it is complete and up to date, or (2) read the code (compiler output would be the only way to be completely sure of the file usage).

what about looking at the application documentation ?
usually such cross references are built when developing the specifications

but there might be products ( $$$$ ) which might cross reference almost everything

Hi Robert, Enrico,,

Unfortunately, application which im working is an old system and documentation were not up to date. Hence now feeling really tough to backtrack.

well, You will have a lot of reading and scribbling to do ,

unless You are skilled enough to write a REXX to parse the sources or better the compile listings to extract the required info

Hmm, Thanks for your valuable comments,

Not a better Rexx performer,

anyway will dig in some manuals, Lets see if some1 can help out..

Yes, when the application documentation is not up to date and complete, the task of identifying resources used by the application (files, programs, and so forth) can be a complex and time-consuming task. For every program in your application, you have to identify each CICS command accessing a file (remembering that those commands may be located in a copy book being brought in during program compile), identify the file being used in each command (and, again, the file defintion as well as the CICS command could be in a copy book), and then document this usage somewhere. Tools are available (Google impact analysis or code analysis to find some of them), but if your site does not already own such a tool it can be pretty expensive to acquire.

we have statistics about file usage <==> transaction (cics monitor collects this data). your shop may have similar data available. whether this data is also easily available on program-level i don´t know.
