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.
Load runner Testing process involes 6 main stages
Planning the test -> Creating Vuser scripts -> Creating Scenario -> Executing Scenario -> Monitoring the Scenario -> Analysing Test results
Before testing any application using Load runner we need to analyse the application. When analysing the application we should become thoroughly familiar with hardware and software components, the system configuration and typical usage model. Because the testing environment you create using load runner should reflect the environment and configuration of the application.

How can i use load runner to test Database jobs initiates by Tivoli job.
Hi surya. I cant understand your question. U can use load runner to load test any application? can u be bit more elobrate. Becoz i dont what ur application is and what tivoli job it intiaties. It makes more sense right? If you are looking some thing database testing u need to select DB2CLI proxy(for tivoli databases jobs) as far as i know. Pls be more elobrate and i need to know more abt the application and what sort of testing u r looking for
