The below questions were asked during my interview.
1) Job1, job2, job3 are using one common program. Each job executes this program for it specific process. How would you find/know which job is using this program?
2) Changed map field length and the corresponding program also changed. By mistake, moved program only to production. What error will occur while accessing this map/program?
3) Record length 100 is defined in File Description. If I move 200 length data to that record field, what error will occur?
4) What error will occur, if move data to column field in DB2 table. Data size is larger than column field size?
5) Select 'abc' from table table_name, what will it return result. If 'abc' value is in the table.
Can anyone please answer to these questions?
Thanks |

A simple search in all the libs with search string as 'prog name' provides you the list.

Hi,
I think interviewer was asking if the JOBs are 'running', at that given moment which JOB is using the load module of that program...
...just a different perception about the same question. |

Hi Murali,
I didn't get You, what do You want to convey here?
BTW, if I go with my assumption, I'll say, LOD modules are with DISP=SHR, who is bothered to check which JOB is using the LOD module. I don't think that interviewer wanted to listen about the ISPF 3.14 option. |

If u move the changed program with out staging in to the production, during AUDIT process you will get SYNC10 or SYNC12 error |

Just the 'abc' literal you specified.....
Note: the 'Truncation' answer assumes COBOL.... |

Using the command "/DISP A" in the corresponding online region we can get the details of the JOBs running and the programs they access. |

If there are n records in the table, the literal 'abc' would be returned n times. |

Anuj, interviewer has asked the same.
Thanks all for the answers...
I told to interviewer that truncation error. But, he was asked the specific error message/code...
Thanks |
