Issue while setting up Controller scenario to execute Ajax TruClient IE scripts from a LG

August 2, 2016, 11:20 pm

The Ajax Tru Client IE scripts have been developed in Vugen 11.52 and IE 10 in the same Load Generator machine that I am trying to connect from the Controller.

Load Generator : Vugen 11.52 | Load Generator 11.50 | IE 10                       Controller machine version 11.52

The error details in Controller output window are as listed below:
Error: Vuser failed to initialize extension LrWebIEReplay.
Error: Exception was raised when calling per-thread-init function in extension LrWebIEReplay: System Exceptions: EXCEPTION_ACCESS_VIOLATION
Error: Exception was raised when calling event-notify Vuser function in extension LrWebIEReplay: System Exceptions: EXCEPTION_ACCESS_VIOLATION

The error details in output window of Loadrunner Agent service are as listed below
Error: Communication error: Failed to bind socket while calling bind function. [MsgId: MERR-10344]
Error: Two Way Communication Error: Function two_way_comm_create_acceptor failed. [MsgId: MERR-60999]
Error: Failed to create "launchservice" server. [MsgId: MERR-29974]
Warning: Extension launcher.dll reports error -1 on call to function ExtPerThreadInitialize [MsgId: MWAR-10485]
Error: Vuser failed to initialize extension launcher.dll. [MsgId: MERR-10700]

What I have tried
a. Setting Loadrunner Agent to run as a service
b. Setting MI Listener name to the Controller machine name and the MI Listener username and password
c. Enabling Firewall Agent and Terminal services
d. Not able to run the Loadrunner Agent as a process due to admin rights restrictions)

With Dummy web (http/html) script, I am not facing this problem.
Load Generator Version is 11.50 and Controller Version is 11.52
I am trying to execute the script from the Controller by selecting the Load Generator in the list of machines in the controller scenario.
I am not able to run the script as localhost from the Controller machine because the script has been developed in LR 11.52 and IE 10 in the Load Generator machine. But in the Controller, the version of IE is 11.
So I am not able to run the script from localhost as the virtual user goes to the run state but no pass / fail transactions are recorded

the script has been developed in LR 11.52 and IE 10 in the Load Generator machine. But in the Controller, the version of IE is 11. So I am not able to run the script from localhost as the virtual user goes to the run state but no pass / fail transactions are recorded

magnetservice.exe is running on ports 50500, 54345, 5003 and 443 in the load generator machine

Hi,

Transaction recorded in vugen version 12.01 with java protocol, creates new object which is used in the next transaction. When replay, I need to parametarized it.  I was trying to debug java code to find the class returning the value but not with much success so far. Any good technic to help with this process?

When the transaction completed, there is confirmation popup window with the object value displayed which I can re-use but vugen doesn't record popup window.

Thanks, Irina

Autocorrelation corrupts HTML script

I was building autocorrelation rules for OpenPages application, when suddenly correlation started corrupting Action.c file.
When I click "Design Studio" and correlate at least one parameter VuGen generates statement like this:

web_url("cognos.cgi_11",
        "URL=http://sv123455.corp.com/ibmcognos/cgi-bin/cognos.cgi?b_action=rc&rsid={OP_Chart_rsidURL}&f= ... ",
        "Resource=1",
        "RecContentType=image/png",
         "Snapshot=t133.inf",
        LAST);hot=t133.inf", 
        LAST);

Please pay attention to the last two lines of this statement.

This behavior happens on two different machines.
Regeneration of a script doesn't change this behavior.
It happens when using my correlation rules and when using "Record scan" option.
Correlations still work OK in another script.
This script was recorded and partially correlated using VuGen 12.02 and then copied to a machine with VuGen 12.50.

Do you have any idea what can explain this issue and how to fix it?

P.S. I will try to finish correlations manually and will try to rerecord the same script.

Hi,

I recorded my entire business scenario in Action() block of ajax truclient and it is working fine while replay. But when i  copy paste the login part in init() and logout part in end() block, the script is failing in Action() block. Is there any Run Time setting that i am missing? to make the flow works across all blocks.

Any help would be appreciated.

Hi

As you hinted, I belive that this is because recorded in 12.02 and edited in 12.53. Maybe 12.53 calculate how correlated lines are displayed or indented  diffrently.

As I see it you have three things to try.

1. In the 12.02 script remove all auto correlations and then open the script in 12.53 and use the design studio.
2. Rerecord the script in 12.53
3. Open a support case with HP

Hi,

  I would like to know how loadrunner analysis process the result data. Total Transaction count in COMPLETE DATA is lesser than count in SUMMARY DATA of analysis.

In Summary DATA: Total Transaction count was 11,694.

In Complete DATA: Total Transaction Count is 10,987

How does loadrunner clubs the multiple transactions?

