This blogspace is meant to be a one-stop shop for anybody wanting to learn about HP Load runner.
LoadRunner is HP’s tool for application performance testing.LoadRunner stresses your entire application to isolate and identify potentialclient, network, and server bottlenecks. LoadRunner enables you to test yoursystem under controlled and peak load conditions.
When i started load runner i dont know from where to start. So i thought of posting my experiences to beginners. My intention here is to collate the useful information on Loadrunner scattered all over the web.
Performance Testing
Performance Tests are tests that determine end to end timing (benchmarking) of various time critical business processes and transactions, while the system is under low load, but with a production sized database. This sets ‘best possible’ performance expectation under a given configuration of infrastructure. It also highlights very early in the testing process if changes need to be made before load testing should be undertaken. For example, a customer search may take 15 seconds in a full sized database if indexes had not been applied correctly, or if an SQL 'hint' was incorporated in a statement that had been optimized with a much smaller database. Such performance testing would highlight such a slow customer search transaction, which could be remediated prior to a full end to end load test.
Start -> All programs -> Loadrunner -> Applications -> Virtual User generator
Select New Vuser Script or go to menu options (Click on File -> New)
New Virtual User screen is displayed
Verify that ‘all protocols’ is selected in Category Drop down list
Based on Ur application u need to select New Single Protocol script or New Multiple Protocol script
(For ex suppose ur application deals with only web like HTTP/ HTML then u can select web(HTTP/HTML) else if ur application deals with both web and some other software like Oracle NCA u have select New Multiple Protocol Script and u need to select both Oracle NCA & Web(HTTP/HTML))
Click on OK button after u select valid protocol/ protocols
A New Window ‘Start Recording’ dialog box is invoked
Specify the Valid address in URL and Select Vuserint in record to action
When ever u record using LR u need select Vuserint for Login details
Where as in action block u need to record the actions like“ wat u want to test in the application”
In Vsuerend u need to record logout information
Click on ok button and now u can see Loadrunner records the actions that u perform on the application

Is the recording changes from the proxy selected. If i have sample application and I dont know the software that they used to develop the application. Then how can i know wat proxy i need to select?
we cant select any proxy with out analysing the application properly. For loadrunner first of all before testing application u need to know infor abt software that is used to develop the applciation and also whether the application is dealing with any third party software. Let me if u have any doubts.
Thanks sirisha
