We recently published information on our web site about our HP training classes online, with outlines that can be downloaded in PDF format. We have had a few questions about the classes and I wanted to try and answer a few of them here.
What classes is Northway Solutions Group currently offering?
ALM/Quality Center training, QuickTest Pro training based on Unified Functional Testing, and Application Performance Testing training based on either LoadRunner or Performance Center. You can find out about all the classes and our curre Read Entire Entry

This past January, I attended the HP Global Partner Conference. I listened to an informative session by Gartner. According to their surveys, the top three initiatives for CIO’s this year are:

Business Intelligence
Cloud Computing
Mobile

Here’s the latest graphic from Gartner for Emerging Technologies:

Why Business Intelligence?
The BI and analytics market was the second-fastest growing sector in the overall worldwide enterprise software market in 2011. IT continues to spend on it, and it Read Entire Entry

LoadRunner 11 has added the AJAX Truclient protocol, and with it new functions for it that are unlike the old C-based functions. As of this writing, there still isn’t an entry in the function reference for the protocol with examples of usage, but only documentation found in the help documentation.

However, recently we found that some of these functions are not correct. HP recently added a new knowledge base article address this:

If you need to create a GUID on the fly for a unique ID, here is some code to do just that. Thanks to Chris Butts for this.

Here is the GUID function. Set this somewhere outside the Action() function to keep it separate.

lr_message(“%s”, lr_eval_string(“”));

We have been working with a client for weeks to solve an issue with LoadRunner 9.52 that I am happy to report is now solved.

Problem: After creating a Citrix script in Vugen and getting a successful playback on a local machine, the script would be moved to the LoadRunner Controller to test it out with multiple virtual users. Sometimes the scripts would throw the error, “Failed to retrieve the ICA client Bitmap: Reason: The server threw an exception”. This happened for all ctrx_sync_on_windows functions on all scripts, but onl Read Entire Entry

I was using the stand-alone version of Vugen used with Performance Center 9.5, and I noticed that it would crash every time I tried to create a parameter file.

After some research, I found out it is because SQL Server 2008 was installed on the machine. Apparently, Vugen is doing something that conflicts with the mfc80.dll or mfc80u.dll file used by SQL Server 2008. This problem not only affects Vugen, but other applications as well.

We have experienced a bug in the LoadRunner 9.52 patch when trying to install on a 64-bit OS. Installing 9.5, and 9.51 works just fine. However, when trying to install 9.52 – it can’t find an existing Loadrunner installation.

After some research, we located this article:

Our theory is that LR 9.52 patch does not realize it is running in a 64-bit environment and probably Read Entire Entry

Note: This blog post was originally published on Loadtester.com as an article. We have re-published here as an effort to retain useful information from that web site after merging with Northway Solutions Group. Some material may be slightly modified to retain relevance.
This week marks a milestone for me personally, as well as for Loadtester as a company. Two years ago, we had an idea to create a utility to be used to make our lives as LoadRunner consultants a little easier. There have been a few stand-alone utilities that have been Read Entire Entry

Web/AJAX Protocol:

KM840444 – Using the Web HTTP/HTML protocol in LoadRunner 9.51 or 9.52, after recording the business process the body portion is missing in the web_custom_request when the script is generated. No error message is displayed in the log files, either during record or replay.

For example, with LR 9.50 the recording of an HTTP POST request to a SAP server generates the following web_custom_request code:
web_custom_request(“runtime_2”,
“URL=http://hostname.domain.org:50000/xxx/yyy/zzzzz”,
“Method=POST”,

Sometimes you need to strip off the first part of a string because there is some character and/or amount of crap at the end that you don’t need. The most obvious use of this is when you capture an e-mail address as a parameter and the string is like:

giggity@loadfreakintester.com

Let’s say all you need is the “giggity”, and not the rest. If you capture the exact same thing each time, you can just strip off anything after the 7th character. But what if the next time you run the script you captur Read Entire Entry
