Re: HTTP API or Web Service concurrency issue

In our case, these letter documents created in the IFS are associated to a
unique identity column value, so a very simple fix for us will be to use
the unique identity column value as part of the IFS file name, coupled with
a document type identifier for future use.

Still bad idea, even to 100 places. :)

Easy? Yes, but not a good idea.

While RPG only gives you 3 digits precision on timestamps...

The OP mentioned he was using SQL to get 6, which it's always supported.

Actually, with SQL you can go all the way to 12 now...and RPG will work
with them. It just can't generated them.

Well, milliseconds is not a lot of precision - just three decimal
places. OP mentioned that he tried six places.

I agree with the sentiment that you cannot rely solely on timestamp to
ensure uniqueness, period. But I think the problem is possibly even
worse than meets the eye on IBM i systems, because even if you try to
get six places, the system (or perhaps the language) may only give you
three. I know for sure that I tried testing timestamp resolution in
RPG years ago, and only got down to milliseconds (any further digits
were all zero). I don't know if it's still the case on more recent
versions.
