RE: Compare Files/Records -- MIDRANGE-L

John,
I recently finished a Y2K project where we compared files during the
remediation testing.  We found TAATOOL's CMPDBF utility to be more readable
than CMPPFM.  However, one cavet, and this may be true for any software, (I
would check the $5000 one) if one of your programs deletes a record or adds
a record and the parallel program does not, then neither tool will compare
the records beyond that in the file correctly since it is comparing by RRN.

Another idea, if you have the system resources, is to begin journaling on
all files, run a short series of tests and save the journal files after each
of these tests to DB files and compare the journals.  If both systems are
functioning the same, then the journals should be identical.  If not you
have detailed log of what changed, when and where.  You will probably want
to run short tests and delete the journals after each because journaling 500
files could eat up disk rapidly.  If this is a production environemnt, you
may be concerned about extra overhead journaling will take up.

Good Luck,

TAATOOL has a utility called CMPDBF that may do what you want.  I seem to
remember using it several years ago.  You may want to check it out before
buying a product.
