Re: Run priorities on Tomcat server jobs

The CHGJOB will do it regardless of the job class.

By the way: any priority under 10 (console) is considered really stupid in most places. Since that job runs with more priority than the console, stopping a runaway will really be interesting. They seem to really not understand work management.

That also means the user running the job has a maximum job priority on the user profile set well below standard.

The job priority is determined by the job description and the routing

quite the concern, but on older boxes has a significant effect).
So first what job description is on the job then check the routing
data which will determine the job class. The class has the initial
priority.

I have some further information.

It seems that the catalina.sh shell script itself sets the RUNPTY:

if $os400; then
COMMAND='chgjob job('$JOBNAME') runpty(6)'
system $COMMAND
# Enable multi threading
export QIBM_MULTI_THREADED=Y
fi
