Jared,
Are
you talking about yapppack? I've been using that for a while (nice display.
Though like statspack it is system wide so I usually just look for high level
stuff and changes). Not aware of a patch though.
With
most peoplesoft applications I have seen, the bottlenecks aren't
John,
Thanks for the tip. I've used sar and vmstat, but not in enough depth to have
any preferences. So far I don't have permissions for sar at this site, but I
should be able to get that.

The patch I refer to is one I made that didn't make it into
the most recent version of yapppack.
YP uses an array as internal storage, and walks through it
with a for i in 1..n loop. Since arrays are sparsely populated
there is a fair chance of hitting an array element that does
not exist.
The
Good catch on the array. I never noticed that.

Hi Tim
Tony Jambu here. Saw your posting to Oracle-l with regards
to your sp_vmstat.sh script. I am not sure if know but
I write a regular hints tips column for Select Journal.
I read your article and would like to mention your script and
point people to the script. Do you mind if I mention it
Henry,
I use the attached shell script to gather and store VMSTAT information in a
custom table within the PERFSTAT schema (i.e. schema belonging to
STATSPACK). Allows for some nice reporting over time, rather than
anecdotal here-and-there observations. Should work OK on Solaris, HP, and
Linux.
As the ultimate indicator of performance is response time, you might like to investigate YAPP
at http://www.miracleas.dk/. The data generated gives a good indicator of response time from
a database perspective.
If you use it, ask me for the patch.

Henry,
Sar is a better tool than vmstat/iostat as it collects a broad range of
information. Specifically, sar -q should show up CPU queueing and swapping,
and sar -v will show up file/process table overflow issues that may occur
during stress testing. IMHO, sar is quite underutilized ( had a

And when you're doing stress testing, make sure you load your system for
quite long time.
Stress testing shouldn't only verify system performance, but it should also
test system's reliability.
One of my clients had a problem with Oracle Apps, where they did a stress
test for just one hour and
