RE: Restricting QZDASOINIT jobs

Thanks, Charles.

It's not that I want to see QZDASOINIT jobs at less than x% - it's because they are having a bona fide impact on the system. We've been struggling with this forever - we can optimize the sql statements until the cows come home but it doesn't seem to make a difference - QZDASOINIT jobs consume a significant amount of CPU cycles.

We're actually going to move to a different ODBC driver from a third party to see if that solves the problem. But in the meantime I'll read over the documentation you included and we'll see if it makes sense to implement.

Thanks!

At 7.1+ you can assign "workload groups"
https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/IBM%20i%20Technology%20Updates/page/IBM%20i%20workload%20groups

But only useful if you're running a multiple core machine.

Why do you want to do this?

Assuming your CPU isn't at 100%, all you'd be doing is artificially slowing down the work being done via ODBC. It won't speed up anything else.

Do you actually have a problem? Or do you just not like seeing QZDASOINIT using 50%?

If you actually have a problem, you can adjust run priority, memory available, max active, ect ect to provide more resources for non-ODBC work.

Hi all,

A while ago I moved all of my ODBC spawned jobs into their own
subsystem (which I conveniently named "ODBC"). Is there a way I can
restrict how many resources they consume? Whenever I look at my
system status the QZDASOINIT jobs seem to hog a lot of resources (in
excess of 50% CPU utilization). I'd like to restrict them to using a
cumulative percentage of less than 25%, but not sure if it can be done.

Thankee-sai!
