We must live right. We use PDSE libraries for most "production" libraries
(load & "sysin"). We have have _no_ problems. But I'd be willing to bet
that is because we are a single system "sysplex" with little sharing. We
used to be a two system basic (not parallel) sysplex, but did not have any
problems then either. Likely because all updates to the PDSEs were done on
a single member of the 'plex.
Where I work, we run parallel sysplex. We have multiple LPARs in
the main sysplex and it was decided to make our Load Libs PDSE
some years back (perhaps z/OS 1.13?).
However, I've experienced a PDSE failure using z/OS 1.13 at a
different shop. Thankfully it was a PDSE holding listing members
and not the source members. I also lost the Loadlib associated
with it. So I can appreciate the angst.
With the changes that IBM has made to support PDSE, we have not
had, that I am aware of, any PDSE failures since I was hired.
Meanwhile, I am a bit concerned that problems are not being
addressed in COBOL manuals, even if they are "small" or
"insignificant" problems.
Those insignificant DOC problems cause headaches for people
writing code to do translation. The difference is, I recognized
immediately how wrong this was (I'm not doing translation, but
something related).
Now, for INSPECT TALLYING and EVALUATE, I had to go to a third
party's explanation to get my COBOL code to work. Yep, I had to
go to a Fujitsu COBOL manual to get an example. The one I had
when I was writing SMF code on a W/NT 4.0 box many years ago.
Mind you, not the first time for me to use either verb, but there
was some interesting things I needed to do and the COBOL 4.2
manual just didn't do it for me. One look at what was said with
the Fujitsu book and I recognized how I was misreading IBM's doc.
