Thank's to all who helped with GENUUID(). It's working great!


With respect to the latency warning, are you referring to potential
performance bottlenecks, or a risk of duplicate ID's?

Your warning did get me thinking, so I decided to run a crude little test. I
created a PF with a single field to store the UUID value, and no primary
key. I then created a program that called GENUUID() and wrote a PF record
with the result, for 5000 iterations. The program was submitted to three
different subsystems (jobs held) and all three were released within a second
of each other. It took about 8 seconds for all jobs to complete. Finally, I
did an ADDPFC TYPE(*PRIKEY) in order to test for uniqueness. Everything
worked just fine.

Do you think my test was too simplistic?
