How can I be sure that that is the case?
Because it is the case. Tell them "Simon says" :) Interactive capacity
is not exceeded by non-interactive work--except for the rare case of
twin-ax attached printers.
I need to show management what this
issue is and make suggestions how to resolve them. If 10 users open
up 40
session, even if the sessions are not used, could this cause the
problem?
Unused sessions are unlikely to be contributing except during the job
start process and this can be a significant hit. Sessions that are
just sitting in DSPW will not be contributing. However, one has to ask
if they're not being used why are they being opened?
Error recovery in a subsystem monitor that is handling interactive
work can also contribute.
I want to make sure its not a program loop or something.
It's not that unless you have programs looping in multiple interactive
jobs in which case I'm sure you'd be hearing about it from other
sources.
I need something to show management.
Get yourself a copy of "Aiming for Zero Interactive on iSeries". It's
a PDF published in 2003 and lists the things that contribute to
consuming Interactive capacity.
Start the Collection Services (use Navigator). Let it gather data. Run
CRTPFRDTA to load the performance database files. Query the QAPMJOBMI
file using the query shown in that PDF. This will show all the jobs
that have consumed interactive capacity during the monitoring period.
