Loadrunner 12.01 - Throughput, Response Time Drops

Hi,

 

This may not be a tool issue but wanted to get an opinion on the below issue seen.

 

I ran a 12 hr soak test (LR 12.01, HTTP) and test runs fine the first two hours and then just after two hours the throughput and response times drops (see figure attached). The server CPU/Memory usage was less than 10%. 

 

The test continues to run (i.e. I can see transactions going through) but at a lesser throughput.  

 

Checked the servers (4 Tomcat) but all were seen to be active BUT two of the server logs were seen not to be updated with any information after the two hours. Developers checked the Tomcat servers and confimed that all was fine and severs were runnning/ active. Got in touch with the Networks team who confirmed that they could not see any errors in the LoadBalancer logs (F5). 

 

 

I ran the test the second time with the same results. A bit confused as to what to check next.  

 

Regards,

TTS

I tried to record simple scripting using Web+citrix protocol for capturing events, but when trying to establish connection i am receiving a "unsupported function" window.

 

I am assuming that Vugen 11.52 should be compatible for citrix Xenapp 5. Please let me if other

 

I have about year of experience Load testing Citrix related application using LR 9.5 using only citrix protocol alone (by log on record mode and Via ICA file record mode).

 

 

1. Xenapp 5+ installed in Win 2003.

 

a. Citrix online pulgin 13+

b. Citrix receiver 3+

 

2. Application are hosted in the citrix server and accessed via web interface.

 

3. Vugen 11.52 installed in Win 7 (64 bit).

 

 

solution tried:

 

recorded with admin rights -no use

 

disabled anitvirus - no use

 

checked/changed settings DEP (data execution prevention)

 

merged registry settings from "enable_citrix_api.reg" - no use

 

 

 

 

Please help!

Hi,

 

Posting in the general forum, as I dont know whether everyone has access to customer support forum or not.

 

Vugen is throwing exceptions in the following cases:

 

1) While running the script. Solved after re-saving the script with a different name. 

2) Every time I am trying to open an action.  - attached image lr-1.jpg. Had to close the Vugen process explicitly.

 

There are other exceptions that are coming up. If anyone wants to get those, I'll start capturing them too.

 

A LR crash report came up after closing the vugen process. Below are the contents.

Hi folks,

 

I'm using Citrix/ICA single protocol script to capture a Citrix business flow. As part of the flow, there is a unique number generated which i would like to capture in the script. I understand that we have a function named ctrx_get_text function that could be used to capture text - however per HP's Function Reference "ctrx_get_text function is available only if the LoadRunner agent is installed on the Citrix server" 

 

I do not have an Agent installed on the Citrix server so is there any otherfunction that could be used to capture this unique piece of text from the screen? Please let me know. 

 

Appreciate any help.

 

Thanks,

Kunal

I build serval truclient scripts for firefox with VuGen Version 12.01. During a load test started from HP ALM 12.01 i get an error for several virtual users:

 

ReferenceError: step is not defined

var retVal = true;
var step = e.target;
if (step.readyState._aborted) {
retVal = false;
delete step.readyState._aborted;
}
else if (step.readyState.isReady) {
if (step.type == "handler" && !step.preemptive) // Do not allow other handlers to interfere?
disableHandlers = true;

 

After this error message the user process is still running but the script itselfs stopped. Does anyone has an idea, it is quite urgent.

// Note - when calling the state setter the step is pushed into the Step.STATE_* array
step.state = Step.STATE_RUNNING;
step.run.callAsync(step);

}
else {

step.state = Step.STATE_RUNNING;

if (Script.state == Step.STATE_STOPPING)

else
step.onReadyTimeout();
}
}

Hi,

I’m working with Virtual User Generator12.01 to run API’s.

I need to add new lines to the post entity description field (one of the entity parameters is “description|” that support new lines in it).

I have tried 3several combinations like /n, /n/r, //n//n, %0D%0A and so on.

For example: "\"description\":\"text text text //n text text text\",”

How can IO enter new lines???

Please help…

 

Thanks,

I have downloaded LR 12.1 evaluation from HP site and tested AJAX Truclient protocol for a web application with 5 users.

Observed high CPU utilization for AJAX Truclient protocol – IE. Each TcWebIELauncher.exe instance is taking 15% on average per instance, for 5 concurrent users CPU utilization is around ~ 75% and test is failed and stoped with error “Error: CPU usage for this load generator has exceeded 80%” after 20 min test execution. Results were also not saved for the test executed. Used different load generator also and observed same. Can you please advice to run the test with out any failure for longer durations.

Hello,

 

I am scripting on BMC Remedy ITSM 7.6 web client and I use the Truclient for Firefox protocol becuase the plain web http/html with Remedy DFE is not fully functional and can't replay correctly all the backchannel requests.

 

At the login, if the user previously didn't disconnect correctly, the browser sends a windows.confirm message asking if the user wants to take control of the session and override the already opened one.

 

I wanted to use the event handler on this event but the object is not recordable as it is from the firefow itself and not the page. So i cannot use event handler on this message.

 

How can I test in javascript if the window.confirm box is tdisplayed in order to use afterward the available truclient step that simulates a user clicking on OK in the confirmation message box.

 

Regards, FG.

I have been trying to capture script for the application - Informatica Business Glossary desktop by Informatica organization. It is a very simple tool but I am unable to use any of the existing protocol to record this application in VUGEN 11.50. Has anyone successfully created a script for this tool in VUGEN 11.50? If yes, can you share the protocol to be used along with any settings to be done in the recording options.

Hi,

We are trying to prepare the script for a Web Service. We are using SOAP UI request message generated from Web Service WSDL. We are using HTTP/HTML protocol and passing the SOAP UI request with web_Custom_request . We have found following observations. • When Web Service Binding is SOAP_DOC_LITERAL the web_Custom_request is Failing with the SOAP UI message generated from this WSDL. And • When Web Service Binding is SOAP_RPC_LITERAL , the web_Custom_request is executing successfully with the SOAP UI message generated from this WSDL. The client wants the Binding of Web Service as SOAP_DOC_LITERAL but in this case script is not working. Please suggest how to proceed the scripting in this scenario. Any kind of help will be useful.

I am running a script in LR 11.52, TRU client Firefox protocol. The website does a couple of calls to external websites, that I don't want in my test results.

 

So I try to block them like this:

 

Utils.addAutoFilter("https://ssl.synovite-scripts.com", false);

 

But when I use this, I still see when I replay he script messages in the bottom right of the screenlike this:

 

Connecting to https://ssl.synovite-scripts.com

 

I tried to change the value of "false" to "true", but then the entire website is not loading, so that is not the answer. Why are there still calls to the external website, and how cann I block this?
