  • Using C Macros in LoadRunner Vugen

    Posted on May 5, 2014 by Admin

    Introduction to C Macros
    C macros aren’t  discussed a lot by HP LoadRunner users, yet they are at the core of the C programming language used in VUGen. They can provide flexibility and power that reduces script development and maintenance times. A good example would be where a function cannot be used to encapsulate reusable code blocks because something in the code block must be known at compile time instead of at run time. In this case, there would be a global variable accessed within the code block, but the name of the variable Read Entire Entry

  • LoadRunner 12: Manage Cloud Load Generators

    Posted on April 21, 2014 by Admin

    In our last blog article, we went through setting up an Amazon AWS account for EC2, and configuring AWS and LoadRunner in preparation for using Load Generators from the Cloud. At this point, we are ready to use them in a load test scenario.

    Let’s first look at using an existing machine. I installed a Micro instance of Windows 2012 Server (Standard Edition) in EC2. It’s really slow and won’t do much. HP does not recommend a Micro account, so keep in mind we’re only trying to demonstrate the features at this time. Th Read Entire Entry

  • LoadRunner 12: Configuring Cloud Load Generators

    Posted on April 14, 2014 by Admin

    Let’s explore using Load Generators from the Amazon EC2 Cloud in LoadRunner 12.  Many people have asked me about it, wondering about any “gotcha’s” that might be out there. I have found a couple. In this blog entry, I want to focus on the configuration and setup of LoadRunner. There is quite a bit to consider.

    First, set up an account instance on Amazon EC2. I was able to set up a free account with a Micro instance of a Windows 2012 Standard machine in less than thirty minutes.  However, using the Micro instance is no Read Entire Entry

  • LoadRunner 11.5 – VuGen Revamped

    Posted on June 20, 2012 by Admin

    New Vugen Platform: SharpDevelop
    To say that the look and feel of VuGen received a makeover in LoadRunner 11.5 would be somewhat of an understatement. It is a total rework from the ground up. The biggest change is the move from LCC and the GNU Pre-processor engine to the SharpDevelop platform. This has to do with what the custom (HP) code for VuGen sits upon for compilation. This in and of itself warrants a healthy discussion and a separate blog entry. It appears this move affords HP a little more benefit to add additional features Read Entire Entry

  • What makes a good Performance Engineer?

    Posted on October 8, 2004 by Admin

    Note: This article was originally posted on Loadtester.com, and has been migrated to the Northway web site to maintain the content online.
    I was asked recently to describe in my own words what qualities a good performance engineer would have, as they were trying to make a decision on hiring a resource for their company. I came up with some stuff and thought it might be good to share it with you and offer it up as a discussion topic in the Forums for the site. Perhaps you can add your own input and help businesses make informed hiring Read Entire Entry

  • Performance Engineering Skills: Raising The Bar

    It is unfortunately clear that everyday more and more people enter our quality assurance profession with very little software architecture of engineering background to draw from. This is bad enough on the functional side, but is getting darn near catastrophic on the performance side. And, by the way, this is for all vendors, not just Mercury. It just may be more apparent here due to Read Entire Entry
