• LoadRunner Analysis Templates and Filters

    Posted on October 26, 2009 by Admin

    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

  • Citrix Presentation Server Settings and LoadRunner

    Posted on October 20, 2009 by Admin

    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

  • VuGen: Dynamic Transactions Created From A Parameter File

    Posted on August 28, 2009 by Admin

    From Michael Hendershot

    Based on the search item I choose, I want a different transaction. This pulls the transaction name from parameter file and generates the transaction name off the “SearchFieldTransaction” column in my parameter file. Be careful. Tree view will take the “tmptransactionname” out of the lr_start and lr_end transaction.

    char tmptransactionname[25];

  • Error on LoadRunner 9.51 Installation

    Posted on August 10, 2009 by Admin

    A new knowledge base article is available on the HP Support side for LoadRunner 9.51. KM753044. If you get the following messages during installation:
    “Another instance of the program is already running.”
    “Setup has determined that a previous installation has not completed. You should restart your system in order to complete this process.”
    It is possible this is coming from conflicting software. Software such as Tivoli or Radia installed on the system interfere with the installation of LoadRunner.
