And poorly designed applications that dynamically
request the same resources exclusively, but in a
different order in various separate instances.

Theres a possibility for some to even get into
deadly embraces where 2 jobs lock each other out
and can never finish because each is holding
resources that the other needs. Nowadays with
scheduling packages and other advancements this
is not common but in the past it was frequent.
We run with Delay so jobs of the same name

Subject: EXTERNAL EMAIL: JES2 JOBDEF DUPL_JOB=NODELAY - Any gotchas?
I am not a sysprog but I occasionally play one
in my spare time. I am thinking of changing a
system that I control to DUPL_JOB=NODELAY. Any
gotchas? Anything I need to consider before I do
this? Do most/many of you run with NO_DELAY?
I am trying to solve a problem where I have jobs
delayed because the names are duplicates. I can't easily change the jobnames.
I can't think of any issues. We don't have any
significant automation. I can't think of
anything where jobs are referenced by name rather than Job ID.
What should I be considering?
Thanks,
Charles
