Re: Freaky occurrence involving a print file overridden to a PDF

I would contact IBM. or...

If it is two programs trying to create the same file, then maybe the
naming scheme you're using needs to be refreshed.

I know having written SPLTOOL over 20 years ago and creating PDFs from
spooled files I've seen similar things. When I create temp files I tried
once to use a timestamp.. not good enough.. that can easily cause a clash
too. So I always use incrementing data areas for naming unique files.

to use an IFS stream file as the body of the email (either text or html).

We have an externally-described print file, which I'll call FOOBAR. And

we

have a CL program that does an OVRPRTF to create a PDF that I'll call
/frobozz/pdfwork/FOOBAR12345.PDF (after having deleted any previous
occurrence of that stream file). Then, it calls an RPG program (I'll call
it FROBNITZ), that prints to that print file, generating the PDF.

Except that in a single freak occurrence, when the RPG program was

called,

it threw a CPF4208 message:

To module . . . . . . . . . : FROBNITZ
To procedure . . . . . . . : FROBNITZ
Statement . . . . . . . . . : 1000001
Message . . . . : File FOOBAR in FROBOZZ not opened.
Cause . . . . . : The open operation of file FOOBAR in library FROBOZZ
failed because of reason code 6: . . . 6 --
Specified stream file already exists. . . .
Technical description . . . . . . . . : errno = 3457.

and locked up the job.

But there isn't a "statement 1000001" to be found anywhere in the source
member or compilation listing.

I will note that FOOBAR is *not* USROPN, and its F-spec declares it as an
externally-described output file, of type PRINTER.

In the CL program, it's just
. . .

DEL OBJLNK(&PDFPATH)
MONMSG CPF0000
OVRPRTF . . .
MONMSG CPF0000
CALL FROBNITZ . . .

. . .

Near as I can tell, two jobs were trying to generate the same PDF at the
same time. Anybody have any insights?
