Program Comparison

Use the Program Comparison option (5.3) to compare two source programs or two load modules. CA Auditor automatically selects the correct display. You must have read access authority to the libraries that contain the programs you want to compare.

CA Auditor cannot perform comparison operations against load modules which are already loaded into the TSO address space. Examples of such modules include CA Auditor itself, TSO modules, and ISPF/PDF modules.

1

Determine the names of various exit modules and the libraries where they reside using the z/OS Exits display (3.3).

 

 

 

2

Obtain archival copies of these load modules, and then use the Program Comparison display (5.3) to pinpoint differences.

 

 

 

3

Search SMF records for any evidence of an update to the library of any changed modules using the File History Search (6.5).

If available, use information from the Program Freezer (5.5) to narrow the interval to search for the jobs and programs that updated the libraries you found in Step 2.
