RE: stress testing

2004-01-05 Thread Poras, Henry R.



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 database 
related, though I still need to get all appropriate data. That means application 
server, OS (NTfor app server, Sun for Oracle), web server,... 
stuff too. I'm still trying to find what numbers the tool itself gathers, and 
if/how it analyzes the stuff. In the meantime, I've been reviewing some of the 
papers on orapub (i.e. Ratio Modeling, Predicting Computing System Capacity and 
Throughput).

Thanks.

Henry

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.

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 paper on
this last IOUG, but couldn't go and present it :(

RE: stress testing

2004-01-05 Thread Jared Still
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 patch consists of rewriting the loop with array.first/next/last
in a while loop to avoid the problem.

Yes, it is high level, but it can pinpoint time periods that you
may want to investigate.

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 and 
also to point them to somewhere  where they are able to get a copy
of it?  Dont want them hassling you and sending emails requesting it.
Let me know what you think

Be aware:  the script expects to use the standard oraenv and dbhome

RE: stress testing

2004-01-02 Thread Karniotis, Stephen
Henry:

   John is partially correct.  SAR, in concert with VMSTAT / IOSTAT, will
provide you with a wealth of information.  However, something is missing
from the equation here.  LoadRunner will generate scattered statistics on
overall performance of an application (sorry:  biased because Compuware has
a better tool), but misses the mark on what other things could affect
overall application performance.  For example, are you doing to perform a
virgin load test where no one is on the network and nothing but this
application is running on the client?  What about other traffic that would
affect overall performance throughout your enterprise network? What about
other applications/activities running on the client machines performing the
load test.  Only then will you have an effective measurement of application
performance in the real world.

   If you truly have to use LoadRunner, get some software that can measure
Network Performance as it relates to the load test and as it relates to
general network traffic.  The load test should account for other activity
being performed such as email, backups, file transfers, reading of
documents, etc.  Otherwise, your numbers will be skewed.

  Good luck.

Re: stress testing

2004-01-02 Thread Tanel Poder
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 concluded that the performance was acceptable.
But one of the components in Apps (forms server) started just hanging after
5-6 hours of usage in their system, so if they had done an automated stress
test over a weekend or even more, they'd have found it.

Also, any kind of testing should simulate real life, if possible -
otherwise you'll get results which might not match with future production
usage all. That means, the amounts of data should be similar, if you can use
a copy of real system for testing it'd be the best, also note that there
are probably different usage patterns in your future system (such as
month/year ending, campaign periods in retail businesses etc) so your system
has to cope with all of them.

Tanel.

 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 paper
on
 this last IOUG, but couldn't go and present it :(

 Subject: stress testing
 
 
 We are planning on running some stress tests on a
 PeopleSoft/Oracle/Solaris
 system starting next week (using LoadRunner). I have never
 gone through a
 formalized stress test before (most of my stress is brought
 about informally).
 So far I am planning to gather statspack information, and
 periodically get
 vmstat from the OS. Is there anything else that I should
 collect? Thanks for the
 help.
 
 Henry

Hi,

look for WinRunner. I think it does that stuff and is scriptable (of
course ;).

 Hello,
 
 Apologies for an off-topic posting.
 
 Does anybody have any positive or negative experience with any system
 stress testing tools?
 
 I do not mean DB stress testing (we have software fot that) but a test
 package for system with a fat GUI client?
 
 Need something that would simulate user input (keystrokes/mouse clicks),
 allow scripting, simulate multiple users and record results so that they
 can be analyzed later.
 
 Any info would be highly appreciated.

SQA robot is suppose to be one of the best.

Out of curiosity, what do you do on the DB end?

Do not criticize someone until you walked a mile in their shoes, that way
when you criticize them, you are a mile a way and have their shoes.
