Hi ,

Problem statement : Need to find out if a person (First name , Last name and DOB) has more than one unique ID. A person can have more than one record in the file.

Solution approach : Copy the file and use it to match against the original file using the key value (First name, Last name and DOB). If Key values match write the two records (Original File and Duplicate file) consecutively in the output file. Later using INclude condition , compare the Key values, write the record if it has different uniuqe ID's.

File lay out (Starting position, Length) : FB , LRECL = 206

Partition number : 1,5
UNique ID : 6,10
Other Fields : 16,86
Last NAme: 102,60
First NAme : 162,35
DOB : 197,10

Help required :

Both the files which am comparing have 488948457 (488 Million records) each. This job abended stating ABEND=SB37 U0000 REASON=00000004

1) Will i be able to compare such huge files using SORT ? or is there any better solution approach to my problem statement

Thanks in advance for you help

Why are you estimating at 10 billion records when you "only" have 488m? Why are you estimating anyway?

Why do you want to write all of your data, not just the matches?

You are SORTing the data twice. Each time you attempt the job. If a massive JOINKEYS needing the same file twice, SORT to a permananet file in one step, use that for both JOINKEYS with SORTED,NOSEQCK.

No, you don't need JOINKEYS. .

Have you contacted your site support group? The SB37 indicates a storage problem and your site support group would be the best group to help you resolve such issues.
