HP LoadRunner Questions Bank: Q. 31 to 40
Learn “Controller” Module of HP LoadRunner through FAQs:
Q. 31: What is the meaning of rendezvous status for a Vuser?
Rendezvous status for a Vuser indicates that the Vuser has arrived at the rendezvous and is waiting to be released by LoadRunner.
<<<<<< =================== >>>>>>
Q. 32: What is the purpose of Gradual Stop option for the Vusers?
Gradual Stop option Instructs the Controller to complete the current iteration or action before stopping the Vuser. This option is only available when the Vuser is in the RUN state.

Q. 33: How do we modify the run-time settings of multiple scripts?We need to chose the method of modifying the run-time settings:
1) Modification method for Shared run-time settings: This method opens one window containing all of the run-time settings in blank mode. In this mode, we set only the options that we want to modify for all selected scripts. All other run-time settings remain unchanged.
Some of the run-time settings cannot be modified in shared mode. These settings do not appear. To modify them, we need to open the run-time settings for each individual script.
2) Modification method for Individual run-time settings: This method opens a separate window for each selected script. In this mode, we modify each script�s settings individually.

Q. 34: What configuration settings we can define for Load Generators in a scenario?
With the help of Load Generators dialog box, we can set following type of load generator�s attributes:
1) Defining which load generators will run Vusers in the scenario. For example, if a load generator is unavailable for a particular scenario run, we can exclude it temporarily instead of removing it entirely from your list of load generators.
2) Selecting which load generators will take part in the scenario by using the Enable and Disable commands. Disabling a load generator temporarily removes it from the list. Enabling a load generator reinstates it.
<<<<<< =================== >>>>>>
Q. 35: What is the role of controller in LoadRunner?
The Controller monitors a Windows load generator�s CPU usage and automatically stops loading Vusers on a load generator when it becomes overloaded.
We can monitor the status of a machine�s CPU usage. When the CPU usage of a load generator becomes problematic, the icon to the left of the load generator name contains a yellow bar. When the machine becomes overloaded, the icon contains a red bar.
<<<<<< =================== >>>>>>
Q. 36: What are the Terminal Services in LoadRunner?
Terminal services allows centralized management of computing resources for each client connected to the server, and provides each user with their own working environment.
We use LoadRunner�s Terminal Services Manager to remotely manage multiple load generators running in our load testing scenario on a terminal server. With the help of Terminal Services Manager, we can select the number of terminals to be used in our scenario & the maximum number of Vusers which can be run per terminal. The Terminal Services Manager then evenly distributes the number of virtual users among the client sessions.
With the help of Terminal Server Client, we can operate in a server-based computing environment from a remote machine. The terminal server transmits applications over the network and displays them via terminal emulation software. Every user logs on and sees only his individual session, which is managed transparently by the server operating system, independent of any other client session.

Q. 37: What is the use of Creating a Manual Scenario Using the Percentage Mode?
A manual scenario is created in the Percentage mode by defining the total number of Vusers to be used in the scenario, and assigning load generators and a percentage of the total number of Vusers to each script.
While creating a new scenario, we can access the Percentage Mode directly by selecting the “Use the Percentage Mode to distribute the Vusers among the scripts” in the New Scenario dialog box.
A scenario created in the Vuser Group Mode can be easily converted to the Percentage Mode.
<<<<<< =================== >>>>>>
Q. 38: What are the key considerations while converting a scenario from Vuser Group Mode to Percentage Mode?
1) In case we have defined multiple scripts for a Vuser group, the number of Vuser scripts created in the Percentage Mode will be same as the number of scripts defined for the group.
2) All Load Generators will be assigned to all Vuser scripts created in the Percentage Mode. In case we have defined multiple load generators for a Vuser group, the Vusers we assign to the scripts in the Percentage Mode will be distributed evenly among the load generators previously assigned by us to the group.
3) All Vuser group schedule settings will be lost. All profiles will contain scenario schedule settings only.
<<<<<< =================== >>>>>>
Q. 39: What are the key considerations while converting a scenario from Percentage Mode to Vuser Group Mode?
1) Each script will be converted to a Vuser group.
2) In case we have defined multiple load generators for a Vuser script, the Vuser group which is created when converting the scenario will also contain multiple load generators.
3) All schedule settings will be retained as it is.
<<<<<< =================== >>>>>>
Q. 40: What is the purpose of Scheduling Scenarios?
After creating a scenario, we schedule it to start running at a specified time. We can make a schedule defining the time at which to initialize, start, and stop Vusers during the scenario run, and how long an action should continue running.
We can restrict the execution duration of the scenario or of a Vuser group within the scenario. We can also stipulate how many Vusers to start and stop running within a certain time frame. We can specify whether LoadRunner should start or stop running all Vusers in a scenario simultaneously, or only a certain number of Vusers within a specified amount of time.
