What are the advantage of using load runner.
1-loadrunner automatically records the performance of the client/server during test.
2-loadrunner checks where performance delays occur network/client delays.
3-loadrunner monitor the network and server resource to help the improve performance.

1.in Process based vuser memory utilization is high(to check the o/s) as compared to thread based Vuser2.everu Vuser takes 4 mb of space

What is a LoadRunner Agent? Why is it used? Where does the Agent run?
jagadeshwar reddy.k
- Apr 18th, 2007
1)Load runner agent communicates between load generator and controller2)Agent will pump the load(number of users) generated by load generator to the controller3)The executable file is Analysisui.exe

LoadRunner Agent establish the communication between the LoadController and LoadGenerator, While running the scenario in LoadController All Vusers will be pumping from the LoadGenerator to LoadController by using Agent processvenkat

How to conduct Regression testing using LoadRunner?Give me explanation about HTTP protocols? How we are working on HTTP protocols?In goal oriented Scenarios LoadRunner provides five different types of goal-oriented scenarios, if a tester can work on five types of scenarios or any one type of scenarios? Suppose loadrunner controller is in different place, Vuser generator is one more place we r working in another place, is loadrunner 7.2 or higher versions of loadrunner provides this facility work (that is using desk top to work on load testing) or not?What are the types of checkpoints is available in LoadRunner? How to work on database check points?While the script is running we find some values that may be need to be correlated? Is it possible to do manual correlation for those values?After completion of functionality testing what makes us to know whether the product is ready for performance testing or not (not related to task distribution diagram and transaction profile document)?

What is ramp-up and ramp-down in load runner
ashish_tyagi123
- Mar 22nd, 2007
Ramp up and ramp down features in the controller allow scaling of users up and down at the start and end of test.Ramp up can also be used to determine the break point of an application.
Vimalkanth
- Feb 20th, 2007
Ramp up - This is not a mandatory step as such. But this is followed as best practice. This will tell how you want to increase the load on the server. This will also help to check threshold point.Ramp down - reverse of above.

How many Vuser you dealt with in your current project? 1 Vuser = How many real users?
nsarathc
- Mar 9th, 2007
If you want to simulate 1000Real Vusers... You need 1000Virtual Vusers....1VUser = 1 Real UserAt any point 1Vuser can't simulate multiple sessions...Instead

It depends on web site loadIf we want to test 1000 virtual users we can take liesence of 100 virtual usersthen the ratio is 10:1

I'm planning to use QTP scripts in LoadRunner. I have 2 doubts.Do I have to install the client application on the machines where I'm planning to use it for load test? so that it helps during the play back of the QTP scripts? for example :Assume I'm using one machine and I'm planning to run 1 vuser. I would install the client application on that machine. When we are executing through controller we can see the application being played back(which is the usual way of executing QTP scripts). If I need to run for 100 Vusers then do I need to have 100 machines with the client application installed on each of them to run for 100 Vusers?Let me know ur thoughts. Thanks

I need to validate the performance of ODBC application which uses RMI and CORBA interfaces. I was using the RMI- Java Protocol or Corba Protocol (there is no option in LR to select both the protocol at a time).

How to analyse online monitors?
kishoreqc
- Feb 2nd, 2007
Based on the vuser monitor what is the trans resp time at a point like 2000 vusers what is the throughput for the same(2000), what abt the network delay etc by using merge graph. we can compare the graphs in Y-axis.

Yes we can use LoadRunner for the desktop appliocation. When you start load runner VU generator, it asks you to select the type of protocal to use. There you have plenty of options from E-business application (web based) to client/server applications. Hope it helps

What are the process for developing a vuser script.
There are 5 steps for developing a vuser script.
1-recording the vuser script .
2-edit the vuser script.
3-runtime setting .
4-run the vuser script in stand-alone mode.
5-incorporate the vuser script into a load runner scenario.
