Load Generator on Linux: Create Mutex Error [MsgId: MERR-10344]

0
0

I am encountering an error condition when attempting to connect my local LoadRunner Controller to a remote Load Generator agent running on a Linux host.

The error occurs after I have been using the agent on the remote host for several months.  That is, I am able to use the agent to run load tests successfully for a considerable amount of time (>150 days) until this error begins to occur.  Once the error condition occurs, it will persist until the host server is rebooted.  Shutting down and restarting the load generator software does not solve the problem.  Whatever the root cause, it appears a reboot of the host resolves the underlying condition.

Here is what I think is the primary log message of interest:

Error: Communication error: An error occurred while trying to create mutex. (sys error message - No space left on device) [MsgId: MERR-10344]

I have checked a few things:

  • All file systems have available space.
  • System real/swap memory is available.
  • I have attempted running strace against the process and while there are a few calls that return in error, a root cause does not stand out.

Here are a couple of host vitals:

Linux Host OS: RHEL 6.7
Load Generator Version: 12.02

Has anyone discovered a method to resolve this problem without having to reboot the host?

Thanks in advance. -Brian


Load runner is not supporting for WEB RTC functionality.

Hi,

My application was built on Web RTC functionality, am not able to test the load using chromium in LR 12.53 version.

It prompting me with the error "

Incompatible Browser

The video component of this application is powered by OpenTok on WebRTC. To enable this functionality, please use Google Chrome orFirefox."

I have downloaded and installed the latest version of the google chrome browser in my local machine, after installing the latest version again the same issue.

 

Thanks,

TruClient IE - target object was not found running on controller

0
0

I'm on LoadRunner 12.50.
IE version 11.

I recorded a script in TruClient IE and it runs fine in Development mode as well as the load mode in VUgen.

But when I run the same script from the controller, that get pushed out the the Load Generators, I get messages "failed - target object was not found."  

The snapshots from the failures show a smaller-sized browser window during the run.  Smaller window size than the recording/development mode.  I'm guessing it couldn't perform certain actions because the location of the elements on the page get shifted around due to the small window size?

If so, how do I fix it?

I tried setting the Runtime setting > Other Settings > Non-interactive window size > tick the Apply window size by user > set the width 1280 and Height 1024.

That didn't help.  The snapshot still show a small capture.  Is there something else I can look into for this problem?

Thanks.

Seeing discrepancy for the same performance metric in windows resources compared to perfmon

Hi, 

I was trying to validate the accuracy of the %processor time (total) captured in Windows Resources in HP LoadRunner Controller and saw that it is quite different from the same metics seen using Performance Monitor. 

Please have a look at the screenshots captured between 4:31:30 and 4:31:40. A spike between 40% and 50% was seen in Performance Monitor but it was around 20% when seen in Windows Resources. 

I am pretty sure this is not a one time glitch. I observed for a long period of time and continue to see the discrepancy. 

Any idea why there is a discrepancy? 

Thanks!

0

We have the requirement to load test the FICO Debit Manager (DM9) application but we are unable to record any event starting happening in DM9. It is a Java based application. We hit the URL in the browser and it launches a desktop application.

Using VuGen 12.53 and different versions of browser, java and vaniala version of DM9 but no script is generated.

Tried with following protocols:
1. Web HTTP/HTML
2. Windows Sockets
3. Java over HTTP
4. Java Record Replay
5. Web HTTP/HTML and Winsock

We are able to record using RDP which has its own limitations and the requirement is 300 concurrent users to login and do the activities.

Any suggestion or help would be highly appreciated.

How are transaction response times impacted when a step verification is added in TruClient

0
0

Hi,

In Web (HTTP/HTML) protocl scripts we do a step verification using the web_reg_find LR function so similarly in my TruClient scripts within a transaction I am adding a generic object action with either a 'Verify' or 'Get Visible Text' in the step action to verify if I get the required result for my critical transactions.

Now my question here is the end event of recorded business step is set to 'Document Loaded' or 'DOM Content Loaded'  so is it still required to add the verification using generic object action to validate the required result of the step?

I use a third part tool called "HTTP Watch" to capture End-to-End client response times and when compared with Truclient transactions I see a difference of atleast 20-30% where TruClient transactions have taken more time than HTTP Watch recorded transactions.

Need some suggestion/guidance here.

Thanks,

Bibhu Panda.

Hi Team,

I am facing issue with HP Vugen. I am not able to replay any script (WEb-Http/html and Web services). My Vugen hangs infinitely when compiling.

Solution Tried so far : 

1. Restarted system many times.

2. Reinstalled loadrunner.

3. Deleted Result folder and tried replay again. 

None of the issue worked so far for me. Please let me know if anybody has faced similar issue. 

LR version :12.01

Below logs are generated in tmp folder while this compilation process was in progress :
