Looking at Vuser Types
LoadRunner provides a variety of Vuser technologies that enable you to generate
server load when using different types of client/server architectures. Each Vuser
technology is suited to a particular architecture, and results in a specific type of
Vuser. For example, you use RTE Vusers to operate terminal emulators; TUXEDO
Vusers to emulate TUXEDO clients communicating with a TUXEDO application
server; Web Vusers to emulate users operating Web browsers. The various Vuser
technologies can be used alone or together, to create effective load testing
scenarios.
The following table summarizes the use of the various Vuser types:
Vuser Type
Used to Emulate ...
Database
a database (CtLib, DbLib, Informix, Oracle, and ODBC)
application accessing a server. Database Vusers use
API calls to directly access a server.
TUXEDO
a TUXEDO client communicating with a TUXEDO
application server. TUXEDO Vusers use API calls to
directly access a server.
APPC
a client application communicating with a server using
the Advanced Program to Program Communication
(APPC) protocol. APPC Vusers use API calls to directly
access the server.
