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

The name was already long enough. Document ID and a couple of reference numbers (PO, etc.). We appended -YYYYMMDD-hhmmss-###.

The problem with horsepower 😊

Timestamp + GUID is a nice combo although results in longer file names.

Same issues happen on other platforms. In .Net you can go out to seven millisecond levels: yyyyMMddhhmmssfffffff and we still ran into issues when fast Windows VMs came along.

Timestamp + GUID. Problem solved.

I recently had a project to create files to send to an Oracle system. They said "just use a timestamp for uniqueness". Well.... as Brad mentioned, not good enough. I, too, added a sequence # to the timestamp name generation.

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.
