Hai.....
Unlike a WinRunner workstation which emulates a single
user's use of a client, LoadRunner can emulate thousands of
Virtual Users.Load generators are controlled by VuGen
scripts which issue non-GUI API calls using the same
protocols as the client under test. But WinRunner GUI
Vusers emulate keystrokes, mouse clicks, and other User
Interface actions on the client being tested. Only one GUI
user can run from a machine unless LoadRunner Terminal
Services Manager manages remote machines with Terminal
Server Agent enabled and logged into a Terminal Services
Client session.
During run-time, threaded users share a common memory pool.
So threading supports more Vusers per load generator.
The Status of Vusers on all load generators start
from "Running", then go to "Ready" after going through the
init section of the script. Vusers are "Finished" in passed
or failed end status. Vusers are automatically "Stopped"
when the Load Generator is overloaded.
To use Web Services Monitors for SOAP and XML, a separate
license is needed, and vUsers require the Web Services add-
in installed with Feature Pack (FP1). No additional license
is needed for standard web (HTTP) server monitors Apache,
IIS, and Netscape.
K,Byeee...
