Host is machine which execute the vuser script.Ģ0. using controller you control all the vuser in single work station. When multiple vuser to perform tasks at exactly the same time then insert the rendezvous point to emulate the peak load on the server.Ĭontroller is manage and maintain the scenario. Transaction measure the time, which takes for the server to respond to task submitted by the vuser. The vuser script includes the function that measure and record the performance of the server during the scenario. While run a scenarion every vuser execute a script that script known as vuser script. LoadRunner replace the human user with vuser. LOADRUNNER Interview QuestionsĪ scenario defines the events that occur during is testing session. 3-loadrunner monitor the network and server resource to help the improve performance. 2-loadrunner checks where performance delays occur network/client delays. LoadRunner accurately measure and analysis the system performance and its functionality.ġ0.What is the advantage of using LoadRunner.ġ-loadrunner automatically records the performance of the client/server during test. Parameterization is generally done to test with multiple set of data or records. What are the reasons why parameterization is necessary when load testing the Web server and the database server. Secs_secs /* current number of seconds */Ĭurr_hr = lr_eval_string(“”) Ĭurrent_time = hr_secs + min_secs + secs_secs ħ.
Min_secs, /* current minutes converted to secs */
Hr_secs, /* current hour converted to secs */ Long current_time, /* current number of seconds since midnight */ This main use of this functions to return the current system time at any given point of time while LoadRunner script is running.This functiona can be used to report transaction times, script starti time and end time.Ĭhar * curr_hr /* pointer to a parameter with current clock hr */Ĭhar * curr_min /* pointer to a parameter with current clock min*/Ĭhar * curr_sec /* pointer to a parameter with current clock sec */ This function is developed to usein Mercury LoadRunner peformance tool.
Web Server works on and through LAN,WAN,or LoadRunner Function – How to get current system time
What are the Vuser components in LoadRunner?ĪpplicationComponents used are client, database or additionally business application server.) If system bottle necks observes in very begining or minimum no of Vusers no further addition of vusers will be considered unless observed bottleneck is resolved.ĥ. That too inturn depends on various factors like entire system configuration etc. How many users can I emulate with LoadRunner on a PC?ĭepends on system response. Monitor system bottlenecks during a test run and capture and display the performance data from every server or component.Ĥ.
Furthermore any protocol that communicates over a windows socket can be supported.Ģ. Industry standard protocols for example HTTP and ODBC are explicitly supported by LoadRunner. LoadRunner Interview Questions for freshers experienced :-ġ.
