Comment on Benchmark testing tools for Web Services by damitha23

damitha23 — Wed, 04 Nov 2009 04:21:43 +0000

To answer your first question,
I send a simple hellow message in a post request as follows

ab -T “application/soap+xml; charset=UTF-8″ -p data/input/hello-message.xml -n 5000 -c 60 http://localhost/services/HelloService/ > results/hello-message.txt

My hello-message.xml file is as following

Hello World!

To answer your second question:
Do you want to send file attachements within your soap message?. In this case you need to use base64 encoding or mtom attachements.

thanks,
Damitha

Hello Damitha,

Let me start by saying that your blogs are very informative and technical. I would love post some questions on SOA/Web Services.

But right now I am trying to bench mark different web servers along with different file systems. I am planning to use ‘ab’ too.

I am planning to send POST requests. Could you please send me a sample POST file you used with -p option. Is there any way I could send upload file request within the POST data file. I am planning to send a HTTP POST request for uploading/downloading static data files which are of different sizes

Comment on Plot diagrams with gnuplot by sahan

gnuplot is indeed a damn good tool … you can automate most of the graphing part (even the changing .dat file part – with the help of awk, sed, perl).
This web site is a very good reference : http://t16web.lanl.gov/Kawano/gnuplot/index-e.html

Comment on What is good for Axis2/C pthreads or cbthreads? by damitha23

damitha23 — Mon, 04 May 2009 02:02:35 +0000

It is not correct say that Axis2/C is bound to Apache. It is true that Axis2/C can run as a module in Apache. But it do so also with IIS. It was a design decision at out set not to depend on APR because that could be problem with scripting language/browser integration.

Comment on What is good for Axis2/C pthreads or cbthreads? by Roberto

Roberto — Sun, 03 May 2009 14:02:27 +0000

Hi Damitha,

since axis2/c is already bound with apache modules, why not use apr_thread_proc?
(at least it is APL-licensed and plain C)

Ciao!

Hi Gagan,
Please send your problem to Axis2/C dev mailing list axis-c-dev@ws.apache.org. If you send more details (may be code of your client program and your request as captured by tcpmon etc etc) it will be more helpful for the people there to help you

Hi Damitha,

I am trying to write a web service client in AXIS2C but I am hitting a road block when I am trying to consume a web service. I somehow feel it may be related to the SOAP header etc. I am getting the error message while trying to consume the web service:

http://www50.brinkster.com/vbfacileinpt/np.asmx?wsdl

————-
The value of the input node is 9
It has come in this function
The payload sent here is 9
The value of the node is
soap:Server
System.Web.Services.Protocols.SoapException: Server was unable to process request. —>
System.ArgumentOutOfRangeException: Length cannot be less than zero.
Parameter name: length

at PrimeNumbers.PrimeNumbers.npr(Int64 inf)
at PrimeNumbers.PrimeNumbers.GetPrimeNumbers(Int32 max)
— End of inner exception stack trace —

————-

If you can provide some code if you have something ready or any pointers where things may be going wrong, it will be really helpful.

Just stumbled upon this entry. I too had the same problem – need to do performance testing against a HTTP endpoint with postfiles. Suprisingly difficult to find a tool that does this well…

I’m in agreement with you, I’ve been using AB for about 3 years now, and its hugely successful. A very good combination of what you want, and simplicity. Easy to setup/configure/modify, good level of statistics, and can effectively pound the crap out of your webserver.

My only gripes with it are:
- unable to support HTTP Digest
- unable to support client-side x509 certificate authentication (does support SSL well with openssl built in).
- no ability to ramp up users and concurrency – its all or nothing.

I’ve been looking at curl-loader as a possible substitute, but it doesn’t seem to do postfiles either (hard to tell though).

I have been looking for a way to load-test our postgresql servers, so I have tried tsung and so far I am very impressed. Having said that, I was also fortunate enough to attend the 1st Erlang Exchange meeting in London a few weeks ago, where the people who have actually written this stuff staged a tutorial!

Tsung is not meant to be a ‘I shall repeat this POST request one million times per second and see what happens’ tool. One of its strong points is you are able to generate “realistic” testing scenaria, which may be as complex as you like, including parsing results and performing dynamic substitution for subsequent requests.

The easiest way to get started with tsung is to use its “recorder” mode – you may use a tsung process as a proxy, use your browser through this proxy to do everything a user would do and a tsung configuration file is automatically generated for you.

I know things in the open source world sometimes are not as user-friendly as they could be, but tsung is definitely worth another look if you are serious about load-testing with “realistic” test cases.

Comment on Soap Action and Addressing action by damitha23

damitha23 — Mon, 07 Apr 2008 18:17:38 +0000

Hi jvleminc,
You need to specifically set soap action in your Axis2/c client as follows to make it send soapAction http header.

axutil_string_t *soap_action = axutil_string_create(env,”axis2/c/samples/echoString”);

axis2_options_set_soap_action(options, env, soap_action);

By doing just

axis2_options_set_action(options, env, action);

add addressing action soap header. Note that if you call this function in your Axis2/C client application addressing will be automatically engaged even when you don’t specifically call

axis2_svc_client_engage_module(svc_client, env, AXIS2_MODULE_ADDRESSING);

To learn more about more about ws addressing read article

Hi,

I am making my first steps with axis2c, coming from a java world it is …different Anyway, I wanted to know if your client (using axis2c) sends a Soap-action in the http header, since mine doesn’t seem to set it and I don’t understand why Thanks a lot and keep up the good work !
