Introducing the Virtual User Generator (VuGen)

HP’s tool for creating Vuser scripts is the Virtual User Generator,
VuGen.

During recording VuGen monitors the client end of the database and
traces all the requests sent by the user and received from the user, to
the server.

During playback, Vuser scripts communicate directly with the server by
executing calls to the server API.

When a Vuser communicates directly with a server, system resources
are not required for the client interface. This allows a large number of
Vusers to run simultaneously on a single workstation, and few testing
machines are required to emulate large server loads.
