Recently, I needed to setup an Oracle monitor in LoadRunner so I decided to take some screen shots along the way so that I could post them along with some instructions. I do this because I know I will forget how to do this in the future, so when the next project rolls around that requires it, I can search Google and find my own article on the topic. It’s a great ego booster. Maybe you are looking to do this, and it will help you too.

Whenever I go into a project where previous LoadRunner testing did not include proper monitoring (b Read Entire Entry

LoadRunner 9.52 is mostly bug fixes, but I wanted to key in what’s new with it:

Flex Protocol Enhancements. Improved support of externalizable objects and general protocol usability. Updated user interface for Recording Options and Run-Time Settings (Flex > Externalizable Objects node). Added Code Generation Errors dialog box that displays details about errors, as well as recommended actions.
Web Services protocol enhancements. The Web Services protocol now supports JMS messages based on JMS topics and Windows authenticat Read Entire Entry

The user wants to open a file existing on a remote machine in VuGen, but using the fopen function causes a C interpreter error. What this error means is that there was something wrong in the syntax, but the problem comes up only when file is stored in the remote machine.

The host name itself contains two backslashes as a part of the name. So, in order to specify the complete path of the host machine, you need to precede each backslash with another backslash.

If you are having an issue trying to select certian perfmon counters for the Windows Resources monitor when using the Monitor Over Firewall in LoadRunner, there is a patch from HP which will correct this. It is basically an updated cm_nt_monui.dll file (located under the \BIN folder in your main LoadRunner install directory). Save off the old one by renaming it first, then replace the new one. You can get this patch from HP support by opening an incident report.

Here is what the issue looks like:

Most people who use Vugen and have a development background know loops. In C or most other programming languages, a loop is a loop. Sometimes in my classes I will ask students the main difference between a “do while” loop verses a “while” loop to see if they have that programming background. A “do” loop requires that the code you want to run does execute at least once before checking the condition to see if it should run again. But how about a real world example when scripting for a load test?

Is there a way to set the Analysis Tool to open new graphs with a custom granularity? For example, LoadRunner may open all graphs with the granularity set to 300 seconds. Is there away to set it to 10 seconds?

Solution

Create a user-defined template for the Analysis tool. There is no way to set the same granularity to all graphs in Analysis once the result set has been processed. However as a work-around, create and use a user-defined template.

Open a result set in Analysis.
Open up all sets of graphs.
In each graph, s Read Entire Entry

I was wondering about how Global Filters are applied in an Analysis template and how the template DEF files could be modified if you wanted to make one simple change to your template but did want to create a template from scratch . I got this information back from HP Support which has information in it about Global filters that I did not know:

“Applying a global filter sets ALL the filter fields of ALL opened graphs. If the global filter’s field is set to a value different than the default one (almost always empty), this filter i Read Entire Entry

Recently I was working on a Citrix testing project with LoadRunner and I was reminded of all the server settings for the Citrix servers and Generators that have to be checked, in addition to all of the Vugen script run-time settings, and script enhancement. In some cases, we at Loadtester have had to become part-time Citrix server administrators to get our projects done on time. One of the Citrix server settings we always recommend initially is for any session that disconnects to be reset to login, instead of leaving it open. This Read Entire Entry

What is the official word from HP on PC and virtualization? Well, according to KM752992 in the HP Knowledge Base:

The following considerations apply when planning the deployment of Performance Center and/or LoadRunner within a virtualized environment:

Load Generator:
This component can be affected by timing issues that result from being operated within a virtual environment. As a consequence it is not recommended to run the Load Generator for load testing purposes in a Virtual Environment when timing accuracy is a Read Entire Entry
