FWiW: The requirement is specific to which UPDATE and/or DELETE rules
are defined for the relationship. [As such] The Database Programming
Guide describes the requirement in the section "Specifying referential
constraint rules" under the heading "Ensuring data integrity with
referential constraints".

"Pg 254 System i: Database Database programming
Details: Specifying referential constraint rules — journaling requirements:
If you perform insert, update, or delete operations on a file that is
associated with a referential constraint, and the delete rule, update
rule, or both are other than *RESTRICT, you must use journaling.
You must journal both the parent and the dependent files to the same
journal. In addition, you are responsible for starting the journaling
for the parent and dependent files.
You can start the journaling for the parent and dependent files with
the Start Journal Physical File (STRJRNPF) command.
If you are inserting, updating, or deleting records to a file
associated with a referential constraint that has a delete rule, update
rule, or both rules, other than *RESTRICT, commitment control is
required. If you have not started commitment control, the system starts
and ends the commit cycle automatically for you.

Where does it ever say in any of IBM's documentation that you have to
use the same journal for all files that are using referential
constraints?!? We just started using ref. constraints and just
realized the problem when we started getting:
CPF523C - Referential constraint journal error. Recovery: Change the
files so they are journaled to the same journal.
If we had known this ahead of time, we would have planned for it, but
now we have to change our whole journaling concept!
