Re: journals

Hi Katy
You don't say that the barcode labels are for, but presumably there would be a problem if any went missing. Do you need a history of which labels have been printed?
If there were no journaling, would it be possible to work out from the existing data what labels were required and what should be on them?
If yes, then the existing files should be being journalled (IMHO) and there is no need to journal the same data twice.
If yes, but the existing files are not being journalled, and the history is important, then it makes sense to journal them before printing them as journalling is much quicker and more reliable than printing.
If no, it may be an unusal way of doing things, but not too terrible. Personally I would write the label details to a file and then journal the changes.
As for the journal sequencing problem, I have used journalling since System /38 days and never had a problem, so something must be wrong with the setup. Do you reset the journal sequence number ever? if so this could cause your problems.

Hello everyone,


I need opinions.  I have been an RPG programmer for 20 years.   I still see
things I've never seen before but this one doesn't make any since to me.


I have been programming for a manufacturing company about 1 year now.   The
company had some IBM guy to come in and develop the barcode label and place
the record into production (MAPICS).    Before the label is printed it is
first journaled into a journal with the journal receiver etc....,  then
received from the journal and sent to a program that prints the bar code
label. 
Now, I was always taught that journaling was only for backup and recovery
purposes,  which I know what some people will say,  that he designed it this
way incase there was a disaster and the records could be received but,
wasn't there a better way to achieve this.   It appears to me that this way
would be cumbersome,  eat up the DSAD of the machine and he is journaling
the record first  and receiving it back before he prints the label.
Shouldn't he have at least printed the label first before he journaled the
record.   I just want your all's opinion about this design.  Maybe there is
something I don't see here but the journal sequence goes haywire all the
time and we have to reconstruct it.     EVERYBODY, ANYBODY GIVE ME YOUR
THOUGHTS ON THIS?????
