Wow!  If this discussion about multiple job queues continues, it's quite
possible that my INBOX will get blown out!  Anyway, I've been sitting
back for the last few days in the few spare moments I get and have been
reading with interest this discussion.
 
Technical issues aside for the moment, I'd like to reiterate Jon Diercks'
comment that, as a system mangler (excuse me - manager), we often don't
have the time to go chasing after a user who, for whatever reason he/she
may have, regularly abuses "the system" by submitting lengthy jobs during
peak hours.  I also need to echo Chris Bartram's remark that the
management of system resources is what we do for a living -- enabling the
most number of end users to get the maximum usage out of a *finite*
amount of system resources.  It's been my experience that, no matter how
skillful a system manager is in setting up LIMITs or JOBFENCEs or is an
absolute wizard in using the :TUNE command, it takes only one ignorant or
(worse) devious end user to bring a healthy system to its knees.  And
don't even consider trying to "educate" the user about what they are
doing to the system (even if you had a free moment or two in between
putting out fires), because you'll just end up preaching the same sermon
to an inattentive audience.
 
Therefore, my vote has to go with giving the system manager (or delegated
operator) the authority to control (maybe "punish" is too strong a word)
those who regularly abuse the system by placing the abusers in a
low-priority queue. I think that Mohan's initiative is an excellent
starting point for giving system managers a greater flexibility in
managing their systems.  Regardless of the ultimate parameters selected
for multiple queue management, it should be first-and-foremost that this
is a SYSTEM MANAGEMENT tool.
 
End of tirade!!