Thanks

I've run into som funky business with autocorrelation, too. I've seen a few instances where I record, auto-correlate, and the auto-correlate generates a script that isn't even valid C. When that happens I back off and do it by hand.

Correlation with icx_ticket and JsessionIDForms

Hi There,

I'm a newbie to LoadRunner and would like to use it for Oracle EBS R12.2 Load Test.

I have generated simple script in VuGen using multi protocols (Oracle NCA + HTTP) but run into below error

Error: nca_connect_server: cannot communicate with host xxx.yyy.net on port 8000

I googled and found icx_ticket and NCAJServSessionId correlations are required (In fact, JServ is old techstack and no longer used) and tried to resolve it on my own but no luck.

Here is part of my script and I will need to correlate icx_ticket and JsessionIDForms I believe

Would you please tell me how to correlate them?

Auto Correlation doesn't help at all.

Thank you very much for your help in advance

Re: communication between trueClient and VUgen

We are encountering a similar issue.  We are new to the TruClient Web protocol.

LR v 12.5, Windows 7.  We had to reinstall LR because the Firefox auto update was on and HP recommended to copy version 37.02 to the install directory or repair the LR install.

We tried TruClient Web with IE11: During recording everything froze when selecting the Login button for the application.  TruClient development window does not allow for anything to be selected. We eventually get the same communication error as above " a communication error occured between the TruClient browser and VuGen".

We tried TruClient Web with Firefox (our preferred browser).  The built in Firefox version with LR 12.5 is 37.02.  Our recording went smooth. Replay hangs.  There were times when I replayed the first login that it eventually ran after about 15 minutes but then would never perform the next step that I selected to run.  It eventually allowed me to save the TruClient development and exited back to VuGen, however the recording did not save when I went back into TruClient development. Most of the time we continue to get the message that a communication error occured between the TruClient browser and VuGe.

We have disabled antivirus, HIPs and lowered UAC.  Is there anything else we need to check in a registry or Record/Reply settings ??

Thank you !

Chris

How to read content from a file and storing it in a string variable?

August 4, 2016, 6:41 am

I want to read the content of a file and store it in a string and use it as part of my script.

Right now i am doing it with the below code:

char Content[2936];

InPutFile=fopen(Filename,"r");
fread(Content,sizeof(char),2936, InPutFile);    
fclose(InPutFile);

I have manually checked the size of the file from properties and used the same (2936), which i want to avoid.

Is there any better way to do it? Especially when we don't know the size of the file.

Hi

If you don't know the size of the file, you can always allocate the buffer larger. fread will return the size of the file read.

long fp, length; // for reading command output
char buffer[4096]=""; // allocate memory for the output of the command.

fp = popen("file_path_to_wanted_file","r");
length = fread(buffer, sizeof(char), 4096, fp);

And it can of course be done more dynamically, but this works and is pretty straight forward

Hello

What I have believed to think is that the summary data is not a summary, but an estimation. How this estimation is done, I don't know, but is calculated faster than the actual amounts.

I have seen the same thing for the number of errors during a test.

Hi Pawel,

From the console log, I can see that you are using 12.53; am I right?

If so, could you please navigate to "%APPDATA%\Hewlett-Packard\TruClient" folder and rename "tcweb2_user_prefs.json" to "tcweb2_user_prefs.json.old"

Once you do that, could you please open TruClient Firefox again, see if it helps? If not, could you please attach a new snapshot of the browser console after the file rename?

Best Regards,

 Eyal Jakov

Urgent help needed - Error: ctrx_sync_on_window("Windows Logon") failed. The window does not exist.

Hi,

I need an urgent help.

When i replay the recording 50 times (50 iterations) in Vugen, i will not get any failures. but I am struggling with Controller from last 2 days. When i put the load with 10 users, it is working good. but when i increase the number of users(up to 30) the Scenario is getting failed by the below error.

Action.c(8): Error: ctrx_sync_on_window("Windows Logon") failed. The window does not exist.

This is the only error i am getting for 15 scenarios which i have to Load test(I thought all the 15 scenarios will work good in Controller when there is no error while replaying the script in Vugen). This is a windows application inside Citrix. I am using True-Client also for this. 

Please find the attached screenshot of my Script and also the Controller error message.

Hello Experts,
I have few questions to clarify on loadrunner installation and license. Can you please suggest.
 
 
1)I did full installation on Machine A, which we will be using as Controller
2) I did Load generator installation on Machines B, which we will be using as Load Generator.
 
 
My question is:
 
1)After the installation, on Authentication setting how can we get the certificates? Will it be any issue if we skip authentication setting and proceed further?
 
2)Should we do any configuration to have Machine A and Machine B communicate. I installed the Load agent and set to run as Service. Apart from this , do we need to do anything else?
 
3)Should we download MI listener on Controller Machine or Load generator Machine? What are the configurations do we need to do after installing MI Listener? 
 
4)Should we install Monitor over firewall on Controller Machine or LG Machine?
