Have you had a look at the VALIDATE_DATA_FILE Table Function within the
SYSTOOLS Schema?
https://www.ibm.com/docs/en/i/7.5?topic=us-validate-data-validate-data-file-
validate-data-library-table-functions
Otherwise you may run the following query ... if it does not return any row
both tables are identical:
(Select * from Table1
Except
Select * from Table2)
Union
(Select * From Table2
Except
Select * From Table1);

Subject: Comparing Two Copies of a Physical File
I need to compare the results of two different programs, as stored in the
same physical file. I have saved copies of both iterations, but am trying
to figure out how to do a field level comparison based on a keyed record
join.
I'm trying to avoid an SQL with a select based on differences between fields
in the two files because there are 54 fields in the format.
TAATOOLs has a CMPDBF command, but it's an E1 file with null value fields.
In the case of nulls, I would want no comparison if both versions of the
field in question have null values.
Z/OS has a compare utility, but I can't find a match on the i. CMPPFM won't
work because the files are way too large.
Is there a way to do this without a massive SQL statement comparing at the
field level with 50 fields to compare for possible differences?
