Hi all, could you please help me with this question:  

We use Performance Center in order to simulate bandwidth of 100 MBytes ( indeed we have 1 GB).

So we go to Runtime Settings > Speed Simulation and use the following: 838860800 (bits in 100 MBytes) / number of Vusers in scenario. First of all, is it correct?

We suppose to see reponse time higher than usual and network utilization less than usual.  It's true about response time, but we are not sure about accurate limitation of bandwidth - if we go to one of our load generators, the graph of Network Utilization seems to be the same for different bandwidth defenitions.  

In other hand, our load generators are virtual (VMWare), so Network Utilization may be shown incorrect.  Please recommend how can we check the bandwidth changing (or how can the bandwidth on virtual load generators can be limited)  

Thank you!  

Yuliya

P.S. Unfortunatelly, we have no Shunra's network virtualization.

Recording SAP BusinessObjects BI 4.1 with 'BI launch pad'?

I am having the following challenge when trying to record SAP BusinessObjects BI 4.1 SP4 (with BI launch pad).

When using HTTP protocol first steps are recorded OK.
However when a report is launched in a browser:
1) New jp2launcher.exe process appears in Task Manager.
   (Is this Oracle Java Web Start launching a Java applet in a browser?)
2) This jp2launcher.exe is doing something useful because it consumes CPU cycles.
3) Nothing is recorded in VuGen after this point until logoff.

Do you have updated recommendations specifically for BusinessObjects BI 4.1 by any chance?

Are recommendations in KM169714, KM185190 and KM11878 still valid and should be followed?

For example, one of the recommendations is "install VuGen preferably in a path without spaces".
My VuGen is currently installed in "C:\Program Files\HP\Virtual User Generator\bin" folder.
Does it mean that I need to reinstall my VuGen?

Currently I use VuGen 12.50 Build 1096 on 64 bit Windows 7 with IE11 browser.

I see "Recording in 32-bit mode: C:\Program Files\Java\jre1.8.0_31\bin\jp2launcher.exe" message in a recording log, but it doesn't look that this recording has captured anything.

Thanks for this useful information,i was looking for the same, from where we can get that formula to calculate the parameter we want to substitie,is it somthing  from java  IDE or in vugen tools itself.

While using the lr_load_dll function, the following error happens:

Action1.c(x): Error -19890 : C-interpreter run time error:
Action1.c(x): Error -- File error : LoadLibrary(c:\temp\MyDll.dll) failed : The specified module could not be found.

You will get the error above if the compiler fails to locate or load the DLL. You can check the return code of lr_load_dll to verify if this is the case.

Example:
int x;
x = lr_load_dll("cfgamp16");
lr_message("return code = %d", x);

If the function above returns 11, that means LoadRunner failed to find the file. Check the following:
1. Double check the directory, and make sure that the DLL is in the correct path as specified in lr_load_dll function.
2. Make sure that all the required files are present and available to the DLL.
You can use the Windows Dependency Walker to check if any dependent DLL's are not available.
3. Is your DLL an 8-bit or 16-bit DLL? If so, it is not supported.
4. If you are getting this error from the Controller only:

1. If you are loading the DLL from a specific directory, make sure that you copy the DLL to the same directory of all the Load Generator machines.
2. If you are loading the DLL from the script's directory, make sure that the DLL is listed in the Controller's Design View -> Details -> More -> Files.
3. If you are still having problems, try to put your DLL into a path that is specified in the PATH environment variable of the machine. Modify the reference to the DLL if needed.

Oracle Forms Java applet not launched during replaying

Hello,

Hope you can help me.

I've recorded a script using Loadrunner 12.02 and HTTPS+Oracle NCA Protocols. Previously the administators allowed me to record object names, so at this point that is not a problem (I think).

The issue is that when I replay the script the java applet login is not launched. An error is returnet when I try to perform an action against an object on this non-loaded applet: Window or object is disabled

- While recording no similar issues have been detected.

- I've used "nca_get_top_window" to see which is the active windows and it returns null.

- I don't know if this is important, but no "ICX Ticket" is recorded in the responses (while recording, of course).

- I've correlated "jsessionId" (I don't know if it matters).

- No pop-up is launched (at least I haven't see it in the extended replay log)

Can you help me, please?

Best Regards.

We are looking to upgrade from 11.5 to 12.5. I have only found one document listing the requrements but now sure if the requirements are for the Controller machine or the vugen generator machines. Could someone please tell me what the rewuirements are before installing controller and Vugen 12.5. Below is the information I have:

Processor speed  Dual-Core 2.2 GHZ or faster Operating system  ·         Windows Server 2008 R2 SP1 64-bit ·         Windows Server 2012 R2 64-bit (recommended) ·         Windows 7 SP1 32-bit or 64-bit ·         Windows 8.1 64-bit (recommended) Memory (RAM)  Recommended: 8 GB Screen resolution  Minimum: 1366x768 Browser  Microsoft IE (Internet Explorer) 9, 10, or 11  (It is recommended to keep the default IE settings)  Available hard disk space  Minimum: 50 GB

This requirement are for both (VuGen / Controller) ,

But recommended that the machine that run the load test should be more stronger than the minimum requirement .

Hi, 

It is JavaScipt. For more details about Math.random() function and haw it can be used, please check:

Hello Yuliya,

Regarding your questions:

100MB =100MB*1024=102400KB*1024=104857600Bytes= 104857600Bytes *8 =838860800 Bits

So, your calculations are correct.

In LR you can limit a bandwidth the single VUser can use, but not the bandwidth for a load generator (LG). Limiting the bandwidth for a single LG can be achieved by multiplying the bandwidth a single VUser have (set by runtime setting) with the VUsers running on the LG.

The last suggesting might be because you set height limit for a single VUser and the limit has never reached, You can try limiting the Vusers to a unreal small bandwidth (for example 30 BITS) and check if there is a change. Note this ways all transactions might fail, but you will prove the bandwidth limitation is working.

Thanks and Regards,

ivo

Hello,

 

It is common issue, mostly happens due some differences between record and replay, so I’d suggest to compare them carefully (recording and replay logs I mean, please switch them at fully extended mode before recording and replay). Besides that, if it possible for you – you can open official ticket for HP support.

 

Thanks, Dmitry
