there's the easy way to control resource usage, IIRC this can still be
done with WLM and workload resource definitions, been some time since I
worked in a shop that had defined all the mainframe resources and used
scheduled environments and BMC's CONTROL products to manage workloads
based on what resource was available and what LPAR these resources are
defined
Thru-put manager is a great product and the JAL language of how to setup
rules was pretty easy
very hard, an outsourcing shop I worked at where a combination of JES2
exits, CONTROL-M and querying the EDT, then pass the eligible devices to
CONTROL-M to manage ALL workloads, tons of places for errors, worked
great when it worked, most scheduling systems have a way to define the
resources for the LPARS and managing what runs were, and when is not so
hard

Does UNIT=(TAPE,,DEFER), or perhaps AFF, make a difference?
JES2 or JES3?

Of course it would. But these days there are many folks that just know that
they have to get a job done, not necessarily how to get the job done. Just
like coding DCB and space info anymore, this is another one of those things
that should be able to be externally limited.
