Hi,

During a conversion project we came with the list of unreferenced programs in the application. We used relativity workbench (a legacy application modernization tool) to come up with this list. We want to double check the correctness of this list before removing the programs from the application. Can anyone suggest a foolproof method to confirm that the programs are really unreferenced and it is safe to remove them?

Regards,
Arun

Hi,

Since these are unreferenced (not invoked anywhere)it is not possible to test them. I was asking for a easy way to confirm the list we have. Also, list comes to around 400 programs.

Thanks,
Arun

Get a program that is designed to do this. SoftAudit, for example, monitors program load activity (load modules) and tells you what was actually used. Of course, even this will not catch the case where a program would only get invoked in unusual circumstances such as once a year at year-end, or during a particular type if crisis such as I/O errors, system intrusion, etc.

Not knowing what your modernization tool uses for input?

JCL/Proc libraries
pgm source list analysis which will resolve any and all dynamic CALLs (e.g. pgm name read from a file, level 88 values,)
JES archive
program documentation???
talking with customer support personnel

can't say. But if you have gone thru all the above, delete them. Suggest that you have a very well designed retrieval system when you do remove them and encounter suprises in the future.

SMF "step end" records can show programs that were directly invoked via jcl PGM=XXXXX, but not called subroutines or online programs (CICS, etc.).

I second Dick's suggestion to be ready to replace them quickly.

Hi,

As semigeezer said we will go with the soft audit report even though it might not be foolproof as there seems to be no other go.

Thanks a lot guys,

Arun
