Is there a chance that the file is cached? Check the status returned for the 
request and see if you are getting a status of 304. If so, the server is not 
downloading because the request you sent indicates there is no need to 
download the file since it is cached and current.

[Tam W. <tam...@te...>]

Hello Dan and Bernie and the list,

Thank you both for your quick responses.  I won't be back on this work
until Friday so will investigate more then and report back.  =20

The following is further info, but no need to respond to it unless
something obvious jumps out to someone.  First priority is for me to
retry it.  It will help a lot knowing that it should work.
=20
----------

I must be doing something different or not understanding something as my
code looks very like Bernie's example.  And I have tried with and
without SYNCHRONIZE REQUESTS and with and without LOAD RESPONSE_INFO.
However it is worth me repeating these tests as I was experimenting at
the time and might have got something wrong. =20

My file takes at least a few minutes to download manually vi IE (13Mb)
but in OpenSTA it is only reported as a few seconds. =20

I tried the LOAD RESPONSE_INFO only because I thought that way I could
see how much of the body I was getting.   I could only get (log) the
first 5 bytes of the file. But the 64Kbytes limitation might mean that I
was shooting myself in the foot with that idea.  I will try not using
the LOAD RESPONSE_INFO.  =20

Another idea... Perhaps it is because I have only tried it in the Run in
the Test Modeller and the Single Step in the Commander, OR not let the
test run for long enough for the full download to occur.  I see in the
single step log it says something like 'binary body' and implies it
won't therefore show it in the log.  I will try a full (not single step)
test run with code like Bernie's and run it for long enough for the full
file download to complete and check what value the timer returns.
=20
As you pointed out I don't really need to wait for the GET to finish, I
just want a timer value which is the download time (to the last byte of
the binary file) and more importantly I want the full body being
downloaded through the proxy I am testing (rather than the connection
being dropped) so that it experiences all that load.

I'll report back on Friday.  I appreciate your help.

Regards,
Tam

Bernie, thanks for the catch on the syntax!  Think I momentarily confused

The essense of what Dan said is correct however the proper syntax of the 
command is 'SYNCHRONIZE REQUESTS'. You don't need to use ''Load 
response_info' to get  OpenSTA to wait until the binary file is downloaded 
before proceeding with script execution. The only reason you would load 
response_info body or header is if you wanted to examine the response  and 
keep in mind that with the version of OpenSTA you have, you are limited to 
looking at the first 64K bytes of the response. The synch command will cause 
script execution to pause until the entire file is downloaded (not just the 
first 64K bytes)

The following code fragment will do what you want and time the event as 
well;

  Start Timer BINARYDOWNLOAD

  GET URI "http://www.iperformax.com/BernieVelivisResume.pdf HTTP/1.1" ON 1 
&
   HEADER DEFAULT_HEADERS  &
   ,WITH {"Accept: */*", &
    "Referer: http://www.iperformax.com/about.html", &
    "Accept-Language: en-us", &
    "Connection: Keep-Alive"}

 SYNCHRONIZE REQUESTS


  End Timer BINARYDOWNLOAD

Tam, you should be able to accomplish this binary download with opensta.  If
you want to have the behavior be that the next GET after the download waits
til the file is downloaded (though not sure why that matters--you can put a
Timer around the binary download PRIMARY GET and time the download
irrespective of what else happens downstream), try inserting a SYNCHRONIZE
ALL after the last GET URI following the PRIMARY GET URI that triggers the
download -- this will cause the script to wait until the PRIMARY GET and all
subsequent GETS to execute before continuing.

[OpenSTA-users] Can a script wait until the end of a HTTP Binary file download completes before continuing?

[Tam W. <tam...@te...>]

Hi,

I am using the OpenSTA toolset for testing a Web Proxy rather than a web
server.  I want to use the tool to generate HTTP load.

One of the forms of load on a proxy is http downloads (mostly of binary
files).

Can the OpenSTA toolset simulate a real world HTTP binary file download?
In particular will a VU script wait until the end of the file download
before continuing with the next GET request in the script?

I have managed to record a script which downloads a word document file,
but even though I have tried to use,
LOAD RESPONSE_INFO BODY ON 1 INTO MyBody
I am fairly suspicious that TestExecuter isn't waiting for the full file
download before the VU script finishes, it seems to simply wait until it
gets the 200 level response and the first (of many) packets of data.

I'm fairly sure I'm not suffering from the issues/bugs in the FAQ to do
with the LOAD RESPONSE_INFO BODY call failing (which I worked around by
loading the HEADER first), because I get a status of 0 and I can log the
first few bytes of the body.

Any help gratefully received.  Happy to send more detail if I'm not on
an impossible path.

[OpenSTA-users] Connection reset by peer

[Himadri C. <him...@ya...>]

Hi,
I am getting the following message when I am recording
a script using OpenSTA modeller. The application is a
.NET application and making AJAX call.

forcibly closed by the remote host. This normally
results if the peer application on the remote host is
suddenly stopped, the host is rebooted, or the remote

[OpenSTA-users] Using OpenSTA for test web applications using JSF pages

[<gn...@fr...>]

Hello,

I'm trying to use OpenSTA to test a WEB application using JSF pages.
For a sample id user, I get (or post)  very much parameters (more than 30) .
Following my context page,
These parameters are reloaded at each page access with more new different
parameters corresponding to the id user.
To replay the sequence I need to use the same number of variables ?
Can I use another method?
All experiences using the JSF pages can help me.

Thank you very much.

