Natasa,
you didn't say what your definition of "lowest priority" is. Since years
we have a constrained system with capping periods and the same problem as
you, that batch gets more CPU resources than expected, even during
capping. What we see is that Online workload doesn't match it's goal and
Most times "wrong" WLM settings lead to problems in stc's getting dispatched
incorrectly. Is "online" running longer on a transaction basis or how do you
know that online is being hurt by your low prio batch. If you problems persist
you can send me some smf data and then we can talk in more deta

You are starting way too late. Living beings are the way the protiens
in the primordial soup have created to replicate themselves.
Sometimes the replicated protiens are slightly different, and most of
the altered protiens don't replicate as well and a few protiens form a
competing branch.

I have to disagree. I often hear this, but there's no "resources" to give.
Other than MPL adjustments, almost all of the major WLM decisions are simply a
matter of setting dispatching priorities. There can never be a situation of

Why do you want to get rid of the CTC connections? Do you need them for
something else?
Are these SCTCs or FCTCs? If yes, there are times when these may be faster
than the CF.
I also recommend 3 Transport Classes: 1K, 8K and 20/32K, with the last one
being the default.

It's really not more complicated. Higher priority work always gets the
computing cycles it needs, except as it relates to competition at the same or
higher priorities. Low priority cannot contribute any resources, since it
doesn't have anything that higher priority work needs.
In other words,
Gerhard's generic point is well made, but the chicken-egg situation is
in fact very complicated. One of the most widely quoted apothegms
most widely quoted among modern evolutionary biologists is Peter
Dawkins' (or perhaps Samuel Buitler's)

If you want to think in those terms, fish existed before birds. And fish
lay eggs (caviar?). So the egg preceded the chicken. Come to think of it,
arthropods may have preceded fish. And they lay eggs too. Eggs came way
before chickens. A chicken is just a "right sized" dinosaur.
