Hello Team,
Our job is abending with following error code in sysout. But when I looked into the IBM fault analyzer it is showing the job has abended because of S0C7. Sometime the Job ended okay with normal restart. But now the job is abending even after restart.
I have checked the data, everything is correct. There is no reason for S0C7.
The line number on which fault analyzer is showing S0C7 is an assignment statement where a PIC variable is getting assigned to bin fixed variable. The PIC variable has numeric value. S0C7 should not have occurred.
Could you guys help me identifying the error. This issue is occurring in production.
SYSOUT:
IBM0472S ONCODE=290 The INVALIDOP condition was raised.
Regards
Biswajit |

| How do you KNOW that the value is correct? Have you displayed it? Are you assigning into an array? |

If this were true, there'd be no S0C7.
Can you show the declaration of variables and the assignment statement(s). What value is being assigned?
Garry. |

Thank you Nic and Garry for the quick reply on the issue. It is very much appreciated.
PFB the variable declaration and assignment
PIC variable declaration:
2 kc_kondbah04 pic'(10)9' init(0),
Bin fixed declaration:
dcl inp_seq_num bin fixed(31) init(0);
Assignment and lines after that:
inp_seq_num = kcKond_h.kc_kondbah04;
if verify(work_seq_nummer,zero) = 0 &
seqi.seq_nummer ^= kcKond_h.kc_kondbah04
then do;
call u_fehler(16,'');
work_input_ok = 'N';
end;
Message from Fault analyzer:
The cause of the failure was program XXXXXX in module XXXXXX. The PL/I source
code that immediately preceded the failure was:
Source
File # Line #
------ ------
000000 000778 inp_seq_num = kcKond_h.kc_kondbah04;
Fault analyzer also mentioned the value of kcKond_h.kc_kondbah04 at the time of assignment and it is correct.
No one has any idea how to solve this problem. |

| What is the value of kc_kondbah04? You DO realize, I hope, that not all 10-digit values can be stored in a 32-bit word -- hence if the value cannot be stored in inp_seq_num, what happens? |

Max value a bin fixed(32) can hold is 2147483648. So the PIC declaration is Okay.
The program has been running for 1 year successfully with the same code. The problem is occurring since 20 days. There is no change in Job or program. The funny thing is sometimes the job executes successfully after restart in CTRL-M.
Some more information from fault analyzer.
Source
File # Line #
------ ------
000000 000460 INP_SEQ_NUM FIXED BIN(31,0) AUTO = X'00000000'
000000 000386 KC_KONDBAH04 PIC '(10)9' BASED = X'F0F0F0F0F0F0F3F5F5F9' |

Until you get a value of 4588313000 in the variable. Merely saying the code has run fine for a year (or 5 years or whatever) does NOT mean the code won't cause problems tomorrow -- it all depends upon what value is stored in KC_KONDBAH04, and unless that is a fixed value there is ALWAYS the potential for a problem with your assignment statement.

This implies the problem is something else entirely -- such as a wild branch or some other external action impacting the code. Such problems are notoriously difficult to diagnose and correct. If your site has a code analyzer, you need to turn it on for the program and take the performance hit until you collect enough data to figure out the true problem and resolve it. |

Robert,
IBM fault analyzer is pointing to the assignment statement . I have also mention the value of KC_KONDBAH04. The value of this field is X'F0F0F0F0F0F0F3F5F5F9' .
I did not say that If a program is running for long time it will not abend in future. This is a very strange problem. Now we are thinking about changing bin fixed variable to PIC. |

Sprinkle the code with "PUT DATA(whatever)" statements around the abend, or as anyone with a bit of sense would do, run the program through Debug Tool...
And ONCODE 290 (INVALIDOP) is not a S0C7!
| Quote: |
Status
INVALIDOP is enabled throughout the program, except within the scope of the NOINVALIDOP condition prefix.
Result
The result of the invalid operation is undefined.
Cause and syntax
The INVALIDOP computational condition is raised when any of the following are detected during the evaluation of IEEE floating-point expressions.
- Subtraction of two infinities
- Multiplication of infinity by 0
- Division of two infinities
- Division of zero by zero
- Invalid floating-point data

lot, the version of the compiler used, aka the first line of the listing, format like "V4.R5.M0 (Built:20170125)", and way more context of the source! |

Prino,
I am from production support so I do not have authorization to modify the code and test it in test environment. So I cannot display the data using PUT SKIP. I have requested development team to do it.
PFB the compiler listing. let me know if you need any more data.

| The only thing that is worrying is the fact that your compiler has not been updated for 8 months so it's out-of-date, and given that DFP instructions are now used in quite a few conversions, that might be something to look at. |

I am not an expert on compiler but just a thougt, if the compiler is out-of-date then the job should abend all the time. But the job is not always abending. It is abending randomly and it is running successfully after restart.
Our Development team is changing something and testing it. In the listing of testing code the version of compiler is V4.R5.M0 (Built:20160829). I hope the issue will be resolved. |

So what. My personal record. Error code created 1975. Failed 1989. The code failed to respond correctly to a rarely occurring data error. The code detected the data error; the response was incorrect. A designed in work around (which caused the program to run much slower) was available which immediately corrected the problem until a permanent correction was developed. |

| If you are in production support then you should not be worrying about this. It is the progammer's job to find and fix the error. Al you should be doing is verifying the correctness of the data. If it is correct then the program is wrong - not your problem. If the data is wrong - pass it back to whoever provides it and get them to fix. |

Instead providing any valid solution or any information that could help you are just saying which everyone knows. I never said that if the code is running for long time it will not abend in future. When I said the code is running for a 1 year successfully with same code, I mean the assignment statement for which the code is abending is not causing the problem.
If you do not have any solution or idea or any information then just stay away for this discussion. |

If you don't like replies then why hang in here. They are expert so respect their thoughts and experience. I am sure they have much more relevant experience than your age.
Moreover, if you disagree wait till you agree with some other replies or move on; You are asking here because none from your organization could able to solve it so be patient nothings always come at one go.
If I were you I could first try all the possibilities mentioned IBM0472S so did you do that? |
