Pinned topic (1) Dead code metrics + (2) List of programs calling a program

‏2012-10-29T16:25:05Z |
Hi,
Requesting your suggestions on the below queries.

1. Reg: Dead Code analysis:
We are looking for RAA related metrics called “Dead Code” – this is at the program level(That is, dead code needs to be viewed at each program level; while we have a huge number of programs to be analyzed for dead code.
Is there any Custom query which can generate this metric (program name, number # of dead code LOC, dead code stmt numbers \ line) for Cobol programs on application level. Or is there any DMH table source for this?
2. List of programs calling a given program:
There is a diagram which shows the Fan-Out (no. of sub-programs) for any Cobol program.
We need to know if there is a way we can get the Fan-in (List of all programs that call this program).
Is this present in any tables DMH table?

    1) In the current release of RAA (v6.0.0.10) the 'dead code' (or more properly stated *unreachable code*) attribute for COBOL statements is not persisted in the data base. The 'dead code' detection is on-demand - a program-at-a-time, therefore the custom query your are after can not be written. The next fix pack (v6.0.0.11 - due out within the next two weeks) will persist the Code Review for COBOL rule results (including unreachable code) in the DMH_NUM_PROPERTY table. At that point custom queries may be written to access these metrics.

    2) The following SQL will give you all the programs that call a given program, assuming you replace ? with the comp_unit_id of the called program. It is the same query used on the Program detail page's Control transfer tab when the calling programs radio button is selected.

    
    SELECT cu.comp_unit_id , cu.comp_unit_name FROM $(SCHEMA).dmh_compile_unit cu , (SELECT DISTINCT cu.comp_unit_id FROM $(SCHEMA).dmh_run_unit_cntnt ruc , $(SCHEMA).dmh_compile_unit cu WHERE ruc.target_cu_id = ? AND ruc.caller_cu_id = cu.comp_unit_id) cu1 WHERE cu.comp_unit_id = cu1.comp_unit_id ORDER BY cu.comp_unit_name
