RE: ECOM170 system on the blink

Dwayne,

Can you clarify about the system kicking you off?  I am assuming you
mean that while signed on you session might hang or you get kicked back
to the signon screen?

Most of the time poor system performance comes to very hot cpu, memory
demand problems, or disk performance.  Sometimes these can be affected
by a single bad job.  As your system is in a slow period I would check
the CPU utilization (either through WRKACTJOB or WRKSYSACT), memory
demand via DSPSYSSTS, and disk utilization via WRKDSKSTS.  Are you
running any performance data collection during this time frame?

CPU - look for jobs taking a high level of CPU%, especially those jobs
with a high run priority like an interactive job.

Memory - check your page fault numbers.

Disk - look at your disk drive utilization.  See if it is high - this
could even just be one drive.  I don't know what is normal for you so
you will have to interpret the results yourself.  

If you are having interactive jobs ending I would inspect your job log
for any information and possibly also check the QSYSOPR message queue
for anything that might look suspicious.

Also, when you indicate slow I am assuming that interactive response
get's sluggish?  Batch jobs seem to be running ok?

Good Morning,

 

 

Our ECOM170 box has become slow at time and it sometimes kicks us off
the system.  We check the system status and we are at 77 %.
