Hi all,

This question is asked in GE interview. If we have 5 lakhs of records in a COBOL file. and 1 record corrupted then quickly how to find out the corrupted record. I said that using FILE-AID we can find it. If you have more methods please explain them..

Thanks,
Reddy

use file-aid compare or use "superC" for comparing the old and new file to find the corrupted record.

In VSAM we found defect records some times,because we were done more times update and deletes.For these we use REORGANISATION.If we want to found defect record we follow one method.That is We take one empty VSAM file we are load that vsam file into empty vsam file If any defect record is there load is showing error.AT that time u go to spool it shows u how many records are loaded.When defect found loaded error will occurs.U found easily that record.In spool it shows u count of loaded records.
