Re: ECOM170 system on the blink -- MIDRANGE-L

To check if the system as decided the battery is 'dead' is easy...
WRKDSKSTS and then F11. Status of DEGRADED is a 'dead' cache battery. 

WRKPRB should also have SRCs of xxxx8008 or xxxx8009 with xxxx being the 
controller card feature code

I wish IBM would make this easier - to have to get into SST is too much.

Hello,

This is what our operator says:

Two things are happening that I have noticed. 1-some batch jobs are
coming out to execute at a RUNPTY 10 and high time slice. 2 - We are
running performance collection.  I am trying to change job priority as I
see them running.  The only thing on the system that runs at a priority
10 is DSP01.  If anything runs equal to or above that we could possibly
have a situation where the DSP01 could be non-responsive.

You might check the job logs of those jobs that ended just to see what
they might indicate.  It could be a failed cache as mentioned else where
or a rogue job or situation.  I'd check on those items I mentioned
before and see if you see anything out of the ordinary.  WRKACTJOB is
not the most accurate but if you don't have WRKSYSSTS (comes with
performance tools) it will have to do.  Open it, run it for at least a
minute, sort it by CPU utilization and see what you get.  On DSPSYSSTS
look for high fault rates or any wait-inel numbers.  On WRKDSKSTS look
for high disk utilization - one disk or many....again, not knowing what
you have normally makes it hard to say what would be bad.  In my world
all of my drives operate under a 15% utilization.  Just don't take a 5
second snapshot - let it run for at least 60 seconds or more.

Can you clarify about the system kicking you off?
1) I did a DBU on a file and it tried to open the file and after five
minutes of trying to open, my session ended.  I had to log back on again
2) I was coding a program in one session and went to another session to
check a spool file.  I put a 5 on the spool file and after about 3
minutes of trying to open the spool file my session ended (both of them)
3) I was trying to look at a 2 page spool file and it took about 5
minutes before it opened.

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 %.
