While you may mean well, I would encourage you to seek the information on your own. The question you describe is core to the understanding of loadrunner and if you are having to ask about the answer, clearly you have no understanding of LoadRunner.
I would encourage all who read this to not answer ladybird. It is ethically irresponsible of use to provide her with answers for a tool designed to measure the risk of deploying enterprise applications. I would not provide test answers to Doctors pursuring their medical boards, to CPAs pursuiing their accounting certificate and I am unlikely to provide answers to those who haven't done the work and don't understand the tool for LoadRunner.
Best of luck. All of your answers to questions posted here and also on the LoadRunner Yahoo groups forum are covered in both training and the documentation.
