RE: Creating a physical AND Logical file

You make a good point here with your example of forgetting to apply QTEMP,
but part of unit testing and program walk
Again - we agree to disagree

My 2 coppers...

There are times when it may be necessary to allow temporary objects
inserted first in the LIBL.  Since all programs would have to be
modified & hard coded to QTEMP (or any other intermediary library for
that matter) it just makes more sense to leave the programs where they
point to the first library with the object.  I prefer not hardcoding at
all (and this can be done...so why make life harder...).  Can YOU
guarantee that a programmer will not forget to override to QTEMP when
they should be??? And if they did...how long would it take to discover
that error & then patch the data that got inadvertently got
updated/deleted/added to the actual production files??


Thanks,
Tommy Holden

This is a valid question. What reason would you want QTEMP on top of the
library list? I'm curious at the reasons why.

Guarantees are a dime a dozen until a problem happens... However, I
think I would feel pretty comfortable if the problem never occurred in
37 years... Then, if it did occur, I would attempt to fix the problem,
which would not be to move QTEMP.

It looks like we will agree to disagree. Since QTEMP is at the bottom
there was no further "weird" problems. Would this happen again? Who
knows, but changing the library QTEMP to be at the bottom will NOT
create this same problem again in the future. Can YOU guarantee that
this situation will exist?

Sounds like a programming error to me... And then the baby got

thrown

out with the bathwater - instead of fixing the bathwater...

Dave - with users signing on the first thing in the morning and not
signing off till they leave (sometimes they forget) and doing a
multitude of tasks throughout the day, creating a multitude of
temporary files form different jobs that they run, QTEMP will always

be present.

Now the chances that a file created in QTEMP from a program written

by

programmer Fred Bloggs has exactly the same name of a file from a
different program written by Joe Schmo  are slim, however, that

being

said, I can verify that in one of my earlier positions, this has
happened three times. The first 2 times, we couldn't duplicate the
problem the user was seeing. The third time we drove over to her
office and lo and behold, the program was picking up a temporary

file

that had been created in QTEMP (which was at the top of her library
list) with the same name as a PRODUCTION file in the PRODUCTION
library list. At that shop it was determined that QTEMP should be
placed at the bottom of the library list, and if a temporary file
needs to used, define the library name QTEMP as well.

I guess in 35+ years I've never written ANYTHING that expected

QTEMP

to be anywhere but at the top. Currently we create application

data

areas that are created from template data areas in "production".

The

QTEMP ones are changed to match the current needs of the job. Job
ends

- data areas gone. No *LIBL issue at all. If QTEMP doesn't contain
information that is supposed to be unique to that specific job I
don't

see any other purpose for it.
