Back on V7R1 we had a process fail because there was a ended job with spool files with the same JOB/USER/NUMBER as the new job.
The duplicate job was from a few days prior and it still had spool files.
The new job failed because the commands couldn't figure out which job spool files it needed to deal with.
So, The job/user/number is Not guarantee unique.
It's like winning the lottery. Sometime, somewhere, it's going to happen.
It's just highly unlikely.
If you add Job Date, then you get closer to having no collisions.
If your system is cycling 999999 jobs in the same day, then you might want to find the offending process and rewrite.

There can only be one entry for job/user/job number in the job table,
therefore unique.
The internal ID is another thing entirely and is cross referenced as part of
the job table.

Jim,
If you look at the message data on
DSPMSGD RANGE(CPFA98C)
you will see they meant
<snip>
the fully qualified job name:
" is the Qualified Job ID (Jobname, User, Jobnumber) unique to the system?"
</snip>
28 characters is
jobnamexxx/userxxxxxx/######
10+1+10+1+6
The internal id is only 16 characters.
CPF0906 is the one returned for simple stuff like ENDJOB jobname or WRKJOB
jobname Telling you to qualify it.

I think the question was about the fully qualified job name:
" is the Qualified Job ID (Jobname, User, Jobnumber) unique to the
system?"
In that case yes it is, with the exception of if you roll over job
numbers,
meaning they get past 99,999, and you have really really old spool files
out
there that might have a job number, then the system will skip that number
and move on to the next one.

No, the simple job name is not guaranteed to be unique.

Hello,
is the Qualified Job ID (Jobname, User, Jobnumber) unique to the system?
Or is the internal Job ID unique?
Best regards
