Loadrunner Insufficient records for Parameter

Hello,

I am using a .dat file that has the parameter settings as: Unique, Each Iteration, and Continue in a cyclic manner. This should theoretically never actually run out of data because it should be reusing the data. However, after every line is used up, the rest of my iterations fail out because of an insufficient records error in Loadrunner.

Is there some special setting I need to use to get loadrunner to recognize these parameter settings in VuGen? Are there different parameter settings I should be using?

P.S. I am using loadrunner 12.53 with Oracle protocol. The dat file is being used to login users, and the users can have an infinite number of sessions opened.

 

Thanks.

Hello,
I am using the trail license for Network Virtualization to understand the concept and demo our client on licenses and benefits of Network virtulizaion within loadrunner.

As i was working on it, question came up on my mind, how does NV actually works.

I am trying to simulate a scenarios where Application servers(Data Center) located in Texas and users are trying to connect from different location and load generators are located in New York.


Scenario A)Users in New York, Load Generator in New York, application servers in Texas.

Scenario B) Users in Washington, Load Generator ​in New York, application servers in Texas.


In controller i have selected Virtual location settings
Under Virtual Location: Added the two locations(NY to TX and WA to TX)
After that i configured the settings as follow:
1)Select Virtual location definition Method--> Custon
2)Network Profile settings-->Gave Latency, Packet loss etc
3)Run time setting
​ And applied all above settings to the scenario and started the test.

After the test, i compared the response time between Scenario A and Scenario B and there was about 20-30% difference in response time.

​I was wondering how this is calculated. Just giving the location name will simulate the network from particular location to Data Center?

Is my assumption correct. Please advise.

Hi,

I am not able to connect to Oracle database through VTS Connection string,

I am using using OraClient11g_home1_32bit x32 client and Loadrunner 12.01.

I have a problem of getting Some VUGEN scripts from a recent scripting task to RUN in ALM Performance Center having worked perfectly well in VUGEN. 

I have 10 scripts that work in VUGEN - 50% Fail to Run in PC

When transferred to ALM Performance Center. Some of these scripts function and some do not make it to the Run Stage. The VUsers initialize but they TimeOut because they have not progressed to run the script.

I increased the delay for time out to 3 minutes and this had no impact.

Any assistance would be greatly appreciated.

Hi, I am facing a recording issue under Win 7 Professional SP1 and Firefox.

In the recording options, I setup a port mapping entry for a ssl url with the correct SSL version and cipher and ssl test is successfully. However during recording, the browser automatically redirected to the non-ssl url and cause my script failing. When manually open the ssl url, the browser works properly.

Is there anyone have the same issue before? Any advice is appreciated!

Hi all,

 

I've read somewhere that JavaScript code requires more memory and CPU to run than C code withing LoadRunner load generators. About 50% was one estimate I read in a blog.

Is there an official estimate or something I could read about this subject?

We are trying to decide between coding in JavaScript or C (for the HTTP protocol) and such an estimate would be helpful.

Hi,

i am currently trying to load test a web application using LR 12.53 installed on windows 2012 server.

I am using simple script that loggs in waits and loggs out,

i noticed that only the 2 first users, out of 10 assigned are able to login, while the rest fail, i tried to run 2 scenarios and again, only 2 first users in each scenario (total 4) are able to login.

The AUT is the new HP service manager we are planning to upgrade in our company.

Does anyone has any idea what can the problem be?

Thanks in advance for any input.....

Hi,

I have a TruClient that executes a C function to connect to a database and execute some SQL statement like below:

void cleanDbBuffers()    
{
    
    lr_db_connect("StepName=CONNECT_TO_DB", 
                  "ConnectionString=Data Source={LRP_DS};Initial Catalog={LRP_DB};Integrated Security=false;user id={LRP_DB_USER_ID};password={LRP_DB_PASSWORD};" ,
                  "ConnectionName={LRP_DB}",
                  "ConnectionType=SQL",
                LAST);
    
    lr_db_executeSQLStatement("StepName=DROPCLEANBUFFERS", "ConnectionName={LRP_DB}", "SQLStatement=CHECKPOINT;DBCC DROPCLEANBUFFERS;", "DatasetName=ResultSet", LAST);
    
    lr_db_disconnect("StepName=DISCONNECT_FROM_DB","ConnectionName={LRP_DB}", LAST);
}

The function executed successfully. However, the 3 calls to the database all show up as Transactions in the Analysis Summary Report.  See attached image. Does anyone know if there is any way to disable them from showing up as Transaction?

Thanks!
Jason

Hi,

I have come across the challenge in adding Java Code to generate client side dynamic value to the Web Protocol script. I know any java script can be added by using "Add File to each script" option and also we can use Javascript language as well.

But, i'm not sure whether the Java Code snippet can be exactly used in Web Protocol. I have seen this options in RPT Tool and even JMeter as well.

To Add Java Code, is it like converting Web Protocol script to Java Vuser script is the only way in LoadRunner? If so, license constrains always exist because of this one option, we might need to purchace the License bundle.

 

Please do suggest if there is any option available apart from the above mentioend options.

Hi,

We are testing a REST service protected under SSL with TLS 1.2 Protocol and https session, with a specific Certificate. The scripting is already developed and works fine.

The problem is that this service can't reach the desidered throughtput and for increase capacity, has implemented an option, the RESUME SESSION with TLS 1.2

With this funcionality once the session has been stablished, can be reused (more information at this link: https://vincent.bernat.im/en/blog/2011-ssl-session-reuse-rfc5077

a lot times, saving the time to hanshake certificates and manage private keys.

The question is- How can we implement this functionality with Load Runner?

Is it possibble? Can anyone help me with information of an example code, if there is any?

any information about this is appreciated.

LoadRunner Version - 12.50

Hi,

We have tested the Qlik Sense based application which was developed with Angular JS,Canvas,etc., We checked lot of time with web protocol. But the script was hitting only the proxy server  and not loading any values in the front end due to lack of communication in the engine server.

So, We checked it with HP and went with Tru Client Finally.

What is my question here is logically the Graph page loading  was not captured even with Developer tool or loadrunner with web protocol. Even automation tool was not able to handle the Graph Elements.

The above explanation suggests no tool can't support with Web protocol since most of the call are rendered from front end with JS. Here, will we able to test it with Neoload or VSTS or JMeter or any tool with web protocol?

Hi Folks,

I have to record a application flow which can be opened only by Internet Explorer 9 that too only through "Run as different user" mode with credentials?

Bcoz the loadrunner captures only the IE windows which is opened by 'Record" Option. But I have to start IE separately as run as 'different user" and navigate the applciation.

Please help me to resolve this issue?

Also I tried like giving "web_set_user" fucntion with credentials in init and started recording but it's asking me to replace the old record which mean replacing the web_set_user.
