Bob,

 The original poster (Shalom) was suggesting that the fact that data can be
changed during runtime between the time the record is read / processed by
the program and the time the record makes it to the database (and journal),
there is a possible security hole. 

 I don't think that it is.

But in the case below, isn't the Journal accurate?

Program reads in database record.  Pgm changes data, hits break point before
the update is issued.  Person uses CHGPGMVAR to change one of the fields and
then resumes execution.  Record update is done.  Journal accurately shoes
what the data was when the record was written/updated...AFTER the chgpgmvar!

Not seeing the problem.

Bob

 You are also required to have at least *USE authority to the target job's
*USRPRF.  So, if the system in question has a gaping security hole
(allowing the user to debug the job in the first place), I wouldn't expect
IBM to log all changes to the journal, especially since those changes were
to memory, not yet in the database.

I started a debug session for another job, using chgpgmvar I changed a
program variable that was due to be written to a database file and then
I
looked at the journal.
There was no trace of the fact that the job that wrote the modified
value
was interrupted in any way.
This looks like a problem, doesn't it?

Only if you put debug versions of your objects into production.
