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.
Most of collegues ask me we have recorded a script and i wud like to know where the run time settings are saved?
The runtime setting are saved in defualt.cfg, located in the Vuser script director

Can u let me know wat is the use of changing run time setiing?
Hi mahesh,
The run time settings are very important to LR controller. U can change the run time by opening defualt.cfg file. But more easy way would be go Menu options Vuser-> Runtime settings
U can see Run time settings dialog box is invoked.
U can find Iterations where u can change Number of Iterations in Run logic. Like how many times u want the action block to be exceuted and also u can specify if u want to continue on error in Miscellanious and also u can specifed the desired Proxy settings based on ur application.
Hope u find the information Helpful
Thanks sirisha..
Hi Mahesh,changing runtime settings allows you to emulate different kinds of user
activity. For ex: you could emulate a user who responds immediately to output from the server, or a user who stops and thinks before each response. You can also configure the run-time settings to specify how many times the Vuser should repeat its set of actions.By enabling thinktime,we can reduce VUser load on the sever While rinning controller.

Nice attempt. Kaani it is very basic. would have loved to see getting into more details and nitty gritties
