One thing that I haven't seen mentioned is that converting from EBCDIC to UTF-8
is that some characters in UTF-8 are 2 or 4 bytes, thus changing the lengths of
fields.

Some others have answered your questions, but here's my $0.02 USD:
1. You should convert all the numeric fields to edited text. Otherwise, unless
you're using a COBOL system on Linux, you'll have t

it. That means you must have an IMS system to run it on.

Each segment must be its own table with the combined key that includes
the key of the parent in parent order.

So if you thin
Jason and all,
Attila words are wise, but there is more.
From your email, I'm not certain if you are talking about one data base
or a collection of data bases.
It's good that you have an image copy (copies) and apparently the DBDs,
but there is more to it.
Do you know if your data bases ha
Jason, your applications will be in for a big surprise if you follow this
conversion path.
For example, PIC 9(4) COMP is a binary numeric field which is BIG ENDIAN on
mainframe, most (but not all) LUW and cloud systems are LITTLE ENDIAN. So
you need to convert these fields, otherwise the numbers c

You can process the unload file if you know the record format. This, the
record format, depends on the utility used to perform the unload. Once you
have it, map the segment name to segment layout from the copybook. If you
have easyTrieve installed, you can convert the copybooks to offset bas
Dear Micael and all
Thank you very much for your response and the valuable information provided.
Over the past few days, I discussed the DBD definitions with our IMS DBA, and
we have a similar setup
where “The only fields that are required to be defined in a DBD are the keys,
indexed fields