Rob, everything looks right here (assuming "opensta" is the first value
in
your file), *except* that you need to change the scope of fileuser to
GLOBAL--so that *all threads* (aka v-users) share this file and get the
"next" value as you expect.

Also, you may trip on the known issue of "cached .FVR files", where new
values you added to fileuser after creating the variable "disappear".
To
resolve, delete the cached files in F:\OpenSTA\Engines\Temp.

[OpenSTA-users] Virtual users not heeding the Mutex

[Hurkes, R. <rh...@fo...>]

Hi all, I am trying to get my script to work and I am having issues
using the MUTEX function. I have a file called list.FRV which has 5
usernames in it. From the FAQ and the mailing list, I made sure my SET
is within the MUTEX, and I believe the scope is correct for what I'm
trying to do.

	CHARACTER*512 fileuser, FILE =3D "list", SCRIPT
	CHARACTER*100 user, LOCAL

    	ACQUIRE MUTEX "LOGIN"
		NEXT fileuser
        	SET user =3D fileuser
		LOG "User: ", user
	RELEASE MUTEX "LOGIN"=09
=20
	PRIMARY POST URI

When I run the test, I get in my log file "LOG: User: opensta," for all
of my virtual users. I want VU1 to take the first entry in list.FRV, VU2
to take the second entry in list.FRV, and so on.

Re: [OpenSTA-users] Stalling on HTTP to HTTPS+AJAX

[Hurkes, R. <rh...@fo...>]

The "SYNCHRONIZE REQUESTS" is something that the recording gateway adds.
The connection should not stay open.

I turned off https on my server and I was able to record everything
perfectly.

I was able to record other parts of the site that were "HTTP+AJAX" and
"HTTPS without AJAX" and they both worked fine. So it seems that the
problem is specifically with HTTPS+AJAX as I originally surmised.

When it hangs in the recording process, this is what I see:


IE address box says: =
"http://%7Bmyurl.com/UI/Customer.aspx?p=3DShipping&"

The information bar at the bottom of IE says:
"(23 items remaining) Downloading picture
http://{www.myurl.com/Images/indicator.gif...."

Rob

Hi,

just a wild guess:

Is this the kind of Ajax-Request that keeps the connection open so that
the server might push more data later? This would contradict the
"SYNCHRONIZE REQUESTS" as the connection will still be open. I don't
know if this would be handled by the recording gateway or if it's
introduced later by editing the script...

Also, you might want to try eliminating https in this case, just to
confirm if the problem is in https or in the ajax call...

Probably I'm thinking along some too complicated lines, don't let me
distract you too much from the root of the problem...

Cheers,
Olaf

Re: [OpenSTA-users] Load testing best practices

[Corey G. <cgo...@ea...>]

> JVM settings or threading settings etc.


There are books specifically relating to Java testing/tuning.  One that I like is:
"Performance Analysis for Java Websites" (Joines, Willenborg, Hygh)

For a more general approach,
check out Scott Barber's http://www.perftestplus.com
In the 'Resources' section, he has a lot of good writing that is worth looking at.

Microsoft has been creating a body of knowledge available at: http://www.codeplex.com/PerfTesting
It has some really good information and they are actively adding to it.  Most of it is obviously geared towards .NET and their proprietary VSTS tools, but it also contains a lot of general information that can be applied to any system or tool set. 

.. though most of this stuff deals more with methodology than technical specifics.

If you come up with a good report and are able to, post it to this list :)

Re: [OpenSTA-users] Load testing best practices

[robi s. <ro...@gm...>]

This is a pretty good link and a pretty good discussion on a high
level of testing but I was hoping for something that was more detailed
that, for example, might talk about things the difference between
testing a system cold (where you just hit it with some test) as
opposed to ramping it up and why you might do one or the other.  Doing
things like maybe making sure to cycle the server between tests where
your changing, for example, JVM settings or threading settings etc.
Thats probably way to specific but I am looking more for links I can
point to as further reading for links I can use to back up my own
testing assertions or if need be ones that refute my assertions so I
make sure to represent reasonable accepted best practices :-)

Once again thanks for the link though its appreciated and ill probably
included it in a slide of references.

I'm not sure if this is what you are looking for... but someone (Bernie) posted a good high level summary of his performance testing strategy to this list recently.  

I republished it on my blog:  http://www.goldb.org/goldblog/2007/03/12/BernieVelivisOnPerformanceTestingStrategies.aspx

Re: [OpenSTA-users] CPU usage is showing 100% with 200VUs

FYI to the list, Dev and I talked off list and I had a look at the scripts. 
The wait commands generated during the original recording were commented out 
(maybe a couple of minutes worth) and replaced with a handful of 1-2 second 
waits. Script execution was therefore throttled primarily by server response 
time and it makes sense that 200 scripts running in parallel would consume 
the majority of his server's CPU capacity assuming the system under test 
could service the high request rate without slowing down considerably.

[OpenSTA-users] Load testing best practices

[robi s. <ro...@gm...>]

List,

I am supposed to be giving a presentation on using open source tools
for Testing, Tuning, and Troubleshooting J2EE application servers and
I am wondering if there is a list of Best practices for OpenSta or
testing in general.  I have googled some but can not find anything
that really talks about best practices for various types of testing
and maybe I am not phrasing my Google queries well but I thought I
might ask the list.

Thanks,

Robi

If it's a text-based application, then you could probably automate it using a generic scripting language like Perl, or a more specialized language like expect/tcl (both open source).  You wouldn't get fancy graphs as easily you would with a fancy load test tool, but you also wouldn't have to learn how to use a complex load test tool.
